On Wednesday, Joey Votto officially announced his retirement from a major league career that spanned parts of 17 seasons, all with the Cincinnati Reds. He hit free agency for the first time last winter before signing a minor league contract with the Toronto Blue Jays, his hometown team. During his first spring training game with Toronto, he stepped on a bat and twisted his ankle, and it took him until June to get back into games. He eventually reached Triple-A at the start of this month but struggled there, hitting .143/.275/.214 with 22 strikeouts in 51 plate appearances with Buffalo.

“Toronto + Canada, I wanted to play in front of you,” Votto wrote on Instagram. “Sigh, I tried with all my heart to play for my people. I’m just not good anymore. Thank you for all the support during my attempt.”

“Anymore” is the key word there, because for the bulk of his career, Joey Votto banged. He retires with a .294/.409/.511 slash line, a 145 wRC+, 58.8 WAR, 356 home runs, and 2,135 hits. He made six All-Star teams, won the NL MVP award in 2010, and ranks 40th all-time in career MVP shares at 3.08.

I will be very surprised if Votto isn’t inducted into the Hall of Fame fairly quickly after he debuts on the ballot in four years. (He didn’t play in the majors this season, so for the purposes of eligibility, he retired after 2023.) Assuming he does, he’ll mainly get in on the basis of his tangible career accomplishments, with no controversy to counterbalance. My vote for him, so long as I haven’t prematurely shuffled off to eternity, will be based on his accomplishments as a player, but when it comes to Votto, his legacy is more than just his on-field performance.

As a baseball player, Votto was very much a 21st-century slugger, rather than the classic power hitter archetype. A phenomenally disciplined hitter, Votto swung at just 19% of pitches thrown to him outside the strike zone from 2012 to ’20 (using the Sports Info Solution data), second only to Alex Avila. It’s no coincidence that Votto was one of the most disciplined hitters around; you would be hard-pressed to find someone who doesn’t think of Votto as one of the game’s most thoughtful people. Whether hanging out at chess clubs, learning Spanish just to communicate better with teammates, or using his Players’ Weekend nickname to pay tribute to Canadian soldiers who died in World War I — by way of Canadian poet John McCrae’s famous poem, “In Flanders Fields” — he was always interesting, in the best possible way. Votto was a constant tinkerer of his swing and his approach at the plate, and when his career was on the definite downslope, he took the bold step of becoming more aggressive at the plate, a pretty big change for a player in his late 30s, squeezing out one last great offensive season in 2021 (36 homers, 140 wRC+).

Votto also spoke out about his experiences with grief and anxiety, back in 2009, when it was taboo for an athlete to talk publicly about their mental health. As Julie Kliegman reported in her recent book, Mind Game: An Inside Look at the Mental Health Playbook of Elite Athletes, players today are more open about their struggles with mental illness and more willing to seek the help that they need than they were 10-15 years ago; that’s because of stars like Votto and Zack Greinke, among others from across the sports landscape, who came forward at a time when mental-health conversations in sports were rare. This kind of thing has always resonated with me because my dad was severely psychologically affected by his experiences in Vietnam, and rather than being able to accept assistance — no matter how often and vigorously it was offered to him — he spent 25 years trying to drink away his memories, which he managed to do permanently in 1997. I’ll always have a very soft spot for someone who speaks up so that others can get help.

It’s bittersweet when a beloved player retires. It represents a sudden change in a player’s life, but also in ours. Suddenly, athletes have to accept that they will never again do the thing that they were best at doing for so long, and we realize we’ll never get to watch them do it again, either. As was the case with Buster Posey, Votto’s retirement hit me harder than I expected it would. There’s a real feeling of mortality when people you were writing about as young players are now old (in baseball terms) and out of baseball.

