If You Build It, They Will Definitely Structure Their Roster Differently

The New York Yankees will kick off their 2019 postseason when the Minnesota Twins come to Yankee Stadium for Game 1 of the American League Division Series on Friday night. Before the team takes the field, Yankees manager Aaron Boone and the front office will have some difficult decisions to make as they assemble a twenty-five man roster for the series.

Some decisions are relatively easy, so it probably makes sense to start by getting those out of the way. First, the position players.

With those uncontroversial decisions settled, there seem to be four more to make: (i) whether to carry thirteen position players and twelve pitchers or vice versa; (ii) deciding between Luke Voit, Edwin Encarnacion, and Mike Ford at first base and designated hitter; (iii) deciding between Cameron Maybin, Tyler Wade, and Clint Frazier as extra outfielders; and (iv) filling out the final three or four pitching staff vacancies.

1. 13 and 12 vs. 12 and 13

The Yankees are likely rolling out this starting rotation in the ALDS.

GameStarting PitcherDate
Game 1James PaxtonFriday, October 4
Game 2Masahiro TanakaSaturday, October 5
Game 3Luis SeverinoMonday, October 7
Game 4Chad Green to J.A. HappTuesday, October 8
Game 5James PaxtonThursday, October 10

In a full five-game series, you need your pitchers to cover at least 45 innings. In a very good world for the Yankees, Paxton probably covers thirteen of those, Masahiro Tanaka covers six, Severino covers five, and Green and Happ combine to cover six in Game 4. In this scenario, you only need fifteen innings from your bullpen over seven days. Before opening Game 4, Green should be available for two innings if needed in Games 1 and 2. Pencil Chapman, Britton, Ottavino, and Kahnle in for three each, and you’re asking your final three pitchers for one inning to round things out. In this case, Boone has hardly used those extra pitchers to get him a nice platoon matchup or eat innings in a possible extra inning game or blowout.

Against an offense like Minnesota’s in ballparks like Yankee Stadium and Target Field, this could easily break down. Maybe you only get ten total from Paxton, four from Tanaka in Game 2, and three from Severino in Game 3. If Green and Happ only get you four innings in a Game 4, all of the sudden, you’re asking your bullpen for twenty-four innings. In a Game 5, it’s obviously all hands on deck. You could have Tanaka ready to back up Paxton in the win-or-go-home scenario for two or three innings. Maybe Green can give you three innings outside of Game 4 in this scenario. Let’s say you ask Ottavino and Kahnle for four each and get three each from Chapman and Britton. In that case, you need four innings from three other pitchers. That doesn’t seem crazy. Even if you up that number to six, it doesn’t feel like the end of the world. And, let’s be honest, if things wind up going this way, the Yankees probably aren’t advancing to the ALCS and not having a thirteenth pitcher on the roster won’t be why.

An extra bench piece feels more necessary, especially on a roster that might be carrying pinch running candidates like Gary Sanchez, Austin Romine, Luke Voit, Edwin Encarnacion, Mike Ford, and even DJ LeMahieu or Giancarlo Stanton off a knee injury. A late game defensive replacement for Stanton in left or one of the first basemen at some point seems like a certainty. Lifting Didi Gregorius in a big at bat against a tough lefty like Taylor Rogers might seem like something that would get Aaron Boone excommunicated by the Yankee faithful, but Didi hasn’t been himself since coming back from Tommy John, and wouldn’t you rather have Edwin Encarnación’s career .374 wOBA and 132 wRC+ or Luke Voit’s .373 and 135 against lefties over Didi’s .295 wOBA and 82 wRC+ in that spot? That means sliding Torres over to short and either LeMahieu moving to second (in the event he starts at first) or Tyler Wade immediately coming in for Encarnación. With only a three-man bench, one of whom is your backup catcher, Aaron Boone seems extremely limited in his ability to make those types of moves.

Verdict: Thirteen position players and twelve pitchers.

2. Luke Voit vs. Edwin Encarnacion vs. Mike Ford

When the Yankees added Edwin Encarnación in June, it seemed like an exercise in excess. A team stacked with power and Luke Voit putting together a solid follow-up to his 2018 Yankees debut didn’t seem to need another slugger at 1B/DH. With Encarnación attempting to return from an oblique injury without seeing live pitching and Voit mired in a 1-for-32 slump since September 15th and slashing .200/.319/.338 since returning from the injured list on August 30th, first base depth has unexpectedly become an issue.

The Princeton University product Mike Ford stepped up in a big way in the second half. In thirty-nine games since August 4th, Ford has slashed .274/.333/.619 with eleven homers. In addition to his MLB breakout, Ford put together a phenomenal season at AAA. He hit for a .419 wOBA and a 151 wRC+, which ranked him ninth in that category among all AAA hitters with at least 250 plate appearances in 2019. Here’s how Ford’s 2019 stacks up against Voit’s and Encarnación’s.

MetricLuke VoitEdwin EncarnaciónMike Ford
Exit Velocity89.7 mph90.0 mph91.9 mph
Exit Velocity FB/LD95.4 mph94.4 mph92.4 mph
Launch Angle12.8 degrees22.5 degrees15.6 degrees

These numbers are all extremely close, although Voit and Eddie have obviously done it over a much larger number of plate appearances. Let’s look at some fielding numbers from 2019.

MetricLuke VoitEdwin EncarnaciónMike Ford

It might surprise you to see that Encarnación is the clear favorite in fielding metrics, but he’s actually rated around average at first base since the start of 2015. Against the Twins probable Game 3 starter Martín Pérez, if Encarnación is healthy enough to make the roster, that allows the Yankees to sit Gregorius, play Torres at short, LeMahieu at second, and stack the lineup with righties against the lefty without losing much in terms of defense at first base. Perez’s 2019 and career splits against righties and lefties are below.

Date Range2019Career
wOBA Allowed vs. R.353.352
wOBA Allowed vs. L.260.283
FIP vs. R5.134.81
FIP vs. L3.023.34

You get the feeling that, if Encarnación is 100% after simulated games on Tuesday and Wednesday (and he apparently is), the established slugger is going to have a spot on this playoff roster. Despite not playing against Texas over the weekend, the New York Post reported that Eddie was showing plenty of power in batting practice last week. This decision is likely between Voit and Ford.

Let’s take a closer look at Voit’s slump. Since August 30th, he’s hit for a .295 wOBA. In that same time span, Ford has hit for a .448 wOBA. But those numbers aren’t telling the whole story. When looking at xwOBA (expected wOBA based on exit velocity and launch angle of batted balls), things get closer: Voit’s xwOBA is .342 since his return from the IL, and Ford sits at .380.

