Zack Britton bought himself an Edgertronic earlier this month. He’s pondering purchasing a Rapsodo, as well. The Yankees southpaw boasts a 2.57 ERA — and MLB’s highest ground-ball rate, to boot — but that doesn’t mean he’s satisfied. Once the offseason rolls around, Britton plans to fine-tune his arsenal even more.

If you’re a hitter chagrined by this news, blame his nerdiest teammate.

“I bought all the [Edgertronic] equipment, and wired it up in my house,” Britton told me yesterday. “Talking with Adam Ottavino about what he’s been doing the last two off-seasons is what really piqued my interest. It’s a way to keep up with how we’re being evaluated now, and it allows us to make adjustments faster.”

While a primary driver, Ottavino’s influence wasn’t the sole selling point. Britton hasn’t had a chance to put his new purchase to use, but the 31-year-old former Oriole has thrown in front of an Edgertronic before.

“The Yankees have high-speed cameras at the Stadium,” explained Britton. “I’ve noticed differences with both my breaking ball and my sinker. I can see where my hand position is when I throw a good pitch. Rather than just feeling my way through an adjustment, I can get instant feedback on the adjustments I need to make.”

Britton had the winter months in mind when he went shopping. While details still need to be worked out, the plan is to link his Edgertronic — and perhaps a Rapsodo — with ones used by the Yankees.

“We can communicate back and forth during the offseason,” said Britton. “[Pitching coach] Larry Rothschild can see the numbers and know the things I’m doing. And if there’s anything they want to see, I can try it and then send them the data. We have the technology to where we can do that.” Read the rest of this entry »

Below are some changes we made to The BOARD in the past week, with our reasons for doing so. All hail the BOARD.

Moved Up

Ronny Mauricio, SS, New York Mets:
We got some immediate feedback on Monday’s sweeping update, which included more industry interest in Mauricio. The average major league swinging strike rate is 11%. Mauricio has a 12% swinging strike rate, and is a switch-hitting, 6-foot-4 teenager facing full-season pitching. It’s common for lanky teenagers to struggle with contact as they grow into their frames, but Mauricio hasn’t had that issue so far.

Oneil Cruz, SS, Pittsburgh Pirates:
One of us was sent Cruz’s minor league exit velocities and they’re shockingly close to what Yordan Alvarez’s have been in the big leagues. Of course, there remains great uncertainty about where Cruz will end up on defense, and hitters this size (Cruz is listed at 6-foot-7) are swing and miss risks, but this is a freakish, elite power-hitting talent.

Marco Luciano, SS, San Francisco Giants:
This guy has No. 1 overall prospect potential as a shortstop with 70 or better raw power. He belongs up near Bobby Witt, who is older but might also be a plus shortstop while we’re still not sure if Luciano will stay there.

George Valera, OF, Cleveland Indians:
Valera is torching the Penn League at 18 and a half years old, and we’re not sure any high school hitter in this year’s draft class would be able to do it. His defensive instincts give him a shot to stay in center field despite middling raw speed, and his swing should allow him to get to all of his raw power, so it becomes less important that his body is projectable. He would have been fifth on our 2019 draft board were he playing at a high school somewhere in the U.S., so he’s now slotted in the between JJ Bleday and C.J. Abrams on our overall list.

Terrance Gore’s job is to come into games as a pinch-runner and steal bases. He might want to do more, but at the major league level, baserunning is his calling. Entering this season, Gore had totaled one hit, one walk, and one HBP in his career, including the postseason. Despite almost never reaching base, Gore has 32 career steals and had been caught just five teams before this year. Of his 61 appearances before 2019, 55 have come in September, when rosters are larger, or in the playoffs, when fewer pitchers are required. The Royals gave Gore a shot at slightly more playing time this year, but ultimately designated him for assignment. After he cleared waivers, he was traded to the New York Yankees for cash considerations, so Gore might once again loom large in September and the postseason.

What’s weird about Gore this season is that his stolen base numbers aren’t very good. He’s 13-of-18 on steals, and while that might be just fine for most players, when stealing bases is a huge part of your job, it’s really not that great. His sprint speed is one of the best in the game, so it’s pretty curious that he’s been caught stealing five times. Maybe teams are onto him, though that never stopped him before. Let’s take a closer look.