Okay, that’s enough sentimentality for this stathead; back to Votto’s career and Hall of Fame profile. Let’s look at his career numbers and see how they compare to other first basemen. Classifying players by position is never neat, but for the purposes of this piece, any player who appears on Jay Jaffe’s First Base JAWS leaders list will be considered a first baseman. However, I’ve removed any data from before 1901, simply because professional baseball in the 1800s was as much carnival sideshow as competitive sport. You could argue for a later – or even much later – starting point, but this deep into an article about Joey Votto isn’t the best place to have that fight.

By career WAR alone, Votto’s résumé isn’t that overwhelming, and it doesn’t help his case that he has just over 2,000 hits and fewer than 400 homers at an offense-first position, but one has to take peak performance and career length into consideration. I’m a big believer in looking at peak value — how good they are at their best over an extended period, divorced from the bulk counting stats at the start and end of their careers — so long as we’re talking about a peak that’s beyond just a couple of years. I think Aaron Judge is a Hall of Famer right now, and had I been a voter at the time, I would have cast my vote for Johan Santana. I’m also not positive that Félix Hernández shouldn’t be a Hall of Famer. It isn’t a flaw in the data that Jack Morris has more career WAR than Sandy Koufax, but if you’re using WAR to make the case that Morris was just as good as or better than Koufax, the flaw is how you’re using the tool.

The Hall is about greatness, so I tend to prefer measures that include a peak run — such as WAR7 — and/or focus on wins above average rather than replacement. The table above is sorted by our version of WAR, but for the rest of this piece, I’m going to use Baseball Reference’s WAR, which ranks Votto slightly higher (64.5, 11th) than ours does, because that’s what Jay uses for JAWS. I am also using Baseball Reference’s wins above average to keep things consistent. Excluding anything that happened before 1901, Votto ranks seventh at the position in both WAA (37.7) and WAR7 (46.9) and ninth in JAWS (55.7). Except for those who were busted for performance enhancing drug use, all of the Hall of Fame-eligible players who rank in the top 15 by First Base JAWS have been inducted. Simply, Votto belongs in the Hall of Fame.

Votto’s fairly rapid decline kept him from gaudier WAR numbers. After a big drop-off in his power in 2018, his age 34 season, his resurgent 2021 campaign was a real outlier. But as Orson Welles once said, in one of my favorite quotes – and my desired epitaph – if you want a happy ending, that depends, of course, on where you stop the story. Yes, many of us wanted another chapter, but Joey Votto’s career amounts to a banger of a story.

Michael Kopech didn’t even crack the headline in our coverage of the three-way July 29 trade involving the Dodgers, Cardinals, and White Sox that sent him to Los Angeles, and we were hardly alone. Just about everywhere outside of Chicago and Los Angeles, the focus of the trade landed upon Tommy Edman and Erick Fedde, and rightfully so given the expectations that both would be starters in one sense or another. A fireballing reliever with a 4.74 ERA and -0.2 WAR switching teams may not have been a footnote given Kopech’s history and stuff, but he rated as more of a project than an obvious solution.

Yet even then it wasn’t hard to appreciate that there might be some method to the Dodgers’ madness. After all, in recent years the team has gotten strong results from similarly underwhelming pickups ranging from starters Tyler Anderson, Andrew Heaney, and Alex Wood to relievers Anthony Banda, Ryan Brasier, and Evan Phillips. As Noah Syndergaard’s tenure showed, not all of their salvage jobs were successful. “But more often than not,” wrote the Los Angeles Times’ Mike DiGiovanna in January, “the Dodgers have revitalized the careers of middling pitchers and optimized the production of pitchers they have, their ability to identify and acquire those with untapped potential and implement plans to maximize performance helping to fuel their run of five 100-win seasons in the last seven years.”

