A couple of weeks ago, I saw Jonah Heim take a called strike that he felt should have been a ball. As a catcher, Heim knew better than to argue. Instead, he performed the delicate dance of the catcher who wants to make a point without showing up the umpire. I’m not sure if the clip below is the exact pitch I saw, but it’s certainly representative of the conundrum a catcher faces when he doesn’t like the strike zone.
You can see Heim duck his head and furtively say something to home plate umpire Doug Eddings. I like to imagine that whatever he says begins with, “I beg your pardon, good sir.” He doesn’t make a show of his displeasure. He asks something, Eddings nods his head yes, and everyone moves on with their lives. Still, Heim thinks he’s seen ball two, and it’s hard to blame him. Even the person operating the score bug got fooled.
For some reason, that little moment has been rattling around in my head. I tend to think too much about the relationship between umpires and catchers. It doesn’t seem possible that they could spend every night doing what they do in the proximity that they do it in without developing a bond. Read the rest of this entry »
Bobby Miller was pitching in High-A when I first interviewed him for FanGraphs in June 2021. Drafted 29th overall the previous summer by the Los Angeles Dodgers out of the University of Louisville, the right-hander possessed both a high-octane heater and a lofty ceiling. Since making his MLB debut this past May, he’s met those expectations, going 9–3 with a 3.80 ERA and a 3.67 FIP over 17 starts. The 24-year-old is also coming off of his most impressive outing. Facing the powerhouse Atlanta Braves on September 3, he allowed just three hits and one run in a career-high seven innings.
Miller discussed his continuing evolution as a pitcher and his efforts to find consistency with his slider when the Dodgers visited Fenway Park in late August.
———
David Laurila: We talked two years ago when you were pitching for the Great Lakes Loons. What has changed and what has stayed the same since that time?
Bobby Miller: “A lot of stuff is the same. At the end of the day, it’s still the same game. But the competition is obviously a lot higher. The hitters are lot more disciplined and experienced. Most of them have seen the game’s best arms, so when you’re out there, you’ve got to know that they’ve faced guys just as good or better than you are.
“Game-planning comes in a lot more at this level. I feel like game-planning is super important to learn in the minor leagues, studying hitters and all that, and I wish I’d have learned more before I came up here. While I had somewhat of an idea, I still have a lot of room to improve on that. I think that’s the biggest thing for me: how much time I spend looking at the upcoming lineups I’m going to face.”
Laurila: Basically, what hitters’ hot and cold zones are, and what they hit and don’t hit in certain counts.
Miller: “Yeah. What to avoid in certain counts. When they’re aggressive and when they’re not aggressive. How aggressive they are with runners in scoring position. At some point, I could get better at learning the baserunners, too. But at the end of the day, the most important thing is getting the batter out of the box. It’s about getting outs for your team.” Read the rest of this entry »
When the Phillies signed Trea Turner to an 11-year, $300 million contract over the winter, the second-largest contract in franchise history, they were probably prepared for Year 11 to be a bit underwhelming, not so much Year One. Turner got off to an excellent start in Philadelphia, beginning the season with 12 hits in the first seven games with two triples. Once his seven-game hitting streak was snapped, the next four months turned into an unbelievable slog: .225/.282/.354 with 10 homers. On the morning of August 5, his OPS hit a season-low .656. But over the last month, Turner has been one of the hottest hitters in baseball.
During the hottest months of the summer, one of the most common questions I got was some variant of “is Trea Turner broken?” My usual answer was that he’d probably be fine, even if expectations had to be lowered a bit, but it felt a little less convincing. The zStats I ran for hitters in early August as part of the “full-fat” ZiPS saw Turner as having a better season than was reflected in his overall numbers, with a .728 zOPS compared to that .656 mark. That wasn’t enough to make the leaderboard, headed by Spencer Torkelson (with a .975 OPS since then), but it was still a significant gap. And I doubt the Phillies or the fans would have felt much relief even with the .264/.309/.419 line that zStats gave him.
Back then, I re-ran Turner’s long-term projections to see what kind of bounceback ZiPS was expecting. While the computer saw a pretty good recovery in 2024, it was well off his preseason numbers. There was also a lot more risk in the mix, significantly pushing his numbers in future years down. Read the rest of this entry »
We haven’t seen much of Royce Lewis at the major league level yet, thanks in large part to a twice-torn anterior cruciate ligament. But what we have seen of the first pick of the 2017 draft has been impressive and, lately, otherworldly. On Monday against the Guardians, the Twins’ third baseman clubbed his third grand slam in an eight-game span, part of a longer hot streak that includes seven homers in his past 14 games.