Voit’s slump has been at its deepest since September 15th. His 1-for-32 mark translates to an absolutely abysmal .133 wOBA. Ford’s wOBA over that span: .520. But let’s account for some batted ball luck and take another look at xwOBA to assess quality of contact: Voit’s xwOBA still isn’t pretty, but it’s an improvement at .256. Ford clearly saw some good luck over the last two weeks of the season as his xwOBA was just .327.

Exit velocity can often be an indicator of a hitter’s health. The concern may be that Voit is still suffering from the abdominal strain that landed him on the IL. His average exit velocity on batted balls since August 30th is 91.1 mph, higher than his season average and equal to Ford’s over that time frame. Since September 15th, Voit’s average exit velocity is 91.8 mph. Below is a graph from Baseball Savant showing his rolling exit velocity, which has been rising steadily since his return (the point almost directly between the 225 and 250 marks on the x-axis).

There are a few things to conclude from the discussion above. First of all, Voit’s slump has appeared worse than it actually has been. While he’s definitely struggled, he appears to have also hit into some bad batted ball luck along the way. Secondly, Voit appears to be healthy: his exit velocity is in line with past performance and actually looks to be on the rise.

Mike Ford has had a lot of success in fifty games for the Yankees and at AAA this season. In addition to the numbers above, Ford has an above average walk rate at 10.4% (8.5% is average in 2019) and a strikeout rate much lower than the major league average (23.0% in 2019) at 17.2%. The Athletic’s Eno Sarris recently pointed out that teams that put the ball in play more often tend to fare better in the postseason. That fact certainly makes Ford slightly more attractive, especially compared to a 27.8% strikeout rate from Voit in 2019. But Ford’s success has still only come in fifty major league games. The Yankees have now witnessed 157 games and 658 plate appearances by Luke Voit against major league pitching. Here are Voit’s MLB ranks among the 318 hitters with at least 500 plate appearances since the start of 2018.

MetricLuke Voit (2018-2019)MLB Rank (min. 500 PA)

Ford has been a big part of what has enabled the Yankees to withstand so many injuries and still win over 100 games, and he’s definitely an easy guy to root for. It hurts more than a little bit to leave him off the playoff roster, but expect the Yankees to bet on the larger sample size of dominant offense over the smaller one.

Verdict: Voit and Encarnación over Ford.

3. Maybin vs. Wade vs. Frazier

This one should be quick and dirty.

MetricCameron MaybinTyler WadeClint Frazier

Fortunately for Maybin, he’s the only legitimate fourth outfielder option here, so he walks right onto the postseason roster. His fielding metrics rate him as an average defensive outfielder this season, which neither Wade nor Frazier can say.

Frazier is a talented young hitter, but he hasn’t really shown much in 2019, and he certainly hasn’t fielded the position. According to Baseball Savant, Red Thunder has converted -13 outs above average in the Yankees outfield this season. He’s had particular trouble coming in on balls, where he’s rated ten outs below average. With a history of concussions, you might think that Frazier is playing deeper in the outfield to mitigate the danger of going back on balls at full speed, preventing him from getting to balls in front of him, but that hasn’t been the case. Below are Frazier’s starting depths in left and right field in 2017, 2018, and 2019 according to Baseball Savant.

SeasonAvg. Depth in LFAvg. Depth in RF

It looks like Frazier did play deeper in left in 2018, but he’s played shallower in left in 2019 than ever before and about even with his past depth in right. Frazier’s sprint speed might be to blame for his poor fielding. After posting marks of 28.8 ft/s in 2017 (89th percentile) and 28.2 ft/s in 2018 (78th percentile), Frazier’s sprint speed has decreased to 27.4 ft/s in 2019 (61st percentile). According to Statcast, his fielding has deteriorated each year, but it’s reached a nadir in 2019. His -13% catch percentage added (the percentage of catches an outfielder makes above or below what an average outfielder would be expected to make based on the exit velocity and launch angle of batted balls hit to that fielder) ranks him last of 183 outfielders with at least fifty fielding opportunities. The next closest outfielder has recorded a -7% catch percentage added. If he’s not going to make an impact with the bat, the Yankees just can’t afford to roster Frazier in the playoffs.

Wade’s defensive numbers above are based on 98.0 innings in the major league outfield in 2019. Obviously, Wade has much more experience playing infield and rates about average at second, short, and third. He may not play even average outfield defense (Baseball Savant has him at -1 OAA and -4% catch percentage added), but his versatility in the field make him an asset, especially for a team that has toyed with the idea of using five infielders when Zack Britton’s on the mound. If you’re thinking about pinch running, Wade’s average sprint speed of 29.1 ft/s makes him the fastest Yankee and ranks him in the ninety-third percentile in the league. Actually, Terrance Gore is faster at 29.9 ft/s, but even Wade is a better option to take an emergency playoff at bat than Gore. Wade’s defensive versatility and speed give him the edge over Frazier.

Verdict: Maybin and Wade over Frazier.

4. The Bullpen

The Yankees have five studs in their bullpen that they feel comfortable with against both lefties and righties late in games: Chapman, Britton, Ottavino, Kahnle, and Green (who will likely open in Game 4). Right now, the field for the remaining three vacancies seems to include the following pitchers: Luis Cessa, Jonathan Loaisiga, Stephen Tarpley, Cory Gearrin, Ben Heller, and David Hale. According to Meredith Marakovits, CC Sabathia won’t be on the ALDS roster. Green could handle a slightly longer role in Games 1 or 2 if needed, but without Sabathia, the Yankees seem like they will need at least one long man out of this group.

David Hale only pitched in one uninspiring outing in the final weekend of regular season, and his success earlier in the year was mostly predicated on a low walk rate, unsustainably high infield fly ball rate, and unsustainably low home run per fly ball rate. Despite a 50.0% ground ball rate, all of that combined with a very below average 14.7% strikeout rate make it more likely than not that Hale’s results were more a house of cards than anything else.

Ben Heller had a nice run with an increase in slider usage in 7.1 innings pitched this September, but he wasn’t nearly dominant enough to earn himself a roster spot in such a short stint. His 1.23 ERA belies his 3.76 FIP and 5.06 DRA.

One strategy would be to use two of the last three roster spots on matchup guys. Tarpley and Gearrin are the Yankees most severe platoon options, and together, they might make up one very solid reliever.

MetricStephen TarpleyCory Gearrin
FIP vs. L (Career)2.284.90
K% vs. L (Career)41.3%15.8%
BB% vs. L (Career)12.7%12.9%
xwOBA vs. L (since 2015).247.342
FIP vs. R7.123.24
K% vs. R21.7%25.4%
BB% vs. R13.4%8.5%
xwOBA vs. R (since 2015).417.285

This idea is really attractive in theory, but it feels like a difficult one to pull the trigger on. Tarpley has only faced 63 lefty hitters at the major league level in his career, though the numbers are impressive at AAA since 2018 as well (0.99 ERA, thirty-five strikeouts, and nineteen combined walks and hits allowed in 27.2 innings pitched). His slider, which he’s thrown 47.4% of the time this season, is his only weapon (.270 xwOBA against); his sinker (.497) and four-seamer (.427), which sit between 92 and 93 mph, get absolutely hammered. Without CC on the roster, however, there could be a need for another lefty in the pen.