While the fact that he has one year of club control remaining probably factored into his acquisition, Kopech has paid immediate dividends. In the three weeks since the trade — a small sample of work all the way around, admittedly — he’s easily been the most productive of the five big leaguers in the three-way deal (the Cardinals’ Tommy Pham and the White Sox’s Miguel Vargas being the others apart from Edman and Fedde). The 28-year-old righty has flat out dominated opponents, allowing just one hit and one walk in 9.1 scoreless innings for the Dodgers, earning the trust of manager Dave Roberts. Last week, with their NL West lead whittled down to two games by the surging Padres and Diamondbacks, Roberts called upon Kopech to close out a pair of one-run games against the Cardinals, and he converted both chances. With the team concerned about overusing a “gassed” Kopech, Phillips and Daniel Hudson have been tapped for the two save situations since (both of them protecting three-run leads). Nonetheless, it’s clear that Roberts has another late-inning weapon, and a much-needed one at that. Read the rest of this entry »

If you’re not a Mariners fan, you maybe haven’t noticed how good of a season Collin Snider is having. While most of the attention — at least pitching-wise — has gone to Seattle’s stellar starting rotation, the 28-year-old right-hander has quietly logged a 1.01 ERA and a 2.07 FIP over 27 relief appearances comprising 26 2/3 innings. Moreover, he has fanned 30 batters while issuing just six free passes and allowing 22 hits, only one of which has left the yard.

Snider was cut loose twice over the offseason, first by the Kansas City Royals, with whom he’d spent parts of two mostly nondescript seasons, and then by the Arizona Diamondbacks, who had claimed him off waivers. The Mariners signed him off the scrap heap in early February, and they’re certainly glad they did. The sample size is admittedly small — again, he’s made just 27 appearances — but the results have nonetheless been noteworthy. To little fanfare, Snider has been superb.

———

David Laurila: You’ve obviously taken a huge step forward this year. Did changing organizations play a role in that?

Collin Snider: “I think changing orgs had a big role in it. I had a meeting in spring training with the pitching staff here, and they showed me the difference in my numbers pitching ahead in the count and pitching behind in the count. There was a substantial difference in good results versus bad results. From that point on it was more of just, ‘Get your stuff over the plate early and often.’ My stuff plays well enough that I didn’t have to really try to do anything else after that.” Read the rest of this entry »

Friends, I come to you today to relieve my soul of a burden I’ve been carrying. I’ve been harboring a cranky, irrational, old man opinion, and worse still, I’ve been lying to you about it.

Time and again, while evaluating pitchers, I’ve praised the slider. Dylan Cease’s slider? Incredible. Andrés Muñoz, Chris Sale, whoever. In the kayfabe my position demands, I must praise a slider that gets outs. But my heart isn’t in it. I am awed by the slider’s effectiveness the same way I’m awed by the voraciousness of a swarm of locusts.

Deep down, I detest the slider. It is a crude instrument, with none of the curveball’s grace or the changeup’s playfulness. The curveball is a calligraphy brush, all swooping lines and fine control. The changeup is a Blackwing pencil, rich and precise, its marks here one moment and gone the next.

The slider is a crayon. Read the rest of this entry »

NEW YORK — On June 2, the Mets’ season was looking grim. At Citi Field, Jake Diekman served up a two-run ninth inning home run to the Diamondbacks’ Ketel Marte, turning a 4-3 lead into a 5-4 deficit. Within a matter of minutes, the Mets fell to 24-35, a season-worst 11 games below .500. After last summer’s deadline sell-off, 2024 wasn’t supposed to be their year, and two months into the season, it seemed clear that was the case. In the two and a half months since, the Mets have reeled off the majors’ fourth-best record (41-26), climbing back into the NL Wild Card race, though an 8-10 record in August has kept them on the outside looking in.

This week has already been full of ups and downs. On Monday night against the Orioles, Francisco Alvarez hit an epic no-look walk-off home run to pull the Mets to within a game and a half of the third NL Wild Card spot. The homer opened what has suddenly become a crucial stretch of the Mets’ season — 10 games in a row against contenders, the last seven of them on the road — with a bang. But the momentum did not carry over to Tuesday, when starter Jose Quintana turned in his fourth sour outing in a row. The 35-year-old lefty served up two big homers while plodding through five innings, while the offense was held to just two hits over six innings by starter Dean Kremer. A late-inning comeback not only fell short but produced a groan-worthy LOLMets moment.