Lewis’ latest slam came at the expense of Lucas Giolito, who was making his debut for the Guardians after being claimed off waivers from the Angels on September 1. Already down 2–0 in the second inning, Giolito was one strike away from a 1-2-3 inning when he lost the plot, issuing three walks, throwing a wild pitch, and allowing a single. That left the bases loaded for Lewis, who had already singled in the first inning. Giolito fell behind 2–0, then left Lewis a 92-mph belt-high fastball on the inner third of the plate. He hit a towering shot to left field; its 107.6-mph exit velocity was garden variety, but that 41-degree launch angle was majestic:
The slam broke the game open. Lewis would later add a two-run single off David Fry — the Guardians’ utilityman threw four innings of thankless relief — in what turned out to be a 20–6 romp. Those six RBIs gave Lewis 10 in a two-game span, as he went 3-for-5 with a three-run homer (off Jon Gray) and four runs driven in in the Twins’ 6–5 loss to the Rangers on Sunday. Only one player, the Orioles’ Ryan Mountcastle, has collected more RBIs in a two-game span this season (11 on April 10–11).
Lewis’ previous grand slams came at the expense of the Rangers’ Chris Stratton on August 27 and the Guardians’ Xzavion Curry on August 28:
The trio of salamis ties Lewis for this year’s lead alongside the Dodgers’ Max Muncy, the Astros’ Alex Bregman, and the Rangers’ Adolis García. Via the Elias Bureau and MLB.com’s Sarah Langs, he’s the first rookie with three grand slams in a span of eight games or fewer, and just the fourth player to bunch three such hits so closely, joining the Yankees’ Lou Gehrig (five games in 1931), the Tigers’ Jim Northrup (four games in 1968), and the Rangers’ Larry Parrish (eight games in 1982).
Including homers on August 23 (off the Brewers’ Corbin Burnes), August 24 (also off Stratton), and August 29 (off the Guardians’ Hunter Gaddis), Lewis is hitting .321/.400/.736 with seven homers and 22 RBI in 60 plate appearances over his last 14 games, all against the Brewers, Guardians, and Rangers. It’s a remarkable surge even from a player who has wielded a potent bat when available… but has unfortunately been rather scarce in recent years.
Recall that after reaching Double-A in 2019 and spending the following season at the Twins’ alternate training site, Lewis first tore his right ACL in February ’21 and missed the entire season. He was ready to go for the start of 2022 and bounced up and down between Triple-A St. Paul and the majors for the season’s first two months, making his major league debut on May 6 but playing just 11 games before returning to Triple-A. After another 10 games down on the farm, he returned to the majors on May 29, but three innings into what was his first major league appearance in center field, he re-tore his ACL — partially this time, not fully as in the first time — making a leaping catch at the wall and missed the rest of the season. For his time with the Twins, he hit a tantalizing .300/.317/.550 in 41 PA.
Lewis made his 2023 debut with Double-A Wichita on May 11 and, after two games, returned to St. Paul. After homering four times in eight games, he was back in Minnesota. Exactly one year after his last ACL tear, and one week before his 24th birthday, he homered off the Astros’ J.P. France in his second plate appearance, then added a game-tying single in the ninth. He played regularly at third base throughout June but strained an oblique on July 1, which sidelined him until August 15. He was hitting well before the injury, and he’s hit even better since coming back:

As you can see from those improved strikeout and walk rates, Lewis has taken a more disciplined approach since returning. He’s lowered his chase rate from 38.6% to 32.2% and his swing rate from 50.8% to 46.2%; meanwhile, his swinging-strike rate has dropped from 13.3% to 9.7%. He’s done a much better job upon reaching two strikes than before, improving from .220/.264/.280 (51 wRC+) with a 52.8% strikeout rate to .231/.333/.333 (91 wRC+) with a 33.3% strikeout rate. In late June, he spoke of adjusting his two-strike approach to a more aggressive, contact-oriented one. ViaThe Athletic’s Dan Hayes:
“It’s who I am,” Lewis said. “It’s just me being able to put the bat on the ball and make contact and make people do things. You’ve just got to play the game and when you strike out, no one is doing anything except for the pitcher. Honestly, I get frustrated after a while and I just go back to being like — what I said to (hitting coach David Popkins) is, ‘I’m going to turn into (Luis) Arraez today, just touch the ball. There’s a lot of grass out there.’”