Since joining the Yankees on August 24th, Gearrin’s tenure has been unimpressive: a 4.79 FIP, 5.77 xFIP, 5.25 SIERA, 5.43 DRA, 111 DRA-, and 13.1% strikeout rate don’t scream playoff roster material. In 2019, his splits against righties have slipped a bit compared to his career numbers, as Gearrin’s seen a decrease in FIP (3.60), strikeout rate (21.4%), and ground ball rate (48.9% to 42.7%) and an increase in xwOBA against (.313) versus righties. A decrease in horizontal slider movement every year since 2017 (3.3 inches above average in 2017 to 1.1 below average in 2018 to 2.5 below in 2019) is probably a large part of what’s behind his declining effectiveness against righties.

When you look at his results compared to his stuff, Jonathan Loaisiga has certainly been a disappointment.


Loaisiga throws a four-seam fastball 47.7% of the time with an average velocity of approximately 97 mph and 1.2 inches more rise than the average four-seamer at similar velocities, good for 100th among 432 qualified pitchers according to Baseball Savant. His curveball, which typically sits around 84 mph, apparently has below average drop but about an inch above average glove-side break (ninety-eighth of 275 pitchers). Despite a seemingly average movement profile, the curve has completely devastated hitters.


According to numbers available at Baseball Prospectus, Loaisiga’s four-seamer and curveball tunnel well together to both lefties and righties, which helps explain the effectiveness in the absence of elite movement. Let’s go to the tape.

The shape of Jonny Lasagna’s curve certainly looks like a high fastball out of the hand and buckles hitters as it starts to break sharply down and towards the left-handed batter’s box.

Remember when Lance McCullers threw twenty-four consecutive curveballs to close out ALCS Game 7 in 2017? This is a weapon you want in the playoffs. Loaisiga only threw his curveball 30.8% of the time in the regular season. Even though it has elite velocity and above average rise, his four-seam fastball consistently gives up loud contact (.423 xwOBA in 2018; .450 in 2019). Loaisiga is fairly predictable with the four-seamer. He uses it around sixty percent of the time on the first pitch and about half the time when even or with the batter ahead to both lefties and righties. With a four-seamer that doesn’t see great results and with a lethal curveball in his pocket, Loaisiga may want to consider pitching backwards more often and getting his curveball usage at least up over forty percent if not to around fifty. One final note on Loaisiga: since August 20th, he has started using a two-seam fastball around 18% of the time with decent results (xwOBA against of .329), which could be something to could an eye on. Control and command are certainly issues for Loaisiga, but his hammer is a powerful threat that the Yankees have to hope to harness in the postseason.

Without Sabathia, you likely need one more long man. In that case, Luis Cessa feels like the obvious choice. Cessa has eaten 81 innings for the Yankees in 2019 and has been fairly reliable if not unremarkable: a 4.87 FIP, 4.30 SIERA, 4.82 DRA, and a 21.9% strikeout rate. Cessa doesn’t really possess favorable splits with career FIPs of 4.52 and 5.30 against lefties and righties, respectively. His slider is his most effective pitch (.306 xwOBA in 2017, .218 in 2018, .245 in 2019), but he’s already throwing it 49.9% of the time in 2019. This version of Cessa appears to be his ceiling. The hope is that the Yankees only need the right-hander in mop-up duty in a blowout in their favor, but he will be useful to have in a deep extra inning game.

Give me Tarpley against a tough lefty in a spot where Boone isn’t quite ready to go to Kahnle, Britton, or Chapman or those options have already been exhausted, Loaisiga throwing curveball after curveball, and Cessa for length if and when the Yankees need it.

Verdict: Tarpley, Loaisiga, and Cessa in the bullpen.

Hope For Happ

It would be a major understatement to call 2019 a disappointing season for New York Yankees left-handed starter J.A. Happ. After the Yankees acquired Happ from the Toronto Blue Jays at the 2018 non-waiver trade deadline, he went 7-0 in eleven starts with a 2.69 ERA, .676 OPS against, and sixty-three strikeouts to sixteen walks over 63.2 innings pitched. After that solid stretch run, Happ gave up five runs in two innings in an ALDS Game 1 loss against the eventual World Series Champion Boston Red Sox.

Since signing a two-year contract worth $34 million with a $17 million vesting player option for 2021, which triggers if Happ throws 165 innings or makes 27 starts in 2020, the thirty-six year old has been more ALDS disaster than solid stretch run for the Yankees. Below are his 2018 and 2019 numbers.


Except for his walk rate, Happ’s seen his statistics deteriorate drastically across the board. Given the league-wide home run surge, his home run rate has not spiked as much as it appears, but it is still above the 2019 major league average. He has the second-worst FIP of all sixty-eight qualified starting pitchers after Seattle Mariners lefty Yusei Kikuchi. According to Statcast, Happ has seen his velocity diminish on most of his offerings as well. Happ throws an occasional curveball, but due to its infrequent use, it is not included in the table below.

Pitch2018 Avg. Velocity2019 Avg. Velocity
Four-Seam92.3 mph91.9 mph
Sinker90.4 mph89.5 mph
Slider85.3 mph84.8 mph
Changeup86.0 mph86.0 mph

The low point of Happ’s season was likely on August 9th at Toronto. He surrendered six runs over five innings on four hits, three walks, and three home runs. The 6’5 southpaw allowed a .467 xwOBA against for the game, the second-worst mark of his season other than his first start of the season against the Orioles on March 31st. The start against the Blue Jays raised Happ’s ERA to 5.48, and it would rise even higher before it would start to fall.

Over his next five starts, which include a start where he allowed five runs in four innings to the Oakland Athletics on August 21st, Happ is 3-1 with a 3.42 ERA, a .557 OPS against, three home runs given up, and twenty-nine strikeouts in 26.1 innings pitched. Here are his numbers before and after August 14th.

3/31 – 8/95.485.6718.6%6.3%.350.335
8/14 – 9/73.424.0927.9%12.5%.255.261

Thirteen walks in 26.1 innings are responsible for Happ’s slightly inflated FIP, but he’s otherwise improved in every aspect. Happ is missing a lot more bats and inducing much weaker contact. The average exit velocity on the batted balls against Happ has decreased from 89.2 miles per hour prior to August 14 to 86.1 miles per hour from August 14th on.

The Athletic’s Lindsey Adler noted in an article over the weekend that Happ feels he’s in a better place mentally now than earlier in the season. Happ also seemed to credit throwing first pitch strikes more often for his recent success, which is puzzling given that his first pitch strike rate through August 9th was 57.9% and 54.8% from August 14th on. Even if you alter the cutoff to be August 21st, when Happ had his poor start against the Oakland Athletics, his first pitch strike rate up to and including that game was 57.3% and has been 58.1% after that start.