Still, the Mets’ season has featured more good days than bad in recent months, and regardless of what happens going forward, Monday’s win was one for the books. The Mets had squandered a 3-1 lead when starter David Peterson overstayed his welcome in what had otherwise been an excellent outing. With two outs in the seventh, he balked in a run, then served up a game-tying homer to Ramón Urías on his 98th pitch of the night. Meanwhile, from the fifth inning on, 11 out of 14 Mets struck out against starter Trevor Rogers and relievers Colin Selby, Keegan Akin, and Seranthony Domínguez before Alvarez stepped in.  Read the rest of this entry »

Tayler Scott is having a career-best season, and the primary reason is equal parts straightforward and confounding. Thirteen years after being drafted by the Chicago Cubs out of a Scottsdale, Arizona high school, and five years after making his major league debut with the Seattle Mariners, the 32-year-old native of Johannesburg, South Africa is finally featuring his best pitch. Now with the Houston Astros — his 10th big league organization — Scott has put his two-seamer in his back pocket and is throwing a heavy dose of four-seamers.

The numbers speak for themselves. Coming into the current campaign, the right-hander had made 39 big league appearances and logged a 9.00 ERA over 46 innings. This year, Scott has come out of the Astros bullpen 53 times and boasts a 1.86 ERA over 58 innings. Moreover, he has allowed just 32 hits and has a 26% strikeout rate. His seven relief wins are a team high.

Again, the four-seamer — a pitch he’d thrown sparingly in the past — has played a huge role in his success. Per Statcast, he’s throwing the pitch 47.4% of the time to the tune of a .120 BAA and a .265 SLG. Augmenting the offering is a new-ish splitter that has yielded a .122 BAA and a 184 SLG, as well as a slider (.220 BA,.339 SLG) he views as his third option.

Scott shared the story behind his fastball changeover, including why his four-seamer is so effective despite ranking in the 29th percentile for velocity, when the Astros visited Fenway Park earlier this month.

———

David Laurila: You began featuring a four-seamer this year and are having by far the best season of your career. Given that your 92.6 mph velocity is well below the big league average, what makes it so effective?

Tayler Scott: “I learned about vertical approach angle, which is guys with lower slots throwing four-seams up in the zone and creating a flatter angle for the four-seams coming to the plate. They’ve discovered that gets a lot of swings and misses. That’s when I started to throw four-seams. Over the last couple years, it was a pitch that I kind of only used late in counts to strike guys out; I would never really throw it at other times. One reason is that I tended to have a hard time locating it in the strike zone. Read the rest of this entry »

About two weeks ago, Kyle Kishimoto wrote about a shift in the AL West race as the Astros, who had been trailing the Mariners all year, pulled level in the division. Ordinarily, I wouldn’t revisit a topic so soon, especially because Kyle was himself issuing an update to his own previous appraisal of Seattle’s success. But between Kyle’s two posts, the Mariners blew a 10-game division lead to Houston. And in the two weeks since then, well at the risk of steering directly into stereotype, let’s take a look at a graph.

On the morning of August 5, when Kyle’s second piece ran, the Mariners were still actually slight favorites to win the AL West. In the ensuing 15 days, their division title odds dropped by 43.4 percentage points, to just 10.8%. Seattle’s odds of making the playoffs in any fashion are now just 16.4%, which is down 41.6 points. Only three other teams have seen their playoff odds move even 20 points in either direction in that time. One is the Padres. The other two are the Astros and Royals, two of the major beneficiaries of the Mariners’ ongoing slide. Read the rest of this entry »

You can add two more stars to the game’s unfortunate tally of injured players, as Braves third baseman Austin Riley and Diamondbacks second baseman Ketel Marte were both added to the 10-day injured list on Monday. Riley, who has been one of Atlanta’s hottest hitters after an ice-cold start to the 2024 season, was removed from Sunday’s game against the Angels after a 97-mph Jack Kochanowicz sinker went very high and very inside, connecting with his wrist. Marte’s injury appears less serious than Riley’s, but a re-aggravated sprained ankle has put him on the shelf at a key moment in Arizona’s playoff run.