…“It’s a mindset,” Lewis said. “Not waiting for a pitch you can drive because these guys are going to execute. If they dot one up on the outer third, that’s 0-1. Then they do it again, 0-2. ‘OK, great, now you’re 0-2.’ Now you’re battling and you’re looking for a pitch to drive at the same time, that doesn’t work. I looked at where some of our plans were going and how the pitchers were pitching us and they weren’t attacking us with our plan of getting a mistake. I was like, ‘Why don’t I just start being aggressive, putting the ball in play? I know I can at least touch it and go to right field.’”
Since returning, Lewis is hitting the ball in the air far more often, and harder in general:

Note that Lewis is also pulling the ball more frequently and, as that last column illustrates, has more than doubled the frequency with which he hits fly balls in the air. Five of his 11 homers have come via pulled flies, one before the injury and four since returning.
For all of that, it’s worth noting that Lewis is riding a .368 BABIP, which is higher than any batting title qualifier save for Freddie Freeman (.375). That said, 15 other players with between 150–425 PA (around enough to qualify) have higher marks, including three of Lewis’ teammates and another former number one pick whom I checked in on about six weeks ago:
All statistics through September 4. Minimum 150 PA. * = qualified for batting title
When I wrote about Moniak, who’s in the midst of a breakout year with the Angels (despite a 2.8% walk rate and 34.8% strikeout rate), he had a .427 BABIP through 165 PA. Since then, through his next 151 PA, he’s produced a .365 BABIP — still incredibly high, just a bit behind Lewis, yet 72 points lower than that first stretch. That said, Julien, Solano, and Jeffers all have higher BABIPs than Lewis in at least 96 more PA, with Solano having more than twice as many PA.
It’s rare but not unheard of for so many teammates to sustain such numbers. Four other expansion-era teams have had four players with at least a .360 BABIP in 150 PA; in fact, the Twins entry in that group sustained those BABIPs through at least 350 PA for all four:

Lewis has the highest wOBA-xwOBA differential by a seven-point margin, the third-largest differential in batting average, and the fourth-largest in slugging percentage. Note that the top six players in that table are all short of qualifying for the batting title; those gaps tend to shrink as the sample sizes increase.
While it’s tempting to chalk up some of the differentials to Lewis’ 76th-percentile speed, his eight hits on grounders and line drives that have stayed in the infield don’t move the needle that much, and none of his five doubles are the result of hustling to stretch singles. On the contrary, a 398-footer that he hit off the Rangers’ Andrew Heaney at Target Field on August 24 would have been a home run in 24 of the other 29 ballparks.
Even if his production is a bit beyond the bounds of sustainability, Lewis’ return has helped to shore up the Twins’ third base situation. The team made the Replacement Level Killers list ahead of the trade deadline, with Jose Miranda, Kyle Farmer, Willi Castro, and Solano combining with Lewis’ first stint to hit a meek .247/.317/.353 for a 90 wRC+ and 0.5 WAR. With Lewis making 14 of the team’s last 18 starts at third (plus four more at DH) and Jorge Polanco, Castro, and Farmer seeing time in the period between that article’s publication and Lewis’ return, the group is up to .260/.333/.388 (101 wRC+) with 1.8 WAR. The Twins have widened their AL Central lead from three games to seven since that list ran and from 4.5 games to seven since Lewis’ return. He’s just been part of the parade, as the Twins as a team have hit .275/.362/.489 since August 15, good for a 134 wRC+ (fourth in the majors) and 6.42 runs per game (third).
On a team whose biggest stars, namely Carlos Correa and Byron Buxton, have disappointed, Lewis has helped pick up the slack, and if what he’s done isn’t as sustainable as it is flashy, his in-season evolution is certainly encouraging. After three mostly lost seasons, the Twins can’t ask for much more than that.
Last season’s rookie class introduced us to some instant stars. Julio Rodríguez and Adley Rutschman became the first pair of rookies to reach 5.0 WAR in the same season since Albert Pujols and Ichiro Suzuki in 2001. Teammates Michael Harris II and Spencer Strider were just shy of 5.0 WAR themselves, with the latter’s 4.9 the highest total by a rookie pitcher since Hideo Nomo in 1995. Rodriguez, Rutschman, and Harris were all top-25 position players in baseball by WAR, with Steven Kwan not far behind at 30th, and Strider finished eighth among pitchers despite spending the first two months of the season in the bullpen.