Happ might be enjoying a better mindset on the mound, but getting strike one more often doesn’t look like what’s driving his turnaround. The keys to Happ’s recent success appear to be some changes in his pitch mix and the location of his sinkers to lefties and his four-seamers against righties.

Date RangeBatter HandednessExit Velo.Launch AnglexwOBA
3/31 – 8/9Left87.1 mph5.9 degrees.295
8/14 – 9/7Left80.4 mph4.7 degrees.119
3/31 – 8/9Right89.9 mph15.6 degrees.348
8/14 – 9/7Right87.8 mph17.2 degrees.308

Happ has had better success against both righties and lefties in his recent five-game stint, and he’s really been stifling lefties lately.

Below are two tables from Brooks Baseball showing Happ’s pitch mixes from March 31st through August 9th and from August 14th through September 7th.

Against lefties, Happ has dropped the use of slider by nine percent overall and thirteen percent when he’s ahead in the count. He’s using his sinker and four-seamer more often in all counts, and his sinker has become his primary offering when he’s ahead of hitters, particularly with two strikes. With batters on the ropes in two strike counts, Happ’s increased his sinker usage against lefties by eighteen percent and dropped his slider usage by twenty-three percent.

Against righties, Happ has ditched his sinker for his four-seam fastball: his sinker usage against righties has decreased by thirteen percent to just five percent, and his four-seam usage is up from fifty-one percent to sixty-one percent. Happ’s upped his slider usage against righties by four percent overall and a whopping twenty-one percent on the first pitch. Maybe being more comfortable starting righties out with his slider is what he was referring to in his comments about the first pitch.

Let’s see how lefties have fared against Happ’s sinker.

Date RangeExit Velo.Launch AnglexwOBA
3/31 – 8/984.8 mph2.3 degrees.263
8/14 – 9/775.1 mph-21.6 degrees.102

The results are much better. Lefties are making worse contact on average and absolutely pounding his sinkers into the ground. Location might have something to do with the improvement.

In the heat maps above, you can see that Happ was leaving a lot of sinkers out over the middle of the plate to lefties. Lately, he’s done a much better job of getting the sinker inside on lefties, especially low and in just off the inside corner. That location is likely to get hitters to swing over the top of the sinker for more whiffs and get in on lefties’ hands for weak contact. Here’s J.P. Crawford with a swing and a miss on August 26th.

And Happ sawing off Matt Olson for an easy double-play on September 1st.

Finally, Happ gets Matt Olson to ground out weakly into the shift in the same game.

Let’s turn to righties against Happ’s four-seam fastball.

Date RangeExit Velo.Launch AnglexwOBA
3/31 – 8/992.0 mph27.8 degrees.369
8/14 – 9/788.3 mph31.8 degrees.220

Happ’s numbers have also vastly improved with the four-seamer against righties. It’s encouraging to see a higher launch angle here, as that means Happ has likely been seeing more lazy fly balls and less hard-hit line drives and fly balls.

Happ has made a massive shift in his four-seam fastball locations to righties. It looks like he’s targeting the upper middle part of the zone less often and looks to have taken aim at the outside part of the plate. Keeping the four-seamer away from righties rather than getting them to swing underneath the fastball might make some sense given the movement profile on Happ’s four-seamer this season.

SeasonVelo.V-MovVM vs. Avg.H-MovHM vs. Avg.
201892.3 mph14.7 in.1.6 in. (10%)7.1 in.0.0 in. (0%)
201991.9 mph15.4 in.1.1 in. (7%)8.1 in.1.3 in. (20%)

Happ’s four-seamer is dropping more in 2019 and doesn’t have as much rise as it did in 2018. That alone might make the middle-up location less effective for Happ in 2019 as hitters are less likely to swing underneath the old number one. In 2019, when the ball is leaving the park at record rates, throwing pitches in a spot that frequently leads to fly balls is probably not the greatest strategy if you aren’t missing a ton of bats.

While the rise on Happ’s fastball has decreased, the arm-side run on the pitch has drastically increased. He’s getting a full inch more movement away from right-handed hitters on the four-seamer, good for twenty percent more run than the average sinker in 2019. That increase in tailing action may make the outside part of the plate a smart location against righties, who are expecting the pitch to continue towards the heart of the plate but wind up seeing it dart back outside instead. That movement could be helping Happ get more whiffs and worse contact. Watch as Happ rings up Chad Pinder on August 21st.

Matt Chapman fails to pull this four-seamer on September 1st.

Xander Bogaerts flails at a four-seam fastball on the outside corner on September 7th.

Even before the newfound arm-side run on his four-seamer, you can see that Happ targeted the outside part of the plate with the pitch frequently in 2018.

It’s possible that the location of his four-seamers against righties had become too predictable in 2019. Whether it’s the movement, location, lack of predictability, or a combination of all three, Happ seems to have figured something out.

One other encouraging late-season trend has emerged for Happ: the lefty has also regained some velocity as the season has progressed. Below are charts from Baseball Savant detailing the average velocities on his four-seam fastball, sinker, and slider in each game this season.

J.A. Happ might be coming around at the right time for the New York Yankees. As rough of a season as it’s been for Happ, his recent success seems to be supported by some underlying changes that might make those improvements sustainable. If Happ’s success continues on today against the Detroit Tigers and throughout the rest of September, it might make sense to slot him in as the Yankees’ fourth starter in the playoffs and hope for a solid four or five innings before the bullpen takes over. Germán (5.68 ERA and 5.90 FIP since May 26th) might be hitting a wall and likely profiles better as a bullpen arm than Happ. If not, Happ’s recent numbers against lefties look really good from a lefty specialist out of the pen. At the very least, Happ’s recent run has given the Yankees front office a few reasons to look at him as a useful option on the playoff roster.

Torres Gets Comped

On Wednesday night, Gleyber Torres hit a home run to tie Gary Sanchez for the New York Yankees team lead with thirty-four. Despite injuries to Aaron Judge and Giancarlo Stanton this season, that’s still an extremely impressive and unexpected feat for Torres. The twenty-two year old has followed up his rookie year, which earned him a third place finish in the 2018 Rookie of the Year voting behind Shohei Ohtani and Miguel Andujar, with another very solid campaign. Before starting a series with the Boston Red Sox on Friday night, Torres had a .283 batting average, .346 on-base percentage, and .540 slugging percentage in 2019, good for a .364 wOBA. The sophomore’s 128 wRC+ ranks him thirty-fifth among the 143 qualified hitters this season, ahead of players like Edwin Encarnacion, Ronald Acuna, Jr., Nolan Arenado, and Bryce Harper. Torres has shown steady improvement in 2019 over his 2018 performance.