Gore’s first caught stealing happened on April 17 in the eighth inning. He didn’t get caught stealing so much as he got caught leaning as the photo shows below.

Gore’s next misadventure on the basepaths happened against the Yankees on April 21. Second one same as the first. Read the rest of this entry »

Chris Stewart was never supposed to be a catcher.

In 1999, Stewart was slated to be his Moreno Valley, CA high school’s starting shortstop as a junior. But after the starting catcher quit the baseball team to join cheerleading, and the backup missed months with appendicitis, Stewart was thrust into the role.

“The coach, with no catchers left, comes up to me and says, ‘Hey, do you want to catch?’” Stewart recalls. “I tell him, ‘No. Why would I want all the bumps and bruises and bad knees? This sounds like a ridiculous idea.’ He’s like, ‘Well, you’re all we have left, so you’re catching.’” Read the rest of this entry »

Through the first month of the season, it looked like James Paxton was going to build on his breakout 2018 season and elevate himself into the upper echelons of the pitching ranks. Through May 3, he had posted a 3.11 ERA backed by a 2.59 FIP and a ridiculous 33.6% strikeout rate. On May 3, Paxton exited his start with a knee injury and wound up missing four weeks of play, and since his return from the injured list, he just hasn’t been the same.

In his eight starts since May 29, his FIP has shot up to 4.65 and his strikeout rate has fallen to 24.7%. A vintage 11-strikeout performance in his last start on July 7 is propping up that strikeout rate, too; he struck out just three batters in each of his two previous starts before that. The league average strikeout rate for a starter is 22% so complaining about Paxton’s dip in results feels a little like picking nits. It would be easy to chalk up his post-IL results to the lingering effects of the knee injury or just a string of bad luck. But a deeper look into his pitch repertoire reveals some concerning trends.

Back in early May, Sung Min Kim wrote an article detailing the changes Paxton had made to his pitch mix. In short, Paxton “basically swapped the usage rates of his cut fastball and curveball.” And why wouldn’t he want to throw his cutter more often? He generated a ridiculous number of whiffs with the pitch last year (37.2% whiff rate) and batters simply could not square it up when they did make contact with it (6.5% barrel rate). But the effectiveness of the pitch has waned with greater exposure.

In the past, it’s been a put-away pitch Paxton turned to when he was ahead in the count. He would use his fastball and curveball to get ahead and then earn a strikeout with a well placed cutter. Because he’s throwing his cutter more often this season, he’s had to use it earlier in at-bats. There are only so many two-strike counts to throw it in, so some of those extra cutters have come when the count is in the batter’s favor. Here’s what Paxton’s cutter usage has looked like by count over the last four seasons:

Not only is he throwing it more often earlier in the count, he’s also throwing it less often when he does get ahead. Trying to steal a strike with his cutter early in an at-bat isn’t necessarily a bad thing — he used his curveball to do exactly that last year — but it becomes a problem when he can’t locate his cutter in the zone:

Paxton’s cutter is at it’s very best if he can locate it down and in against a right-handed batter, right over their back foot. That location takes the pitch out of the strike zone to get a swinging strike. But he’s actually spotted his cutter in the zone more often than you might expect. In years past, he’s thrown his cutter in the zone around 47% of the time, a touch below the league average zone rate for a cutter. Even though it feels high for a put-away pitch, it never really affected his ability to earn a swinging strike. This year, he’s locating his cutter in the zone around 35% of the time, the lowest zone rate of any cutter thrown more than 100 times:

He’s locating the pitch as though he was ahead in the count and looking for a whiff, but those pitch locations aren’t exactly ideal earlier in the count. Batters are content to just take a cutter when they hold the advantage, knowing that they’re likely to either whiff or it’ll end up out of the zone as a ball. So even though Paxton’s whiff per swing rate on his cutter is just as good as it has been in the past, because his overall swing rate on the pitch is down almost 10 points, his raw number of swinging strikes is down.

