Bryce Miller has improved on his 2023 rookie season with the Seattle Mariners. Especially notable are his ERA (3.46 versus last year’s 4.32), FIP (3.70 versus 3.98), and OPS against opposite-handed hitters (.685 OPS versus .917). At the same time, many of his numbers have been strikingly similar. When I spoke to the 25-year-old right-hander at the end of July — he’s since made two starts — his win-loss record and average fastball velocity were identical to last year’s marks, as were his FB% and HR/FB%. His strikeout rate differed by just a few percentage points.

I cited those similarities to the righty, then proceeded to ask him what differentiates this season’s version of Bryce Miller from last year’s.

———

Bryce Miller: “I think that type of stuff is very similar, but the lefty-righty splits are quite a bit different. Last year, lefties batted over .300 against me. This year, it’s around .215. I think the addition of the splitter has been big, and I’ve also been locating better. If you look at the heat maps from last year, a lot of the fastballs were in the middle of the plate. This year, I’ve gotten them [elevated] a little better for the most part. So getting the heaters up and the splitters down has helped me out a lot with the lefties. That’s really been the main thing.”

The other day, I wrote about Jake McCarthy’s BABIP, and touched on an assumption about which kinds of hitters are going to put up outlier numbers in that stat. McCarthy hits a lot of grounders, which generally produce a higher BABIP than fly balls (though they’re less productive by other metrics). He’s also left-handed and very fast, which means he ought to be able to beat out grounders for infield singles.

So let’s take a little gander at the infield hit rate leaderboard for qualified hitters. This is the percentage of groundballs a batter produces that turn into infield hits. Simple enough:

So yeah, Bellinger is primarily known for grinding hanging curveballs to make his bread, but in spite of his size, he is a left-handed fast guy. That tracks. Peña is a righty, but he’s very fast. His average home-to-first time is actually in the top 20 among all hitters — lefties and righties alike — this season. And because Peña hits so many grounders, he leads all batters in total infield hits with 24.

And then there’s Rhys Hoskins. Wait, what? Read the rest of this entry »

Despite notching two wins over their last six games, the White Sox are flirting with history, and not the good kind. As of this morning, Chicago stands 63 games below .500, 42.5 games back in the AL Central, and on pace to finish 39-123. Out of compassion, I will refrain from reciting the record of the 1962 Mets, but the players from that team who are still with us are likely taking this time to get the champagne good and chilled. Hard as it may be to believe, the goal of this article is not to dunk on the White Sox. Instead, as we enter the home stretch of the season, I’d like to consider how they’ve affected the playoff picture.

The White Sox have played 25 of the other 29 teams in the league, and they have distributed to those fortunate franchises a net total of 63 victories in the same way that an elderly man on a park bench distributes bread to the legion of ravenous pigeons jockeying for position at his feet: indiscriminately. For a few weeks now, I’ve been wondering whether the landscape would look different if those 25 teams never had the good fortune of playing the White Sox. Whom have the White Sox helped or hurt the most? Read the rest of this entry »

Last week, I cracked the PitchingBot black box open a tiny bit and asked it to show me the worst pitches of the year. It was for fun, mostly; I think there are some interesting data in there, but the main thing I learned was that the worst pitches are non-competitive balls. That’s always a tough concept to grasp, because the ones that stick with us are the hanging sliders and no-ride fastballs right down the pipe, the kind of pitch that we see and go, “Oh I could hit a home run on that.” Like this one:

That’s the worst pitch in baseball this year by one specific metric: the likelihood that PitchingBot assigns it of turning into a home run. I’ll show you some more of them in a moment, but first I thought I’d lay out how I did this so you can get a sense of how the model is reaching its conclusions.

Cameron Grove, the creator of PitchingBot, wrote about this idea back before he started working for the Guardians, and he was kind enough to nudge me in the right direction when it came to looking at pitches not just for the “worst,” but the ones that are the most crushable.

This is Michael Rosen’s first piece as a FanGraphs contributor. You may have read his previous work at the site, including his article about the Kirby Index, a metric he created to measure command using release angles. He lives in Los Angeles and works as a transportation planner.