Torres has also made some notable improvements in his plate discipline and contact profile.


According to numbers available at FanGraphs, Gleyber’s chasing out of the zone at about the same rate, but he’s swinging at pitches in the strike zone much more often and, as a result, is swinging more often generally. Swinging more frequently at strikes has allowed Torres to make more contact.


Torres’ walk rate hasn’t really budged, but his strikeout rate has decreased significantly by 4.6%, likely due to his much higher contact rate on pitches outside of the strike zone and an overall increase in contact rate across the board. The heat maps below show that Torres is not only swinging at more strikes but also swinging at better strikes. First, from 2018.

And 2019.

Torres has consolidated his swings in the middle part of the plate where he’s likely to make better contact, particularly the lower-middle part of the zone. He has also laid off the inside pitch more often, especially low and in, and shifted those swings to cover the outside part of the plate. His increase in swings off the outside corner have also increased. Trading in swings at pitches off the inside corner for those off the outside corner may be the key to his increase in contact against pitches outside the strike zone.

Torres may have also made some progress on the defensive side of the ball. In 152 innings at shortstop in 2018, Torres had zero defensive runs saved and a -2.6 ultimate zone rating (UZR, a statistic that estimates the number of runs a player as saved or allowed on defense) for a -21.5 ultimate zone rating per 150 games played (UZR/150). In more than four times as many innings at short this season (636.2 innings), Torres has posted zero defensive runs saved and -2.0 UZR and -4.9 UZR/150, a big improvement over 2018. After 915.2 innings at second in 2018, Torres put up negative-one defensive runs saved, a -7.7 UZR, and -16.7 UZR/150. Four-hundred and forty-three innings there in 2019 have yielded negative-four defensive runs saved, a UZR of -2.5, and UZR/150 of -11.6, showing some mixed results for Torres. Advanced defensive metrics are still not as exact as we’d like them to be. Regardless, despite some potential improvement, defensive metrics still don’t identify Torres as a plus defender.

In addition to his overall production in almost two full seasons, the Yankees have to be thrilled that their twenty-two year old middle infielder has shown the ability to make adjustments and improve at the major league level. With the 2019 regular season nearing its conclusion, it makes some sense to take stock of what Torres has accomplished so far and what it means for him and the Yankees moving forward.

Comparing Torres’ performance to those of players who have come before him can give us an idea of what to expect from Gleyber in the future. Given that the Yankees will control Torres through the 2024 season with an extension, there seem to be three questions to answer: what can we expect from Torres in 2020, what can we expect from Torres from 2020 through 2024 (which will take him from his age 23 to age 27 season), and what can we expect from Torres in his career.

Torres has been an average fielder at best but more likely a slightly below average to below average fielder in 2018 and 2019, albeit at two premium defensive positions. To date, his value has largely come from his offensive ability. Entering Friday night’s game against Boston, in his age 21 and age 22 seasons, Torres has an average 125 wRC+. Below is a list of players who had an average wRC+ between 115 and 135 in their age 21 and 22 seasons (minimum 800 plate appearances), their wRC+ in their age 23 season, their average wRC+ from their age 23 to their age 27 seasons (weighted by number of plate appearances), and their average wRC+ in their careers.

Cody Bellinger is not fully through his age 23 season, but he’s included here as an extra data point for the age 23 numbers since his age 23 season is substantially complete. Christian Yelich is also currently in his age 27 season, but he’s been included in the age 23 to age 27 group for the same reason.

Based on the above player comparisons, the future is a pretty rosy picture for Gleyber Torres. Three hall of famers in Eddie Murray, Tim Raines, and Cal Ripken, Jr. and Alex Rodriguez and Scott Rolen, who should be Hall of Famers, as well as players like Darryl Strawberry, David Wright, and Grady Sizemore, whose careers were on Hall of Fame trajectories before being curtailed for various reasons. We can likely expect Gleyber to be somewhere between thirty to forty percent better than average at the plate next season, the same over the next five seasons, and about twenty-five to thirty percent better than average over the course of his career. For a middle infielder, that’s exceptional. If you want to dream on Torres a bit, there are certainly some names on this list that provide significant upside given what Torres has done as a twenty-one and twenty-two year old hitter.

Prior to Friday’s game against the Red Sox, according to FanGraphs’ version of Wins Above Replacement (fWAR), Gleyber Torres has recorded a combined 5.6 fWAR in his age 21 and 22 seasons. Dan Szymborski’s projection system ZiPS projects Torres for 0.4 fWAR for the rest of the 2019 season, which would give him a total of 6.0 fWAR in his age 21 and age 22 seasons. To give us a picture of what Torres’ future overall production might look like based on his performance as a twenty-one and twenty-two year old, below is a list of players who, since the start of free agency in 1977, accumulated between 4.0 and 8.0 total fWAR in their age 21 and 22 seasons with no more than 10.0 defensive runs above average total. Given Torres’ average to below average defense, the limit on defensive runs above average is meant to match Torres with players who have not derived a significant portion of their value from their play in the field.

You definitely feel good about Gleyber Torres’ future when looking at this group. Hall of Famers Raines, Murray, Alan Trammell, and Roberto Alomar with future Hall of Famers Miguel Cabrera and Adrian Beltre, and Rolen again. It also includes current stars Yelich, Betts, Bellinger, and Xander Bogaerts. When all of these players careers are finished, you could conceivably see half of them in Cooperstown, so it’s not surprising to see the kind of numbers you might be able to expect from Torres: between 4 and 5 fWAR next season, around 20 over the next five seasons, and around 50 in his career. And that’s about the 50th percentile outcome. A note on Miguel Cabrera: his career is not over yet, but it is at a point where he’s likely not going to accumulate much more value, so his career statistics have been included to give us more data.

Now, you might point out that a lot of these players played or play different positions than Torres does. Here’s a quick look at the list and numbers if we get rid of the first basemen and outfielders.

This is a list of infielders that you definitely want to be on. Half of the list is made up of Hall of Fame caliber players and the rest were or are, for the most part, very competent major leaguers. The average and median fWAR numbers are still outstanding.

According to FanGraphs, Torres has -8.8 defensive runs above average in his career. The last group of players was selected by looking at players who accumulated 10.0 or less defensive runs above average in their age 21 and age 22 seasons. What if we decrease that to 0.0 defensive runs above average?

There’s a slight dip in the numbers as the group becomes less productive as fielders, but that’s probably expected. The decrease is sharpest in career WAR, likely due to the fact that many of these players, who were not great defenders to begin with, had to move down the defensive spectrum to first base or corner outfield spots as they aged. Regardless, this group still provides a very favorable forecast for Torres.

Gleyber’s age 21 and age 22 seasons also happen to be his first two seasons in the league, and you can probably tell where this is going. Using Baseball Reference’s version of WAR (bWAR), let’s see what we find when comparing Torres’ first two years in the show to the freshman and sophomore campaigns of other players.