Since 2017, Paxton has added more than two inches of horizontal movement to his cutter. It’s possible that additional movement has affected his command of the pitch:

If he’s throwing his cutter the same way he did last year, aiming at a target that would locate the pitch in the zone, that extra horizontal movement could be carrying the pitch out of the zone despite his intent.

It’s also possible that batters are able to identify his cutter more easily this year. Paxton took a big step forward last year when he started to tunnel his high four-seam fastball with his curveball. But his cutter also benefited from that pitch tunnel as well:

Last year, Paxton’s fastball-cutter pitch tunnel was excellent. The perceived distance between the two pitches in sequence (PreMax) was well above average and they separated in flight (PreMax Time) just a few milliseconds before the tunnel point. Both measures have deteriorated a bit this year and it’s likely due to the location of these pitches in sequence. Paxton’s pitch tunnel works best when his cutter is located right at the bottom of the zone but not too low. THe average location of his cutter this year has given opposing batters a few extra milliseconds to identify whether a pitch is worth swinging at.

I can’t explain why Paxton has swapped the number of curveballs and cutters he throws this year. Maybe he’s lost the feel for his curveball. But the effectiveness of his secondary pitches has waned with the altered usage pattern. The solution is likely a little more complicated than just swapping back. He’s going to have to figure how to locate his cutter a little better, especially if he needs to use it earlier in counts to keep batters off his fastball.

Jim Bouton first made his mark as a star right-hander for the Yankees at the tail end of their 45-year dynasty, winning 39 games in the 1963-64 regular seasons (plus two more in a pair of World Series), and making one All-Star team (’63). Yet his second act — after he injured his arm, lost his fastball, and hung on to his career literally by his fingernails, trying to tame the knuckleball with the expansion Seattle Pilots — was far more interesting and impactful. Bouton began keeping notes chronicling his travails, which, with the help of editor (and fellow iconoclast) Leonard Shecter, became Ball Four. His candid, irreverent, and poignant “tell-some” account of his 1969 season with the Pilots, Triple-A Vancouver Mounties, and Houston Astros not only became a best seller, it revolutionized the coverage of athletes, and keyed a proliferation of inside-baseball books that went far beyond the diamond. Recognized in 1996 as the only sports book among the 159 titles selected for the New York Public Library Books of the Century, Ball Four brought Bouton enough fame and notoriety to last a lifetime. That lifetime ended on Wednesday, when Bouton, who was 80 years old and suffering from vascular dementia, passed away at his home in Great Barrington, Massachusetts.

With its candid glimpse into the lives of major league ballplayers — hard-drinking, skirt-chasing, amphetamine-popping athletes using four-letter words — as they attempted to cope with the pressures and the boredom of the game, Ball Four was raunchy and controversial. Set against a backdrop of social upheaval, the outsider Bouton often found himself at odds with his teammates regarding the war in Vietnam, race relations, politics, and the burgeoning union movement within the game, which would eventually challenge the Reserve Clause, leading to higher salaries and the right to free agency.

Amazingly, such an explosive exposé did not win Bouton many friends within baseball. Fellow players accused him of violating the sacred trust of the locker room. His ex-Yankees teammates were said to take it very hard, particularly Mickey Mantle, whose debauchery had previously been hidden from fans by writers who had sanitized heroes for public consumption. Bouton, whose major league career ended shortly after the book was published in 1970 (though he made a brief comeback with the Braves in 1978), was effectively blacklisted by the Yankees until 1998, after the tragic death of his daughter Laurie in an automobile accident prompted his son Michael to write an open letter to the New York Times, asking the team to help Bouton heal old wounds by inviting him to Old-Timers’ Day. They did, and Bouton was greeted with a warm ovation. His cap flew off on his first pitch, a signature from his playing days.

When excerpts of Ball Four first appeared in Look Magazine in the spring of 1970, MLB commissioner Bowie Kuhn tried to get Bouton to recant his claims and state that the book was fiction. “It was the perfect form of censorship,” the pitcher-turned-author recalled in 2010, on the occasion of the book’s 40th anniversary. “The publisher had only printed 5,000 copies on the grounds that nobody would want to read a book about the Seattle Pilots written by a washed-up knuckleball pitcher. Then the baseball Commissioner calls me in, and they have to print another 5,000 and then 50,000 and then 500,000 books…” Including 10th, 20th, and 30th anniversary editions with epilogues that created what MLB’s official historian John Thorn called “a candid, sometimes heartbreaking extended memoir without parallel in American literature,” Ball Four sold millions of copies worldwide.