When I ran the numbers on baseball’s most injured teams last week, Atlanta came out second in terms of the most lost potential value, “beaten” by only the Dodgers. Riley, who has gotten MVP votes in each of the last three seasons, has had a bit of a down year, posting a .256/.322/.461 slash line and 2.4 WAR, which represents his weakest performance since before his 2021 breakout. But even if he hasn’t had a particularly sterling season overall, he’s become very important lately, especially as the injuries have piled up and the rest of the team’s offense has swooned. Riley’s seasonal line was as low as .220/.288/.330 back in mid-June; he’d gone more than a month without a homer and had only hit three on the season. Since June 13, however, Riley has led Atlanta’s lineup in WAR and hit 16 round-trippers:

Monday’s MRI, which revealed a broken wrist, puts Riley out of action for 6-8 weeks, meaning that unless the Braves go deep into the playoffs, his 2024 season is probably over. While there’s never a good time to lose a middle-of-the-order hitter, Riley’s loss comes at a particularly awkward point for the Braves, as their seven games against the division-leading Phillies over the next week-and-a-half likely represent their last, best chance to seize the NL East, long-shot though it may be. The Braves seem to have arrested their fall in the standings, winning five of their last seven, but they’re still barely clinging to the last Wild Card spot, as they’re only 1 1/2 games ahead of the Mets and 3 1/2 in front of the Giants.

The silver lining — or arguably a dull gray one — is that Gio Urshela was suddenly available in free agency after being released by the Detroit Tigers on Sunday; the Braves signed him to a major league deal earlier today. The problem, of course, is that the only reason Urshela was available is that he’s having such a poor season that nobody wanted to risk picking up the pro-rated dollars remaining on his one-year, $1.5 million contract. Urshela had a solid little peak, putting up a 118 wRC+ and 8.1 WAR for the Yankees and Twins from 2019 to 2022, but after a fractured pelvis in 2023 and a miserable .243/.286/.333 line this year, he appears to be on the downslope of his career.

While I still think Nacho Alvarez Jr. would have been the best replacement despite his weak debut stint, Atlanta appears to want to play it safer, opting for the veteran Urshela over Luke Williams and maybe a bit of Whit Merrifield if Ozzie Albies returns in September. Without the Riley injury, ZiPS projected a 73% chance of the Braves holding off the Mets and Giants and making the playoffs; replacing Riley with Urshela drops that probability to 68%, while playing mostly Williams at third would cause it to dip a little further to 67%. Despite Urshela only being projected at replacement level or a hair above, paying $400,000 for 1% of a playoff spot is actually a reasonable value. To make room for Urshela on the 40-man roster, A.J. Minter, who is out with hip surgery, was moved to the 60-day IL. However, that doesn’t change the team’s projection, as I had already baked in the assumption that, at best, Minter was very likely to only get a few outings in the season’s final days.

As I mentioned above, Ketel Marte’s injury is far less serious than Riley’s. Marte originally sprained his ankle on August 10 after a Garrett Stubbs slide into second base. The Diamondbacks didn’t place him on the IL, opting to use him carefully in the last week, with a couple late-inning appearances and a game at DH. They’re taking no chances this time, though, and the hope is that he’ll be able to make a quick return after taking some time to recuperate.