Earlier this year, I tried to solve the riddle of how Shota Imanaga threw his invisible fastball. The pitch had (and still has) a rare combination of traits: At the time of writing, only Imanaga and Cristian Javier threw fastballs from super flat vertical approach angles (VAA) with elite induced vertical break (IVB). A fastball with a flat VAA or high IVB plays a trick on the hitter’s perception; a fastball with both qualities becomes nearly unhittable, or invisible, when located at the top of the zone. I posed two questions in that piece: Why was this invisible fastball so rare? And what was Imanaga specifically doing to throw a fastball with these traits?

The first question can be answered, my research shows, by looking directly at release angles. Release angles reflect the direction that the pitcher is aiming the ball at release, which I wrote about at length in my article on the Kirby Index from May. That act of aiming — specifically, the direction the ball is oriented out of the pitcher’s hand — also affects the amount of backspin on a four-seam fastball. Read the rest of this entry »

I have a secret to tell, one that might surprise you. I think that baseball analysis is too complex. I can’t keep track of it all. There are too many numbers, too many ways to approach things, too many parts of the game that might be good in one context, bad in another, and neutral in a third. My whole job is to analyze baseball, and yet I find myself drowning in data more often than controlling it. My solution is to simplify. I look for players’ superpowers – carrying tools, in baseball parlance. Aaron Judge is power personified, with the rest of his game building off of that. José Ramírez is a bat control genius. Mookie Betts is the most coordinated man alive. Luis Arraez could hit soft line drives the other way in his sleep. These shortcuts help me think about how the rest of a player’s game fits in. But I have a problem: I’m trying to analyze Jackson Chourio, and I can’t figure out what his superpower is.

You might think it’s his speed. You wouldn’t be wrong, exactly. He’s one of the fastest players in baseball, and he uses that to his advantage all over the place. He’s an excellent baserunner and defender. He eats up ground in the outfield in huge loping strides, the kind of quick you only notice after the fact. I watch him and think he’s an above-average center fielder. The Brewers have only played him in the corners this year, since they’re overrun with excellent defensive outfielders and Chourio has the least experience, but he’s so good that if he ends up in a corner, he might be peak Jason Heyward there.

I guess we could stop the article there, but speed isn’t really a superpower for many great players. Sure, Bobby Witt Jr. and Elly De La Cruz are the current kings of sprint speed, but you don’t look at their games and say, “Oh, the main thing about them is that they’re fast.” That’s the territory of Billy Hamilton or Victor Scott II, and those guys just aren’t stars in the way that I think Chourio will be. I’m looking for an offensive weapon that makes everything work for him, one that explains how he’s hitting major league pitching at age 20. Read the rest of this entry »

Thomas White is having an impressive first full professional season. Drafted 35th overall last year by the Miami Marlins out of Phillips Academy in Andover, Massachusetts, the 19-year-old left-hander has a 2.84 ERA, a 2.99 FIP, and a 29.6% strikeout rate over 76 innings between Low-A Jupiter and High-A Beloit. His late-May promotion to the higher of those two levels came for a simple reason. As our lead prospect analyst Eric Longenhagen explained when assigning him a 45+ in early June, White’s stuff was simply too good for the Florida State League.

I had an opportunity to talk to the promising youngster when Beloit played at West Michigan earlier this week, and one of the things I made it a point to learn about was the mindset that augments his arsenal. I began by asking him how much of a role analytics are playing in his development.

“I’m starting to learn more about the actual numbers and how all that stuff works,” White told me. “At the end of the day, I like to just go out and get outs — I’ve never been a big tech guy — but I definitely know a lot more about my pitches now that I have access to all the data. So, I’m still learning, and I want to learn, but the best measurement for me is how hitters react to them.”

The pitches that hitters are reacting to include a four-seam fastball that has been averaging, according to White, 95.6 mph and 17.5 inches of vertical ride. He is also throwing a two-seam changeup and a sweeper-slider. Currently in the works, but not yet part of his repertoire, is “a shorter gyro pitch,” either a cutter or a hard slider.

The Orioles have had their ups and downs lately. Since July 7, a point at which they led the American League East by three games, they’ve gone 11-15, briefly dropping out of the top spot; as of this writing, they’re currently tied with the Yankees at 68-48. They were among the busiest teams ahead of the trade deadline, but their approach was geared more towards quantity instead of quality, as none of their additions rate as an impact player. They’ve dealt with a handful of injuries lately, but in the absence of infielders Jorge Mateo and Jordan Westburg, top prospect Jackson Holliday has gotten another look, and so far he’s been quite impressive.