Adam Ottavino has had a strange 2019. Last year, he reinvented his game in a single offseason. This year, he’s mostly sticking with what worked in 2018, and the results have been pretty good. Despite pitching in homer-happy Yankee Stadium, he’s posted a 1.80 ERA (39 ERA-), and his strikeout rate is a gaudy 32.2%. He easily could have been an All-Star, even if his FIP is a less-inspiring, if still good, 3.85. His walk rate, too, has spiked — to 15.8%, near a career high. It’s too early to say whether Ottavino will back up his breakout 2018 or regress closer to his FIP by season’s end.

What it’s not too early to say, however, is that watching Ottavino pitch this year is an absolute joy. His slider, which he throws more than 40% of the time, has always been his calling card, and it’s as fun as ever, taking a great liquid arc across the plate that can make you question physics. His fastball, a hard two-seamer that he uses more like a four-seam fastball, locating it high in the zone, is a delightful offset to the slider. His cutter — well, his cutter isn’t as fun to watch as the other two pitches, but it sits in between them in velocity and movement and helps disguise everything else. What’s so great about Ottavino, though, isn’t just his raw stuff. It’s the way he uses those pitches that is so fun, and this year, he’s using them to get called strikes by the bucketload.

When you picture a 2019 slider in your mind’s eye, you might picture Ottavino’s, or maybe Patrick Corbin’s. Big break, the batter desperately trying to adjust his swing to hit something that’s falling down and away from him, and the catcher blocking a bouncing ball to record a strikeout. Ottavino still has that pitch in his arsenal, of course. Take a look at him going right after noted slider-masher Lourdes Gurriel and coming out on top:

The New York Yankees are incredible. They control first place in a strong American League East division by seven games; our playoff odds project them as having an 88.3% chance of winning the division, with 16.2% odds to win the World Series. This, despite an astonishing volume of injuries suffered by key players over the first half of the season, a series of events that thrust bench bats and backups who once seemed somewhat redundant into the spotlight. DJ LeMahieu, for example, didn’t have a clear starting spot when the team signed him to a 2-year, $24 million contract over the offseason. But a week away from the All-Star break, he’s been the Yankees’ best player, and it isn’t particularly close.

At 3.6 WAR, LeMahieu is a full win better than the next-most valuable player on the roster. He leads his team in batting runs above average (20.8) and defensive runs above average (3.5). He is second in wRC+ (145) and wOBA (.389). He’s the AL’s leader in batting average (.345). The Yankees are an outstanding offensive team, ranking fourth in team wRC+ and hitting the fifth-most homers in baseball, despite the long absences of sluggers like Giancarlo Stanton, Aaron Judge, Miguel Andujar, Aaron Hicks, and Didi Gregorius. Yet, it is LeMahieu — he of the 94 career wRC+ and 61 total homers over nine seasons — who has served as the linchpin of the New York lineup.

LeMahieu has been popular around these parts for a while now. In early 2018, Travis Sawchik caught up with him to discuss his shift away from being an extreme opposite field hitter, and over this past offseason, Jeff Sullivan discussed his potential were he ever to unlock more power. This seems like a good time to check back in with LeMahieu, though, because he has spent the past few weeks setting the baseball world ablaze. Since going 3-for-5 against the Blue Jays on June 5, LeMahieu has hit .424/.467/.717, with six homers, eight walks, and 27 RBIs in 22 games. His production in that span gives him an absurd 213 wRC+ and 2.0 WAR, both of which lead the majors.