According to Baseball Reference, entering Friday night’s game against the Red Sox, Torres has accumulated 6.3 total bWAR in his first two seasons. Even though the fWAR and bWAR are slightly different (they use different defensive metrics to measure defensive value), we’ll add the 0.4 WAR that ZiPS projects Torres adding over the rest of 2019 for a total of 6.7 bWAR. Again, we’ll want to limit Torres’ comps to ensure we don’t include players who derive a lot of value from their defense. Torres has accumulated a defensive wins above replacement component of 0.7 in his first two seasons. The group of players below are those who accumulated a bWAR between 4.7 and 8.7 with a defensive wins above replacement component between 1.7 and -0.3 in their first two years in the show (minimum 800 plate appearances) since 1977.

This is an interesting group. It’s punctuated by two of the most elite talents to ever play the game in Rickey Henderson and Ken Griffey, Jr. at the top and peppered with some of the biggest names in the sport right now: Yelich, Giancarlo Stanton, Anthony Rendon, Bryce Harper, Bellinger, Alex Bregman, and Corey Seager. The numbers are still great and very much in line with what we’ve seen: a bWAR between 4 and 5 next season is likely, around 19 bWAR over the next five seasons, and a really good shot at a career bWAR somewhere in the 40s. Let’s whittle this list down to just the infielders and see what we get.

Corey Seager7.75.7N/AN/A

This group admittedly gets down to a pretty small sample, but it’s still probably somewhat useful, especially since the numbers we get are very much aligned with those that we’ve seen with the other player groups. The bottom line seems to be that, when comparing his performance to the performances of past players, Gleyber Torres’ future looks incredibly bright any way you slice it.

ZiPS appears to agree. Prior to the season, ZiPS projected Torres for 3.0 fWAR in 2019 (which he’s already surpassed), 4.2 fWAR in 2020, and 4.6 fWAR in 2021. About two weeks before the trade deadline, in their annual Trade Value series, FanGraphs ranked Torres as the twelfth most valuable player in all of baseball in terms of trade value and projected that he would accumulate 4.5 fWAR in 2020, 4.9 fWAR in 2021, 5.2 fWAR in 2022, 5.1 fWAR in 2023, and 4.8 fWAR in 2024 for a total of 24.5 fWAR from 2020 to 2024. Those numbers compare well with what our analysis found and are actually slightly better than that.

The surplus value is likely due to a component of the ZiPS projection system that incorporates Torres’ prospect grades. Baseball players are graded on their various tools on a 20 to 80 scale. Torres’ grades from before the 2018 season are stellar.

HitGame PowerRaw PowerSpeedFieldThrowFuture Value

The number before the slash is the player’s current grade at the time he’s scouted, and the number after is his projected grade once he’s fully developed. Future Value is the player’s overall grade. Players almost never receive 80 grades. As you can see, Torres doesn’t really have any standout tools, but he receives above-average grades across the board. Torres’ Future Value grade ranked him as the twelfth-best prospect prior to the 2018 season according to FanGraphs. Given those healthy grades, you can probably expect Torres’ production to skew closer to the top of the groups listed above as his career progresses.

The player groups above definitely include some cautionary tales (see: Rocco Baldelli). The careers of athletes are often more fragile than we realize and want to admit. That being the case, it’s important to enjoy what Torres is doing right now and not take it for granted. But it’s also exciting to think about having the opportunity to witness the entire career of what could be a generational talent. Who knows? In eighteen years, you could be watching another moment like this.

Aaron Judge Turns It Around

The New York Yankees have weathered more than their fair share of adversity this season. Thanks to a multitude of successful player development initiatives throughout the organization, the depth of the Yankees’ roster has allowed them to withstand the onslaught of injuries wrought by 2019. Despite their resilience, as the Bombers continue their march to capture the franchise’s twenty-eighth World Series title, the one thing it’s hard to envision them climbing to the top of the mountain without is a healthy and effective Aaron Judge.

That being the case, Judge’s recent slump was certainly cause for consternation. In twenty-one games from July 25th through August 15th, Judge slashed .148/.266/.235 for a .228 wOBA and 35 wRC+. In 94 plate appearances, he hit just one home run, four doubles, and walked twelve times against thirty-one strikeouts.

On April 20th, Judge injured his left oblique on a swing and missed time from April 21st until his return to the lineup two months later on June 21st. Many feared this most recent slump was the manifestation of lingering effects from the oblique injury. The Yankees’ right fielder maintained that he was healthy, and his numbers in the month after he returned seem to support that assertion. Judge hit .330/.460/.571 from June 21st to July 24th with a .429 wOBA and 171 wRC+. Those don’t look like the numbers of a player who came off the IL too quickly. Judge did come back with one noticeable change, however.

Below is a video of Judge in his first plate appearance of the season on March 28th against the Baltimore Orioles.

For good measure, here’s a freeze frame of his batting stance.

His hands are held high and close to his head with only the bottom hand being visible from this angle. As for his lower half, Judge is only slightly open in his stance here. If you’re an avid Yankees fan or just an Aaron Judge enthusiast, you may remember that the twenty-seven year old was experimenting by using no leg kick in two strike counts early this season in an effort to make more contact. Instead, he was lifting only his left heel off the ground during his load and placing it back down as he began to shift his weight forward. Here’s an example of that two strike approach on March 30th against the O’s.

By April 6th, after not hitting a homer in his first seven games of the season, Judge had abandoned that approach, perhaps in an effort to regain some of his hallmark power.

Here’s another snapshot of Judge’s revamped stance to accentuate the differences.

Judge’s hands are farther away from his body, and his bat is angled more vertically and tilted forward as his top hand has appeared from behind his helmet. He also looks slightly more open in his stance as more of his right knee and leg have become visible. If Judge was seeking more power with these adjustments, it worked. He hit five homers in thirteen games from April 6th through April 20th before injuring his oblique.

When Judge returned from the IL, there was some variation in his batting stance in the first few games back, but he eventually settled on the stance he used against Clayton Richard and the Toronto Blue Jays on June 25th.

Judge’s hands are much lower and even farther away from his body, and he’s as open as we’ve seen him in 2019. As noted above, these changes worked initially, as Judge had success in his first month off the IL. But eventually, they began to present issues.

Even in the at bat against Richard, you can see how much Judge’s hands have to work to get into a hitting position during his load. Against an 81 mph slider on the outside part of the plate, that may not matter much. But against fastballs on the inner part of the plate, that could get you into trouble if your timing isn’t right.

During Judge’s slump, he struggled to get the ball in the air. From July 25th to August 15th, his ground ball rate was 48%, almost ten percent higher than his 38.5% career mark and seven percent higher than his overall 41.2% ground ball rate during the 2019 season. Judge saw his ground ball rate start to increase when he came back from the IL in June, corresponding with the change in his batting stance. The following table shows a breakdown of his batted ball profile in three different periods this season.