This year, an arguably more impressive barrage of talented youngsters has arrived in clubhouses across the league. Corbin Carroll currently ranks eighth in WAR thanks to a .376 wOBA and the most baserunning value in the league at 11.0 runs above average; he’s running away with the NL Rookie of the Year Award. James Outman is helping the Dodgers out with a productive (if streaky) bat and centerfield defense worthy of his name. Gunnar Henderson shook off a slow start at the plate with a productive summer, clearing 3.0 WAR before the calendar turned to September and positioning himself as an award candidate in the AL. Matt McLain (who is battling an oblique injury at the moment) and the Giants’ Patrick Bailey didn’t even arrive until mid-May, but both have reached the 3.0 WAR mark in under 100 games.

In August, the Phillies hit 59 home runs, which is the highest total for a month in franchise history and tied for the third-highest total in any single month by any team in history. It was a remarkable performance, but perhaps not a particularly surprising one given how this roster was constructed; by design, Rob Thomson’s charges are large, strong, and (of late) increasingly shirtless. They were born to mash.
Last week, I had the good fortune to be present at Citizens Bank Park as five of those 59 home runs took flight in a single evening, off the bats of five different Phillies. This was one of those close, muggy summer nights that define the mid-Atlantic summer; with a pleasant, gentle breeze blowing out to left field, the ball was roaring out of the park. It wasn’t just the Phillies; the Angels dingered three times themselves. Two of those came off the bat of Luis Rengifo, hardly a man whose public stomps and chants are included in the Home Run Derby every year.
But as the Phillies laid 12 runs on their opponents, the play that stuck in my mind was the opposite of a home run. In the sixth inning, the Phillies batted around and scored six runs to turn a 4–2 deficit into an 8–4 lead; one of those came on a squeeze bunt by Johan Rojas. It was a lovely push bunt by a speedy right-handed hitter, the baseball equivalent of spreading room temperature compound butter on a slice of crusty bread. “Man, we should see that more often,” I thought to myself.

Bobby Witt Jr. is more than just the best player on a bad team; he’s potentially on his way to becoming a superstar. Playing in his second big league season, the Kansas City Royals shortstop has 28 home runs and 39 stolen bases to go with 5.0 WAR. Projected by Eric Longenhagen as “the face of this franchise’s resurgence” during last year’s rookie campaign, he debuted at age 21 and didn’t turn 23 until this past June. And he’s been one of baseball’s best hitters in the second half, posting a .399 wOBA and 152 wRC+ since the All-Star break.
Selected second overall in the 2019 draft behind Adley Rutschman, the Colleyville, Texas native approaches his craft with a keep-it-simple attitude, at the same time continuing to hone a swing that’s always come natural to him. It’s hard to argue with success.
Witt discussed his evolution as a hitter when the Royals visited Fenway Park in August.
———
David Laurila: I’ve asked a number of guys whether hitting is more of an art or more of a science. How do you view it?
Bobby Witt Jr: “I think it’s more of an art, because of the swing. So many people have different types of swings. I feel like you form your swing at a young age, and you pretty much critique it off of that. That’s how I look at it.”
Laurila: There is obviously a lot of data in today’s game. I’m sure you’ve studied your swing.
Witt Jr: “Yes, but I’m not really big into the data. I’m more of a visual learner. I see things that I like to do, whether it’s watching guys on TV, or… like, growing up, I would try to emulate guys’ swings. That was kind of how I made my swing.”
Laurila: Whose swing did you try to emulate?
Witt Jr: “Pretty much whoever I was really liking at the time. I grew up a big Red Sox fan and was always kind of smaller growing up, so Dustin Pedroia was one. I had the narrow stance with the big leg kick. I also liked watching Prince Fielder a little bit and transitioned into a toe tap. So just watching guys and seeing what they’re doing on the field, seeing what their approach was. From a young age, I was trying to emulate that to myself.” Read the rest of this entry »
This year, trade deadline season kicked off when the Rangers acquired Aroldis Chapman from the Royals at the end of June. Texas desperately needed relief help, so it pulled an early trigger in getting Chapman a full month ahead of the deadline. In today’s game, teams moving rental relievers typically do not get anything too exciting in return. That seemed to be the case with Kansas City’s part of the deal: Cole Ragans and 17-year-old outfielder Roni Cabrera. Emphasis on seemed.