It’s been a long time since LeMahieu was this hot:

That previous spike came in August 2016, when LeMahieu rattled off a similarly torrid stretch. In 22 games from August 2-28, he hit .447/.544/.647 with four homers, 17 walks and just seven strikeouts. That happened to be his best year in the majors, as he finished with a .391 wOBA and 4.4 WAR as a member of the Colorado Rockies and won the NL batting title. Before that season, LeMahieu had always been a below average hitter; in the two seasons that followed, he was one again. Now, he’s back to being a revelation, and continues to show an ability to adapt.

One of the knocks against LeMahieu during his free agency was his predictably uncomfortable home/road splits. During his tenure with the Rockies, he recorded an OPS of .834 and a wRC+ of 96 at Coors Field, but had his OPS fall to .681 when he played on the road, with his wRC+ taking a corresponding dip to 84. That makes a good bit of sense. Because his low number of fly balls limits his power potential, LeMahieu’s offensive production relies upon him having a high BABIP, the way he did in 2016 when he hit .388 on balls in play. Coors’ spacious outfield will serve players like that well — between 2012 and 2018, three of the top four home BABIPs in baseball belonged to Rockies hitters, with LeMahieu ranking at the top of that list at .374. Away from Coors Field, his BABIP was .310. Skepticism over how valuable he could be when calling a different ballpark home was reasonable. This year, however, LeMahieu has done all he can to put that criticism to rest. At Yankee Stadium, he’s hitting a robust .335/.402/.555 with a BABIP of .357 and a wRC+ of 152 a tOPS+ of 108. His road numbers look pretty good too: .350/.375/.497, with a .385 BABIP and a 136 wRC+.

The matter of LeMahieu’s home/road splits wasn’t the only one he needed to address as a Yankee. He also needed to prove he could hit something other than a fastball. In 2018, LeMahieu was a solid fastball hitter, posting a wOBA of .356. That came honestly enough — from 2015 to 2018, only one hitter in baseball, Ben Revere, saw a higher percentage of fastballs than LeMahieu (65.8%). He struggled, however, against breaking and offspeed pitches, with wOBAs of .254 and .275 against them, respectively.

This year, opposing pitchers have begun to change the way they approach LeMahieu. Just 56% of the pitches he’s seen in 2019 have been fastballs, down 11% from a peak rate of 67% in 2017. Slider and cutter usage against him has gone up a combined 6.5% from just one year ago, and he’s seen about 2% more changeups and splitters. Added together, that’s a notable change, and in response to seeing a more balanced repertoire, LeMahieu has made himself into a more balanced hitter:

One of the keys to LeMahieu’s great 2016 season was his ability to get positive results out of just about any pitch thrown his way. With his resurgence in 2019, it’s no surprise he’s seeing similar results. LeMahieu has been one of the 10 best hitters in baseball against both the slider and the curve this year, after struggling with each of those pitches in the past. At the same time, he continues to hit fastballs well. In 2016, LeMahieu recorded a .412 wOBA against the fastball. In 2019, that number is .394. As you might imagine, striking this kind of balance isn’t easy. Across all of baseball, just two hitters have posted at least a wFB of 4.0, a wSL a 4.0, a wCB of 4.0, and a wCH of 3.0: LeMahieu, and former Rockies teammate Charlie Blackmon.

It’s easy to evaluate a recent free agent signee in the midst of an unsustainable hot streak and say a bunch of teams missed out on him. But LeMahieu makes the impulse difficult to resist. Just two teams have gotten at least LeMahieu’s 3.4 WAR out of their second basemen, and no team has gotten more value out of a position player free agent who signed this offseason:

With the return of Hicks and Judge, as well as their trade for Edwin Encarnacion, the Yankees are closer to full strength than they’ve been in a long time. But they still have a long way to go. Stanton and Cameron Maybin are likely out until at least August, while Andujar won’t return until 2020. Injuries persist on the pitching side. A deep postseason run remains very likely, but it will continue to require constant adjusting and refining for the team to reach its potential. Perhaps that makes LeMahieu the perfect player for the Yankees.

The lingering suspense over whether the Yankees could break the major league record for consecutive games with a home run, which they had tied at 27 on Monday night, lasted until Tuesday night’s sixth pitch from Blue Jays starter Clayton Richard to Yankees leadoff hitter DJ LeMahieu. Boom!