As with Riley’s injury, Marte’s comes at a key point in the season for his team. After treading water earlier this season, the Diamondbacks have been one of baseball’s hottest teams, and along with the Padres, they’ve actually made the Dodgers feel at least mildly uncomfortable at the top of the NL West. Before the injury, Marte had been on the hottest run of his career, hitting .333/.422/.652 with 20 homers since the start of June. His 3.9 WAR over that timeframe ranked behind only Francisco Lindor’s 4.2 WAR among NL hitters. Combined with Arizona’s surge, Marte was putting together a reasonable MVP case. Assuming he only requires a minimum stay on the IL, the significant downgrade to Kevin Newman doesn’t represent a serious hit to the Snakes’ playoff hopes; ZiPS has them at 90% odds to make the playoffs, only a 0.5% drop from their projection without the injury. In the best-case scenario, the Diamondbacks would get Marte back just in time for a key four-game series against the Dodgers next week, their last opportunity to directly inflict punishment on their division rival in the standings.

The injuries to Riley and Marte don’t doom their teams to 2024 oblivion, but they do make their respective team’s challenges this year a bit more daunting. But hey, nobody said it would be easy.

I will always have an affinity for hitters with a knack for vertical bat variability. To effectively cover pitches at different heights in the strike zone, a hitter has to vary the angle of their bat relative to the ground to create lift. To hit a pitch at the top of the zone for a line drive, the bat should be flatter, and to lift a pitch at the bottom of the zone for a line drive, the bat should be steeper. It’s a simple concept that some hitters can execute with more consistency than others. Jackson Merrill is one of those guys.

When I first really started getting into the mechanics of hitting, Mike Trout was the dude who made it easy to understand vertical bat variability. Vintage Trout’s lower half looked almost identical across all swings, but depending on the height of the pitch, his entire torso angle would adjust. Through the years, players like Michael Brantley, Freddie Freeman, and Trea Turner have all executed impressive levels of vertical bat variability, too. And unsurprisingly, they all maintained (or still do) strikeout rates well below the league average with great gap-to-gap line drive skills. When Eric Longenhagen first compared Merrill’s swing to that of Brantley, I became very impatient anticipating what the Padres outfielder would do in the big leagues. So far, he’s exceeded expectations.

Through his first 121 career games, Merrill has hit for a 125 wRC+ with a .290/.321/.484 slash line. Over the past month, he’s found his power stroke to go along with his superb line drive swing, and during that span, he’s been one of the best hitters in baseball, with a 182 wRC+ across 104 plate appearances. It’s come at a good time for the Padres, who have picked it up and are only three games behind the NL West-leading Dodgers.

Merrill’s sound mechanics and production at the plate are all the more impressive considering that he is still just a 21-year-old rookie who is also learning a new position. Although his outfield experience in the minors was limited to 45 innings in left field last year at Double-A, he’s already turned into one of the top defensive center fielders in the game (6 OAA).

His ability to go down and get it with the best of them while still covering the top of the strike zone is the key to his success so early in his career. Below is a table highlighting his performances in both the upper and lower thirds of the zone:

Elite hitters have all different shapes of production. Juan Soto mashes everything at the top of the zone, Aaron Judge crushes everything in the heart, and Yordan Alvarez demolishes everything down low. But it’s uncommon for hitters to be this productive on both high and low pitches. In fact, among the 194 hitters who’ve seen 1,250 pitches this season, only two other players have xwOBAs that rank in the top 30 on pitches in both the upper and lower thirds of the zone, Ketel Marte and Marcell Ozuna, who are two of the best 11 hitters in the game by wRC+. Merrill and Ozuna are the only two hitters with top-30 xwOBAs in all three vertical thirds.

As I said before, a hitter needs to employ a flatter swing path at the top of the zone and a steeper one at the bottom. Sounds easy enough, but the tricky part is generating enough bat speed across a range of bat angles to make it work from a damage perspective while maintaining the body control to make contact. What’s notable here is how Merrill does this: Unlike most hitters, Merrill keeps his bat vertically oriented against low and high pitches, which allows him create enough lift to shoot the gaps no matter the height of the pitch. It’s a balance of strength and finesse that Merrill seems to have mastered.