Recalled on July 31, more than three months after his abortive first stint in the majors ended, Holliday made an immediate impact by hitting a 439-foot grand slam off the Blue Jays’ Yerry Rodríguez for his first major league home run. He went hitless the next day, then peeled off three straight two-hit games against the Guardians; in the last of those, on Sunday, he hit a solo homer off Gavin Williams. He homered in his next two games as well, with a solo shot off the Blue Jays’ Chris Bassitt on Tuesday and a two-run blast off Ryan Burr on Wednesday:

That last homer turned a 3-2 deficit into a 4-3 lead in what wound up as a 7-3 victory. It also made Holliday the youngest player in AL history to homer in three consecutive games, at 20 years and 247 days old. His streak ended on Thursday with an 0-for-4 night against the Blue Jays, though Holliday did collect an RBI for the sixth game in a row, driving in a run on a ninth-inning groundout.

Like teammates Adley Rutschman in 2022 and Gunnar Henderson in ’23, the 20-year-old Holliday entered the year as the consensus no. 1 prospect. He appeared on track to break camp with the Orioles given a strong performance in the Grapefruit League, but the team instead optioned him to Triple-A Norfolk in late March, with his limited experience at that level (18 games last year), at second base (26 games), and against upper-level left-handed pitching all apparently factoring into decision, as did a roster crunch.

Some of that may have been typical front office lip service, however, as Holliday didn’t have to wait long for his first opportunity. With a stretch of facing five lefty starters in their first nine games behind them, the Orioles called up Holliday, who had hit .333/.482/.595 through his first 10 games at Norfolk. He debuted on April 10 with an 0-for-4 showing against the Red Sox, striking out twice but driving in a run on an RBI groundout. Unfortunately, things didn’t get much better; in fact, he was utterly overmatched, going 2-for-34 with two walks and 18 strikeouts in 10 games. While general manager Mike Elias and manager Brandon Hyde both publicly expressed confidence that Holliday would still become an impactful player soon, the Orioles optioned him to Norfolk on April 26.

“I think the bright side of this is he got very intense, very specific feedback from major league pitching,” Elias said at the time. “He’s a brilliant talent and a very sharp kid, and I expect he’s going to go implement those adjustments really quickly. But we felt that Triple-A and steady playing time in Triple-A was the place for that.”

Back at Norfolk, Holliday put up respectable numbers (.252/.418/.429) before missing two weeks in June due to elbow inflammation. Just days after he returned, colleague Eric Longenhagen noted some disconcerting aspects of his performance:

In a way, the IL stint was comforting because it offered a potential explanation for why Holliday’s performance and ferocious bat speed had tapered off a bit. Holliday’s spray chart shifted away from his pull side and moved toward left field and the third base line in the weeks leading up to his shelving. He was inside-outing lots of contact the opposite way, including pitches on the inner third of the plate that he typically turns on, and it was taking what appeared to be an uncomfortable and excessive amount of effort for him to swing hard.

Once he came off the IL at Norfolk, Holliday showed more power, but he was limited to DH duty until after the All-Star break. On July 29, a day before the trade deadline, Longenhagen further noted some defensive concerns, writing in his Top 100 Hitting Prospects Update, “He looks rather rusty and uncomfortable, if not still compromised to some extent. He’s making a lot of routine plays look harder than they need to be, and the quality of his hands has backed up.”

“[H]e does look like a 20-year-old lost in a sea of adults, and it’s become tough to make a strong argument for Holliday over James Wood right now,” concluded Longenhagen, who downgraded Holliday from a 70 FV prospect to a 65, which allowed Wood to take over the top spot on The Board.

While all of that was going down, so were Orioles infielders. On July 23, Mateo — who has made a team-high 52 starts at second base plus three at shortstop and two in center field — injured his left arm in a collision with Henderson. The 29-year-old infielder was diagnosed with an elbow subluxation and placed on the IL, while prospect Connor Norby was recalled from Norfolk. Five days and five starts at second base later, Norby was traded to the Marlins in a deal for Trevor Rogers; that same day, Mateo was transferred to the 60-day IL.

The next day, Holliday returned to the majors, but immediately before he hit his grand slam, Rodríguez drilled Westburg — who has made 64 starts at third base, 35 at second, and one at shortstop — in the right hand with a 95-mph fastball. The 25-year-old infielder suffered a fracture, interrupting a breakout season in which he’s hit .269/.317/.497 (129 wRC+) with 18 homers and earned All-Star honors. The hope is that he’ll be back in mid-September, in time to get tuned up for the postseason, but even given the Orioles’ depth, his absence looms large.