In the brief interval that it took this scribe to tweet about that record — admittedly, while juggling a beer and a scorebook in section 422 of Yankee Stadium — Aaron Judge homered as well. In fact, solo home runs accounted for the Yankees’ entire output in their 4-3 victory, with Gleyber Torres and Edwin Encarnacion joining the party, too. The latter even broke out the parrot against his old team for just the second time since departing in the winter of 2016-17, that while a hawk literally watched his dinger from atop the right field foul pole.

Here’s the Yankees’ new perch after Wednesday, when Didi Gregorius’ second-inning home run off Toronto’s Trent Thornton further extended the streak (LeMahieu added another one in the Yankees’ come-from-behind win as well):

It doesn’t take the eyesight of a hawk to note that 11 of those 13 seasons are from the post-1992 expansion era, which has featured at least one home run per team per game — a level previously topped only in 1987 — in all but five seasons (1993, and every year from 2010-14 except for ’12). Four of those seasons, including three of the top seven, are from the 2016-19 period, which, as I noted on Monday in relation to Justin Verlander’s performance, is the first four-year stretch with at least 1.1 home runs per team per game. This year’s 1.36 per game is the all-time high, 0.1 ahead of the previous high set just two seasons ago, an increase of 8.7%. It’s 0.21 home runs per game (18.8%) higher than last year, and 0.5 homers per game (58.4% higher) than in 2014, the year of the post-1992 low:

If we factor in the ever-increasing strikeout rates, the rise is even sharper. This year’s rate of home runs per batted ball — that is, HR/(AB-SO+SF) — is 5.31%, 0.49 points (10.1%) higher than the previous high in 2017, 0.86 points (19.3%) higher than last year, and 2.08 points (64.2%) higher than 2014.

I’ll get back to that momentarily, but it’s worth noting that when the Yankees’ streak began in late May, only three of the seven players who contributed the most home runs to last year’s record-setting total of 267 were active, namely Aaron Hicks (who tied for second on the team with 27 homers), the sixth-ranked Torres (24), and seventh-ranked Gary Sanchez (18). Since then, the 1-2 punch of Giancarlo Stanton (38) and Judge (27) has returned from lengthy stints on the injured list, and Gregorius (27) has returned from off-season Tommy John surgery. Miguel Andujar (27) is out for the remainder of the season due to surgery to repair a torn labrum, but on June 16, the team traded for Encarnacion, who currently leads the league in homers (24, including three as a Yankee).

All of which is to say that it’s been a mix of A- and B-list players who have not only propelled this particular Yankee streak but have helped the team out-homer all but three other teams, namely the Twins (149), Mariners (145), and Brewers (138):

Such are the Yankees’ power reserves that the acquisition of Encarnacion led to Frazier, who has hit a robust .283/.330/.513 (117 wRC+), being optioned to Triple-A Scranton/Wilkes-Barre, and remaining on the farm even as Stanton went back to the IL with a sprained posterior cruciate ligament in his right knee, the result of a baserunning mishap early in Tuesday night’s game. He’ll miss the upcoming London series against the Red Sox, and will be out for longer than the 10-day minimum. With or without Stanton, who has played just nine games this season, it’s not hard to imagine a more complete Yankees lineup overtaking the Twins in the home run department. But even if they don’t, the rather patchwork lineup has kept them on pace to eclipse last year’s total, which is a hint that the homer situation is simply getting silly.

League-wide, no individual is on pace to challenge Barry Bonds‘ single-season home run record of 73; Christian Yelich, who leads the majors with 29 homers, would finish with 62 if he were to keep hitting them at the same pace over the Brewers’ final 82 games as he has over his first 73 (he’s missed seven games with assorted aches and pains). However, with only five teams past the halfway point in their schedules heading into Thursday (the Mariners have played 84 games, the other four of those teams 82), a total of 56 players had reached the 15 homer plateau, meaning that they were on pace for 30 homers. The league-wide record for such players is 47, set in 2000. Four of the top five totals hail from the 1996-2001 stretch, with the fifth coming in 2017, when 41 players reached it. Similarly, 18 players have reached 20 homers, and are on pace for at least 40. The record for players with 40-homer seasons is 17, set in 1996, and we haven’t seen more than nine players do it in any Statcast-era season; there were nine in 2015, but just three last year. Yelich, Pete Alonso (27 homers through the Mets’ 81 games) and Cody Bellinger (26 homers through the Dodgers’ 82 games, including one on Wednesday) are on pace for at least 50 homers. Only in 1998 and 2001 did more than two players reach that plateau, with four apiece in both of those years, including the single-season record breakers, Mark McGwire and Barry Bonds.