Ragans had pitched 24.1 innings in relief across 17 games with the Rangers after an extended but rough debut in 2022. Like last year, things hadn’t gone well. He walked 13.2% of the batters he faced, and hitters slugged .561 against his four-seamer. In that short span, he accumulated -5.2 run value on that pitch alone. Even with a nasty changeup and a four-tick velocity jump from ’22, he was still struggling to get the results he needed.
But after his move to Kansas City and a rough first outing, everything changed. Eno Sarris’ profile of Ragans from last week does a fantastic and thorough job at explaining his career turnaround, from his training at Tread Athletics in the offseason to create his velocity jump to consulting with them and Royals pitching coach Brian Sweeney after his first start in Triple-A Omaha to add his gyro slider. I strongly urge you read the piece, because mine is as a supporting actor to that story. Read the rest of this entry »
Steve Sparks had a solid playing career. The now Houston Astros broadcaster debuted with the Milwaukee Brewers two months before his 30th birthday, in 1995, and went on to toss butterflies in the big leagues through 2004. His best season came with the Detroit Tigers in 2001 when he logged 14 wins and posted a 3.65 ERA over 232 innings.
Sandwiched between the knuckleballer’s stints in Beer City and Motown were a pair of seasons in Anaheim, where his teammates included Orlando Palmeiro. According to Sparks, the left-handed-hitting outfielder wasn’t always a left-handed-hitting outfielder.
“He was originally a right-handed second baseman, but he broke his arm,” the pitcher-turned-broadcaster explained prior to a recent game at Fenway Park. “He was ambidextrous to begin with, so he started playing the outfield throwing left-handed, and that’s how he remained. I played with Orlando, but he never told me that. Joe Maddon was a minor league field coordinator with the Angels, and he’s the one who told me.”
Sparks proceeded to point out that Palmeiro made the final out of the 2005 World Series against the Chicago White Sox while playing for the Astros.
Meanwhile, an outfielder whose best big-league seasons came with the Boston Red Sox played with Sparks on the rookie-level Helena Brewers in 1987. Read the rest of this entry »
Late on Tuesday night, baseball fans all over the world tuned their dials to the ninth inning of the Giants and Reds’ matchup in San Francisco. Through eight innings and 25 batters, Giants starter Alex Cobb had allowed just a single baserunner on a Casey Schmitt error, while setting down the other 24 in order. In the ninth, Cobb sandwiched a walk between two routine fly outs before leaving a splitter over the heart of the plate to Spencer Steer, who crushed an opposite-field liner past the outstretched glove of right fielder Luis Matos to end the no-hitter and the shutout. While a splitter ended Cobb’s no-hit bid tantalizingly close to completion, it’s also the reason his attempt got that far in the first place. Even independent of Cobb’s brilliant outing, his splitter made history in its own way on Tuesday night.
Before going into the splitter, let’s talk about Cobb’s general approach to pitching. He’ll try to catch you off guard with a knuckle curveball on the first pitch, hoping to steal strike one (nine of the 11 curveballs in his complete game were on first pitches), but after that he almost exclusively throws sinkers and splitters in near-equal proportion. These two pitches operate similarly – both leverage the power of seam-shifted wake to maximize arm-side movement, missing barrels and getting batters to hammer the ball into the ground when they make contact. But a quick look at the plate discipline metrics shows his distinct goals in utilizing each pitch:

Like many pitchers who throw splitters, Cobb uses his as a weapon to get hitters to chase below the zone. He’ll get hitters into uncomfortable counts by filling the zone with sinkers, then throw a split that looks nearly identical before diving beneath their barrels. Splitters are pretty uncommon in the majors – while 2023 has represented a peak in splitter usage, they still only represent about 2% of total pitches. While there are others who throw splitters, including Kevin Gausman, Taijuan Walker, and most notably former NPB players like Shohei Ohtani, Kodai Senga, and Shintaro Fujinami, what separates Cobb from the rest of the pack is the sheer frequency with which he throws them. In the past three seasons, he’s ranked first, first, and second in splitter usage rate among starting pitchers, throwing them 38% of the time this year. This splitter, dubbed “The Thing,” ranks second among splitters to Gausman’s in pitch value since Cobb’s debut in 2011. The Thing isn’t just Cobb’s main secondary pitch, it becomes his only secondary pitch in deep counts. And sometimes, he’ll make it his primary pitch.