I could throw a bunch of numbers at you to explain this particular skill, but the best way to understand this is by watching what he does with his body and bat. Let’s take a look:

Upper Third

Before watching the lower third swings, here are a few quick notes. He maintains his posture and shoulder plane during all three of these swings. Because of that, he keeps his bat on the same vertical plane as these pitches so he can square up the bottom part of the baseball to create backspin but not get so far under it that he pops them up. Also, his torso backbend on the second swing is fantastic. This move is most noticeable from a hitter like Shohei Ohtani, who right before contact bends his upper body backward to give his barrel space to get behind the ball. Few hitters have the necessary upper body or t-spine flexibility to do this; Merrill is one of them. Okay, now onto some swings in the lower third:

Lower Third

Pay attention to his back shoulder on each of these swings. Merrill’s body and bat are moving together as he swings, and he uses his back shoulder as a guide to get his barrel on plane with pitches in the lower third. Whether it’s a back-foot breaking ball or a dotted heater away, his back shoulder angle lines up his swing.

The important thing to take away from all of this is Merrill has a great understanding of how to use his upper body to get his bat on plane with pitches at different heights. That’s the elite skill carrying his game right now. He has the talent to develop additional tools and sharpen the ones he currently owns as he gains more experience. He’s already started tapping into his power more over the last month or so. He still chases too many pitches and struggles against lefties, albeit in a small sample of plate appearances (70 wRC+, 127 PA), but again, he is 21 and figuring things out in his first big league season. What we’re seeing from him right now is essentially his starting point as a hitter, and that’s really exciting.

Pedro Avila might not strike you as exceptional. He’s mostly on mop-up duty in the Guardians bullpen, hoovering up low-leverage innings. His sinker was deemed the “most normal” in baseball by Leo Morgenstern earlier this year. And his 3.60 ERA and 3.92 FIP is right around average for major league relievers.

But behind this veneer of normalcy lies the weirdest changeup in baseball.

Below is a plot of the average vertical and horizontal moment of every pitcher’s changeup during the 2024 season (minimum 50 changeups, data as of August 15, vertical movement measured without gravity). You have a 50/50 shot of guessing which one is Avila’s:

The brown dot on the left of my beautifully drawn circle is Logan Allen’s changeup, Avila’s erstwhile teammate. Michael Baumann wrote about Allen’s “weird-ass changeup” last July, noting that the pitch had the least horizontal movement of any major league changeup in the 2023 season. (Unfortunately, despite Michael’s request, no “Weird-Ass Changeup World Tour” tag has since been added to the CMS.) The purple dot on the right is Avila’s changeup, which is averaging even less horizontal movement than Allen’s.

But the average movement profile doesn’t fully capture what’s weird about Avila’s changeup. To truly appreciate the weirdness, it is necessary to take a look at why it moves like that.

It starts with his crazy grip. Look at this grip!

He aligns his thumb and pointer finger in a quasi-circle-change grip while pressing on the exact opposite side of the ball with his other three fingers. The funky grip — a circle-change/splitter/forkball/vulcan-change hybrid — informs the way the ball comes out of his hand.

Scott Firth, a former performance coordinator at Tread Athletics, described Avila’s grip in a tweet from January 2023 and the movement profile that results from it.

“Looks like fosh/modified box grip, some guys will cut it hard with 3 fingers on outer part of ball,” Firth wrote. “Low spin low efficiency could catch ssw [seam-shifted wake] either direction depending on cw [clockwise] or ccw gyro.”

The contradictory forces of fade from the pronation and cut from the pressure of his three fingers results in chaos; because of that grip, the ball comes off the pointer finger and middle finger simultaneously, sending the pitch downward:

Avila’s changeup almost imitates a knuckleball in the randomness of its spin axis. A helpful way to understand this is by looking at Avila’s spin-based movement and observed movement. The spin-based movement is the orientation directly after release; the observed movement is the implied axis based on the movement of the pitch. (When the spin-based orientation does not match the observed orientation, it is generally assumed that “seam-shifted wake” is responsible. More on that later.)