Date RangeGB%LD%FB%
3/28 – 4/2039.6%31.3%29.2%
6/21 – 7/2443.9%28.1%28.1%
7/25 – 8/1548.0%24.0%28.0

Judge’s ground ball rate trended upward, his line drive rate trended downward, and his fly ball rate ticked down slightly. Digging deeper, in addition to hitting the ball on the ground more often, we can see that Judge was also making less solid contact during his slump. According to Statcast, his average exit velocity of 93.4 mph from July 25th through August 15th was almost two miles per hour lower than his career 95.2 mph average and more than three miles per hour lower than his 96.5 mph 2019 average. The trend was even more pronounced when Judge was pulling the baseball. Below are Statcast numbers for the same three periods above on Judge’s pulled batted balls.

Date RangeExit VelocityLaunch AnglewOBAxwOBA
3/28 – 4/20101.2 mph1.1 degrees.273.523
6/21 – 7/2497.5 mph-7.0 degrees.470.427
7/25 – 8/1590.3 mph-7.4 degrees.300.323

The drastic decrease in launch angle began when Judge returned from the IL. Still making solid contact, he was able to salvage many of those balls to the pull side. Predictably, as Judge’s exit velocity on pulled batted balls dipped, so did his offensive production. During his downturn, Judge seemed to have particular trouble handling fastballs, which he’s typically punished throughout his career. The table below shows his numbers against four-seamers, two-seamers, and sinkers as categorized by Statcast (cutters have been excluded as some pitchers use cutters more like sliders than more traditional fastballs).

Date RangeExit VelocityLaunch AnglewOBAxwOBA

6/21 – 7/24100.4 mph6.6 degrees.486.442
7/25 – 8/1594.5 mph5.4 degrees.232.307

Judge’s drop in production was even more pronounced when pulling fastballs (again, four-seamers, two-seamers, and sinkers).

Date RangeExit VelocityLaunch AnglewOBAxwOBA
3/28 – 4/20100.3 mph8.5 degrees.438.590
6/21 – 7/2499.6 mph-12.9 degrees.468.401
7/25 – 8/1589.3 mph-13.4 degrees.194.192

With such a low average launch angle, Judge couldn’t afford the more than 10 mph decrease in exit velocity. It appears that Judge was late getting around on fastballs and having trouble squaring them up during his slump. Here he is facing Boston Red Sox starter Rick Porcello on July 25th.

Judge takes on Eduardo Rodriguez on August 2nd.

And Darwinzon Hernandez on August 4th.

In the three videos above as with the clip against Richard, you can see how far Judge’s hands have to go before he can start to attack each pitch. If Judge’s timing is off, that extra movement can make it more difficult to meet an inside fastball out in front of the plate where it can be pulled in the air to left field. Additionally, a more complicated setup at the plate always opens up the possibility for more to go wrong with your swing. By introducing more movement into his mechanics, Judge may have found it more difficult to barrel the ball up consistently.

Above are attempts to capture Judge at the point of contact in each of the three clips against Porcello, Rodriguez, and Hernandez. Judge’s right elbow is absolutely pinned to his right hip as he’s late on the inside fastball, unable to fully extend his arms at contact. Without getting his arms extended, Judge can’t catch the ball out in front of the plate, robbing him of his prodigious power and preventing him from getting the ball in the air to the pull side. Judge also fails to get the barrel of the bat on all three pitches.

On August 16th, Aaron Judge made a change.

Facing Cleveland Indians rookie Aaron Civale, Judge’s hands are almost exactly where they were when he started the season: held high with his top hand disappearing behind his helmet and the bat angled much more horizontally with no forward tilt. Judge remains significantly open in his stance on the 16th but would come almost back to even by August 21st against Mike Fiers and the Oakland Athletics.

Judge has seen immediate results. From August 16th through August 26th, Judge has slashed .351/.385/.757 with a .405 ISO for a .461 wOBA and 192 wRC+. To display the difference, here’s Judge turning on a 95 mph four-seam fastball on the inside corner from Brad Hand on August 18th for a 100.6 mph double over the head of left fielder Oscar Mercado.

On August 21st, he ropes a 103.1 mph worm killer right at Matt Chapman on a 90 mph four-seamer on the inside part of the plate from Fiers.

Let’s take a look at Judge at the point of contact on both swings.

In each picture, you can see daylight between Judge’s back elbow and right hip, evidence that he’s more extended, which has led to harder contact and more lift for the righty slugger. He also gets both pitches on the barrel, which will always lead to better contact.

Below is the table from above showing Judge’s numbers when pulling fastballs including his latest hot streak starting on August 16th. He’s back to crushing fastballs and is also getting them in the air, where his power is at its most dangerous.

Date RangeExit VelocityLaunch AnglewOBAxwOBA

8/16 – 8/26103.7 mph11.7 degrees.586.830

Those trends are not isolated to pulled fastballs either, supporting the idea that Judge’s new stance has not only improved his timing but helped him square up pitches more consistently. Here are his Statcast metrics against that fastball pitch grouping generally.

7/25 – 8/1594.5 mph5.4 degrees.232.307

Since making his latest adjustment, Judge has been pulling the ball with more authority and in the air more frequently on all pitches, which you can see in his numbers when pulling the ball on all pitch types below.

Judge’s improved timing and ability to get the ball on the barrel has improved his overall numbers as well. Since August 16th, his average exit velocity on batted balls is 95.5 mph and his average launch angle is 15.4 degrees, leading to a .498 wOBA and a .508 xwOBA. According to data available at FanGraphs, 66.7% of his batted balls during that span have been categorized as hard hit balls. His batted ball profile shows major changes in his ability to get the ball in the air and to his pull side.

Judge has played only nine games and accumulated 39 plate appearances since August 16th, but it certainly appears that his adjustment at the plate has finally gotten him right after an extended slump. The Yankees will need this version of Aaron Judge if they’re going to make a run in the 2019 postseason. Here’s one last clip from August 20th where Joakim Soria serves one up to Judge, who can punctuate this article much better than I ever could.

Talking The Tauch

You probably didn’t pay much attention or even notice when the New York Yankees acquired twenty-eight year old outfielder Mike Tauchman from the Colorado Rockies in exchange for pitching prospect Phillip Diehl towards the end of spring training on March 23rd. Who could blame you? Tauchman’s major league resumé to that point was ugly: a .153/.265/.203 slash line in 69 plate appearances over 52 games for the Rockies.

From 2013 to 2016 in the Rockies farm system, Tauchman hadn’t shown much in his age 22 to age 25 seasons. He displayed a decent hit tool but didn’t flash much power, combining for only eight home runs across four minor league seasons. If Tauchman wanted to crack Colorado’s major league roster, he needed to make a change.