Meanwhile, 14 of the majors’ 30 teams are on pace to set franchise records, with the top four surpassing last year’s Yankees:

All but three of the 30 teams are averaging at least one homer per game. Twenty-two teams are on pace for 200 homers, one fewer than in all of baseball prior to the 1994 players’ strike. Only in 2017, when 17 teams reached that plateau, have there even been as many as a dozen teams to do so. Eight teams are on pace for 250 homers, a level reached by just six teams ever prior to this year. The mind reels at these numbers.

While one can point to the general trend of batters making greater efforts to elevate the ball — whether to hit it over shifted infielders or not — it’s more accurate to call that an adaptation to the new reality. The scientific evidence again points to the ball itself as being the driving factor. Earlier this week at The Athletic, Dr. Meredith Wills published a follow-up to last year’s breakthrough article, which itself was a follow-up to MLB’s Home Run Committee report. That committee, led by Dr. Alan Nathan, professor emeritus of physics at the University of Illinois, had found that the recent home run spike was caused by a decrease in the ball’s aerodynamic drag, but found no physical difference in the balls that would explain the change.

Conducting her own measurements using digital calipers and disassembled baseballs, Wills concluded that post-2015 balls’ laces, which were an average of nine percent thicker than balls from the 2010-14 period, were producing less bulging at the seams, yielding a more spherically symmetric ball with less aerodynamic drag — thus allowing them to fly further.

For her latest study, Wills examined 39 balls from this season, which she found differed from the 2015-18 balls and even earlier ones. Most notably, she found “demonstrably lower” seams, only 54.6 percent ± 15.0 percent as high as those on balls from previous seasons. By measuring the coefficient of static friction, she also found that the leather on this year’s balls is relatively smoother, concluding, “the static friction for the 2019 balls is 27.6 percent lower, a statistically significant result demonstrating the leather covers are genuinely smoother.” She measured the bulging of the seams and found, “Not only were the 2019 balls virtually round, what bulging they did show was slightly negative, suggesting the seams might be slightly ‘nestled’ into the leather.” The significantly rounder balls, which have thinner laces than last year’s (more in line with 2000-14 samples) produce even less drag than before, and thus even more carry. Wills noted that both the seam and smoothness issues jibe with anecdotal reports from pitchers about difficulties in gripping this year’s balls, as voiced by players such as Sean Doolittle, Jon Lester, and Noah Syndergaard.

As for commissioner Rob Manfred’s recent suggestion that a better-centered pill (the core of the ball) is a factor in creating less drag, Wills was largely dismissive, writing, “[T]his is the most difficult result to produce without significant manufacturing changes, since existing techniques make it hard to keep the pill from being centered to begin with… Therefore, it seems unlikely that pill-centering would explain a sudden change in drag; at the very least, we would be remiss not to also examine other possible sources.”

All of Wills’ articles on the topic, which are behind a paywall, are worth reading, but it should suffice to say that there’s ample scientific evidence that the ball is carrying this. And how. Check out these numbers, which combine Statcast’s average distance measurements with those from our stat pages:

Fly balls are carrying an average of four feet further than last year, and eight feet further than in 2015. Add to that a general increase in fly ball rates and you have a recipe for significantly more homers. Perhaps too many homers. Combine that trend with the aforementioned strikeout trend and lower batting averages — though this year’s .251 is three points higher than last year, it’s in a virtual tie with 2014 for the second-lowest mark of the DH era, which began in 1973 — and the result is a greater percentage of runs being scored via homer than ever before. Here’s an historic look at what Joe Sheehan christened “the Guillen Number” a decade ago at Baseball Prospectus:

For a period of over two decades, from 1994-2014 — two decades that saw record home run rates, PED scandals, expansion, new ballparks galore — the rate of runs scored via homers was remarkably stable around 35%, never deviating more than two points in either direction. It hit 37.3% in 2015, and has climbed at a rate of about two points per year since, to heights previously unseen, and now, both statistically and aesthetically, the situation sticks out like a sore thumb. Ken Rosenthal called it “Bludgeon Ball” earlier this month, and I think the description fits. This is brute force baseball, and while it doesn’t lack for a certain amount of excitement, it’s very lacking in subtlety. When nearly half the league is on pace to set home run records, and the vast majority of teams are set to exceed totals that were once very rare, we’ve gone too far.

It’s time for MLB and Rawlings (which the league bought last year) to fix this. Wills noted that while Manfred has maintained that Rawlings hasn’t changed its manufacturing process or materials “in any meaningful way,” this may be an issue of semantics:

The Home Run Committee found that Rawlings regularly implements production improvements, including changes to the yarn (February 2014), the pill (March 2014, May 2015), the leather (June 2014, February 2017, August 2017) and the drying process (March 2016, February 2018). The Committee described these changes as “largely technical in nature and very unlikely to be in any way related to the (2017) home run increase.” That being the case, things like enhancing leather smoothness or drying baseballs more efficiently might not be considered “meaningful” to manufacturing.

While this may have been a reasonable attitude in the past, such enhancements now appear to have compounded, producing a more aerodynamic ball.

Wills recommended another committee report with the goal of using the information to tighten specifications, improve quality control and “determine further production improvements.” To these eyes — and I know I’m not alone — such improvement would include the restoration of some normalcy. When a player’s 40-homer season, or a team’s mountain of 200 homers, is no longer worthy of celebration, is as common as a garden weed, we’ve lost something. It’s worth searching for how to get that special something back.

Edwin Encarnacion is 36 years old now, but age hasn’t stopped him from mashing baseballs. Among qualified American League hitters, he ranks 12th in wRC+ (139), leads the league in home runs (21), and is fourth in isolated power (.290). He’s accrued 1.7 WAR, which is pretty good at this point of the season, especially given his subpar defense. Of course, nobody is employing Encarnacion for his glove.

When Seattle acquired Encarnacion this past offseason, everybody knew he’d be traded sooner rather than later. The Mariners are in the midst of a rebuild and are reportedly “trying to trade everyone” before the July 31 deadline. Encarnacion, with his age and contract, was an obvious candidate to be moved.

It only took until the middle of June for the Mariners to find a suitor. The Yankees now employ Edwin Encarnacion.

Yankees Get:

• 1B/3B/DH Edwin Encarnacion (though it’s likely he’ll primarily be a DH)

Mariners Get:

• RHP Juan Then

Let’s touch on the Mariners’ return first before talking about the big parrot in the room. Juan Then was actually a Mariners farmhand two years ago. The Yankees acquired Then (and minor league hurler JP Sears) during the 2017-18 offseason in exchange for Nick Rumbelow.

Then is only 19 years old and he’s still in rookie ball. Prior to this season, Eric Longenhagen and Kiley McDaniel ranked Then as the No. 31 prospect in New York’s system, noting that he is “advanced for his age” but has “middling stuff and physical projection.” It’s worth noting that Then seems to have developed a better fastball in the Yankees system. But again, it’s awfully hard to project a 19-year-old who hasn’t reached full-season ball. We know he’s a young arm of some promise, but the delta in his potential outcomes is very wide.

As an interesting side note, reports suggest that the Mariners chose to deal Encarnacion to the Yankees because New York was willing to absorb more money than other interested clubs. By prioritizing salary flexibility, Seattle’s move is somewhat reminiscent of how the Marlins handled the Giancarlo Stanton trade, in which the Yankees gave up significantly less player value to bring in another slugger because they were able to take on big money. It’s not ideal for rebuilding teams to prioritize monetary value over player return on transactions, but it is what it is. Money is a big part of how organizations operate, and sometimes you’re going to see deals like that. Read the rest of this entry »