The observed spin axis on Avila’s changeup nearly goes around the entire clock. Check out the green bars on the graphic below:

Avila’s changeup might ultimately move similarly to Allen’s from a “shape” perspective, but the aesthetic experience from the hitter’s vantage point is distinct. It’s a complete outlier from the perspective of spin efficiency, defined as the percentage of spin that is either sidespin or backspin/topspin. The median changeup is 95% spin efficient. Allen’s changeup has 72% spin efficiency, one of the lowest marks in baseball. Avila’s changeup checks in at 24% (!!) spin efficiency, which is more like a typical gyro slider than any changeup.

The Guardians broadcast picked up on this following a slow-motion replay of an Avila changeup. After watching the replay, Guardians color commentator Rick Manning remarked that “It’s almost like a forkball but he spins it like a slider.”

Perhaps it goes without saying, but this is not the traditional way to throw a changeup. Driveline, for instance, published an article showing five different grips for aspiring changeup-throwers to try; none of them resemble Avila’s.

The classic changeup is thrown with heavy pronation. Think Logan Webb’s changeup fading down and away from a left-handed hitter:

Some pitchers struggle to throw a changeup with heavy pronation. One key reason, as Noah Woodward pointed out in a March 2023 post, is that the act of “turning over” the ball is awkward for pitchers who don’t throw another pitch that requires turning over their wrist in the manner required of a Webb-esque changeup.

For pitchers like Tarik Skubal or Matthew Boyd with more of an inherent supination bias, the seam-shifted wake changeup is a way to throw an offspeed pitch without contorting their arms in uncomfortable directions.

“I throw a changeup just like a slider now, but using essentially the smooth part of the baseball to create no drag on one side, but seam is on the other side,” Boyd told MLB.com’s Jason Beck in March 2023. “And because of that, I get more movement than I did before, but the pattern of how my wrist is moving is like the other pitches. So it allows for the other pitches to be more consistent.”

Avila’s changeup does not fit neatly in either of these categories. It is, somehow, a pronated seam-shifted wake changeup. That explains why Avila leads the league in the gap between his changeup’s spin-based axis and his observed axis.

But that gap doesn’t tell the whole story. Most other pitchers have a similar pattern when their actual spin orientation deviates significantly from the “spin-based” orientation: It shifts to the left (or right) in a predictable pattern. Take Skubal’s seam-shifted wake changeup, for example. The “observed spin” is shifted to the left of the spin-based movement.

Avila’s changeup is not like that. Because of the heavy gyro spin that his grip produces, the pitch leaves the hand at somewhat random orientations and can either fade or cut, as the movement map of all his changeups in 2024 shows. Notice how the green dots (his changeups) can end up on either side of the pitch plot:

So Avila’s changeup is definitely weird, but is it good? It certainly produces some bizarre swings, even when it’s poorly located. Heliot Ramos, for one, looked flummoxed after whiffing on one middle-middle Avila changeup:

Avila’s changeup gets a lot of whiffs — among changeups thrown at least 100 times, his ranks in the 85th percentile in swinging strike percentage and the 78th percentile in whiffs per swing. On the other hand, he throws one out of every six changeups in the “waste” zone, which sort of makes sense to me — that grip feels prone to misfires. (Shout out to Alex Chamberlain’s pitch leaderboard for these stats.)

While Avila’s changeup has graded out as basically average from a run value perspective, I’m not always sure that run value is the best way to evaluate the quality of a given pitch. There are interaction effects between pitches — in other words, the thought of the changeup in the batter’s mind might improve the quality of his fastball — and Avila is using the changeup as his primary out-pitch and getting pretty good results.

Given that the Padres DFA’d Avila in April, this season looks like a success for him, and the changeup is without question a big part of all that. As always with pitching, weird is where you want to be.