Cobb threw 83 splitters on Tuesday. Since the pitch tracking era began in 2008, no one else had ever thrown 80 splitters in a single game. Or 70, for that matter. Heck, besides a lone Brad Penny start in 2010 with 66 splitters, no one else had even thrown 60. Cobb’s shattering of the single-game splitter record wasn’t just a result of his pitch count (his 131 pitches thrown is the highest since Mike Fiers‘ no-hitter in 2019); he ranks behind only Penny in single-game splitter percentage, as they comprised 63.4% of his total offerings. Even throwing 50% splitters in a game is a rare occurrence, though it’s unsurprising to see Cobb dominating that leaderboard as well. In fact, all nine of his majority-splitter games have come in the past two seasons:
Cobb’s splitter-first approach in this game offered many advantages over his typical plan of attack, which involves using sinkers to set up the splitter. The first – and most obvious – can be seen from a quick glance at his splits (no pun intended). His splitter is a darned effective pitch, leading his arsenal in chases, swinging strikes, ground balls, wOBA against, and overall run value. If you have a pitch that can do almost everything well, why not throw more of them?
Second, this change in pitch usage was likely a result of advance scouting on the Giants’ part. While the Reds’ offense is middle of the pack versus sinkers, they rank 13th in the NL in wOBA against offspeed pitches. One hitter who particularly struggles against offspeed stuff is TJ Friedl, hitting just .167 with a 34% whiff rate. Cobb capitalized on this weakness by throwing him 11 splitters compared to just four sinkers, three of which came on his first pitches of the game. Friedl’s 0-fer brought his line against splitters to a measly 1-for-19. Reds hitters swung and missed 18 times in their effort to muster up one hit, a season high for Cobb. Unsurprisingly, all 18 whiffs came against The Thing.
Finally, scaling back the sinker in favor of the split has made the sinker even more effective, especially in taking free strikes when hitters were expecting a splitter to dive beneath the strike zone. While Cobb’s surface-level results have been shockingly consistent in the past three years, posting ERAs in the mid-threes, he’s experienced extreme levels of variance under the hood. After posting an impressive 2.80 FIP and 3.15 xERA in his debut season with the Giants, his FIP has climbed by a full run and his xERA has jumped to a scary 4.64. While he’s earning fewer whiffs than before, the most noticeable difference from last year is a near doubling of his home run rate. While it’s easy to point to an outlier HR/FB rate and claim bad luck, his barrel rate has spiked at a rate proportional to the increase in dingers.
The sinker has regressed the most, allowing nine homers so far (compared to just four last year) and a .365 xwOBA, the highest of any of his pitches. On average, he’s thrown his sinkers higher than any other season in his career, preventing it from working its magic as a groundball pitch. And while a difference of a couple inches may not seem significant, just a few mistake pitches can have an outsized effect on barrel and home run rates. Indeed, his sinker’s Location+ has fallen from 105 to 102 over the past two seasons, as higher sinkers tend to be hit harder and on a line. In this start, he missed spots with both pitches along his arm’s path through the zone, but his ability to draw chases on low splitters kept him out of dangerous hitters’ counts:
If hitters are doing more damage to the sinker than they used to, then it’s in Cobb’s interest to get as few swings as possible against it. This is where the splitter comes in. Batters thinking of the splitter as the primary pitch may give up on offerings that they expect to move out of the zone, instead watching them flutter over the plate, even when located suboptimally. In the seventh inning, both Steer and Elly De La Cruz took first-pitch sinkers in the nitro zone, setting the table for a barrage of splitters chased outside the zone that led to a strikeout and groundout. Of Cobb’s 36 sinkers thrown, 17 were taken for strikes, giving him the upper hand in countless plate appearances. While the average hitter swings at about two-thirds of the pitches they see in the zone, Reds hitters saw 23 in-zone sinkers and swung at just six of them. Even when they did swing, none of the balls put in play against it had an xBA higher than .200. In total, Cobb racked up 28 called strikes on the night, tied for the second most of any pitching performance all year.
Leading with the splitter allowed Cobb to maximize the strengths of his wipeout pitch, while simultaneously shielding the weaknesses of his sinker. The synergy of his arsenal, along with added velocity, has brought Cobb to a new career apex at an age when many pitchers are in decline. And he’s doing this despite recovering from two major injuries and temporarily losing feel for his signature pitch. Yet, his 3.20 FIP over the past three seasons is the best stretch of his career, and he’s recently added his first All-Star appearance to the mix. Losing a no-hitter just two strikes away from glory can be heartbreaking, but he’s only come back stronger from adversity before. That’s just The Thing about Alex Cobb.