Prior to the 2017 season, as reported by the New York Times’ James Wagner, Tauchman worked with Justin Stone, a hitting instructor at Chicago-based Elite Baseball Training. With three-dimensional sensors and plates that measure force, Stone, who was hired as a hitting consultant by the Chicago Cubs in 2018, used biomechanics to help Tauchman improve his swing. Stone and Tauchman found that the former Rockie was transferring energy inefficiently from his lower half to his upper half. In scientific terms, Tauchman’s kinetic chain, or the sequence of movements that make up his swing, was off. With Stone’s help, Tauchman learned to use his lower half better when starting his swing, enhancing the transfer of energy up the kinetic chain.

The results were undeniable. Still in AAA, Tauchman improved his wOBA from .322 in 2016 to .399 in 2017 and .420 in 2018. His 139 wRC+ was good for the eight-best mark in AAA in 2017. In 2018, his 153 wRC+ was fourth-best, just behind fellow 2019 breakouts Daniel Vogelbach and J.D. Davis as well as Astros top prospect Kyle Tucker. Tauchman’s power had definitely increased: he tripled his career home run mark with sixteen homers in 2017 and swatted another twenty in 2018. The Yankees front office took notice and was intrigued enough by Tauchman’s minor league success to add him as a depth piece just before the 2019 season.

Tauchman’s rise has continued in 2019. In 71 games, he’s posted a .381 wOBA and 138 wRC+. That wRC+ ranks Tauchman twenty-ninth among 309 players with 200 or more plate appearances in 2019, just ahead of Josh Bell, Jose Altuve, and Anthony Rizzo. Tauchman’s done more than just impress with the bat in 2019. According to FanGraphs, he’s created 1.4 runs on the basepaths this season.

Tauchman has also shined with the glove in 2019. He’s played 559.2 innings in the outfield for the Yanks: 363 in left, 74.2 in center, and 122 in right. Tauchman has been above average defensively in all three spots and amassed a stellar fourteen defensive runs saved, which ranks him sixth among all outfielders with at least 500 innings played. To give you a sense of how good Tauchman has been defensively, he’s just two defensive runs saved behind the Tampa Bay Rays’ Kevin Kiermaier in almost three hundred less innings played.

Statcast numbers available at Baseball Savant agree that Tauchman has been outstanding in the field this season. Tauchman ranks tenth among ninety-five qualified outfielders with seven outs above average this season. Using the exit velocity and launch angle of the batted balls hit in Tauchman’s direction in 2019, Statcast calculates that 85% of those batted balls should have been converted into outs. Tauchman has caught 91% of those balls, good for the second-best catch percentage added in the league at 6% behind only Kiermaier’s 7%. Statcast’s Outfielder Jump metrics also rank Tauchman above average at twenty-seventh among the 105 qualifying outfielders.

Tauchman’s all-around game has contributed 3.4 bWAR in just 71 games played for the Bombers in 2019. However, there are some warning signs that his offensive breakout might not be sustainable. First, there’s a discrepancy between Tauchman’s .381 wOBA and his expected wOBA as calculated by Statcast based on the exit velocity and launch angle of his batted balls. His xwOBA is a mere .324, suggesting that luck has played a large part in Tauchman’s offensive success. Additionally, his .353 BABIP is fifty-four points above the league average .299 BABIP. With a pedestrian average exit velocity of 88.8 miles per hour, it’s likely that Tauchman will see his BABIP decrease and his offensive numbers regress somewhat. That said, according to Baseball Savant, Tauchman owns a 38.4% sweet spot percentage in 2019, which ranks him seventy-first of 436 qualifying hitters. Sweet spot percentage tallies the percentage of balls a batter hits in the ideal launch angle range between eight and thirty-two degrees. Since 2015, batted balls in the sweet spot have led to an average BABIP of .514 and average wOBA of .707.

There’s more to combat the assertion that Tauchman’s offensive breakout is just a mirage. Tauchman’s season has truly been a tale of two halves. The table below helps tell the story.

3/30 – 7/6.31088.0 mph7.8 degrees0.285.31030.2%
7/11 – 8/17.47289.5 mph16.3 degrees0.369.39719.3%

Tauchman’s actual wOBA is still outstripping his xwOBA by quite a bit over the last month, but his .369 xwOBA is nothing to sneeze at: it’s good for fifty-seventh among the 344 hitters with at least fifty plate appearances from July 11th through August 17th. The increase in his launch angle shows that he’s lifting the ball a lot more and that’s borne out in his batted ball profile as well.

3/30 – 7/653.3%16.0%30.7%
7/11 – 8/1731.0%31.0%38.0%

Tauchman’s ground ball rate has dropped dramatically in the second half, and his fly ball rate has increased by a significant amount. His 31.0% line drive rate is almost certainly unsustainable (Whit Merrifield of the Kansas City Royals currently leads the league at 29.7%) and has likely driven much of Tauchman’s success, but given the sweet spot percentage mentioned above, he may be predisposed to hit line drives more frequently than the typical hitter. As expected given his line drive rate in the second half, Tauchman has been hitting the ball harder more often.

7/11 – 8/179.7%51.4%38.9%

A more refined pitch selection appears to be what’s led to Tauchman’s offensive breakout over the last month.

Tauchman had already displayed excellent plate discipline in the first half with a chase rate that ranked forty-second among 437 hitters with at least fifty plate appearances. He’s improved upon that skill in the second half, as he’s swinging less overall, chasing less frequently, and swinging less often in the strike zone. His second half swing rate ranks thirty-third lowest among 345 hitters with at least fifty plate appearances, and his chase rate ranks twentieth among the same group. His even more patient approach after the All-Star break has led to more contact: he’s increased his contact rate by almost 6% and decreased his swinging strike rate by 3.2%. Below are his overall swing percentage heat maps from the first and second halves of the season.

Tauchman has really concentrated his swings in the middle of the zone, especially the inner-middle part of the plate, swinging most often in the upper-middle part of the zone. He’s also laying off pitches low and away and above the zone a lot more frequently. Swinging at pitches higher in the strike zone and staying off that low and away pitch probably has a lot to do with the reduction in his ground ball rate. You can see the same trend against four-seam fastballs, which Tauchman is seeing 42.1% of the time in 2019.

It’s most likely that Tauchman won’t be able to sustain all of his offensive breakout over the last month. Maintaining a near .400 BABIP is unheard of and Statcast shows that Tauchman has definitely been the beneficiary of some good luck. Even when regression comes for Tauchman, however, there appears to be enough to believe that he’ll retain some of that breakout. He has shown elite plate discipline and an above-average ability to put the bat on the ball. Those attributes will serve any hitter well. If he’s able to keep enough of his batted balls in the air, given his above-average base running and excellent defense, Tauchman has shown the tools to continue to be an above-average regular moving forward.