Those injuries have cleared a path for Holliday to get a long look at second base. As he’s still climbing out of the statistical hole he dug in April, his overall slash line looks pretty grim (.177/.239/.387, 76 wRC+ in 67 plate appearances), and the sample sizes for his splits are even smaller. But with the caveat that these numbers mostly haven’t reached the point of stabilizing, within those numbers we can at least discern some positive trends:

The first big thing to note beyond the fact that he’s been productive since returning is that Holliday has gotten his strikeout rate under control. Mind you, he has struck out at least once in all 18 of his games, putting him one short of Austin Jackson’s 2010 record of 19 consecutive games with strikeouts to start a career.

The second thing to note is that Holliday has taken a more aggressive approach at the plate since returning. While he’s swinging at more pitches both in and out of the zone, he’s coming up empty less often:

I don’t think there’s much to be gleaned from his pitch-type splits since returning given that Holliday has seen fewer than a dozen examples of every offering besides four-seamers and sliders. His four homers have each come against a different pitch (four-seamer, slider, curve, cutter), so that’s something.

The third thing to note is that Holliday’s contact since returning has been loud:

Of Holliday’s 20 batted balls since returning, 14 have been hard-hit balls with exit velocities of 95 mph or higher, 11 of them 100 mph or higher. Granted, six of those hard-hit balls have been grounders (five of at least 100 mph), but he’s turned three into singles, and even with his high groundball rate, he’s barreled half a dozen balls in this short time. His total of 36 batted balls is still short of the point of stabilization, but those barrel and hard-hit rates would both rank among the top half-dozen if they were maintained over (much) larger samples.

One more note on batted balls: Where Longenhagen was concerned with how often Holliday was hitting to the opposite field, his 55% pull rate and 20% oppo rates since returning — not to mention the fact that all four homers were to his pull side — suggest he’s moved past that issue. As for his defense, Holliday did make a nice pick to start what upon review proved to be a game-ending double play on July 31, but the jury is still out on his transition.

It’s premature to suggest Holliday has everything ironed out, but at the very least, he’s given the Orioles a most welcome boost. That still leaves them with numerous issues, however. Prospect Coby Mayo, who is no. 12 on The Board, was called up on August 2 to play third base, but so far he’s 0-for-13 with eight strikeouts; this week’s signing of free agent J.D. Davis, who hit just .218/.293/.338 (85 wRC+) for the A’s and Yankees, to a minor league contract suggests Mayo’s leash may not be long. Heston Kjerstad, who landed on the 7-day concussion IL after being beaned by a 97-mph Clay Holmes fastball on July 12, is back on the IL with lingering concussion symptoms after going just 2-for-18 upon returning. The reserve outfielder fitting into his roster slot, Austin Slater, has hit just .205/.331/.250 (77 wRC+) in his three-team odyssey this year.

More concerning is the rotation, which has already lost Kyle Bradish and John Means to Tommy John surgery and Tyler Wells to UCL brace surgery, and which has been lit for a 5.19 ERA and 4.66 FIP since the start of July, and has a 5.10 ERA even after the acquisitions of Rogers and Zach Eflin. Earlier this week, Grayson Rodriguez landed on the IL due a mild right lat strain. “He’s going to miss some time,” said Hyde. “We’re going to shut him down for a little while, get him some rest and recovery, get him some rehab. I think we’re optimistic about it.” His absence leaves a rather unimposing rotation behind ace Corbin Burnes, with Rogers and Eflin joined by Dean Kremer and swingman Albert Suárez. Of that group, only Burnes has an ERA below 4.00 since the start of July, with Kremer and Suárez well above 5.00. Fortunately for the Orioles, the Yankees have problems of their own, including a rotation that’s been even worse (5.59 ERA, 4.81 FIP) since the start of July, and unlike Elias, Brian Cashman did nothing to try to fix it at the deadline.

At this point, the division race looks like one between two rather flawed teams, and any advantages with regards to depth and player health could swing the balance. After a rough start, Holliday is not only fitting in but making an impact, and that can only help the Orioles.

On Thursday morning the White Sox sat at 28-89, recently having broken a 21-game losing streak. Which looks bad, but consider that Chicago is on pace to lose three more games than the 1962 Mets did. Or that over a comparable period — their last 117 games — the Vanderbilt Commodores football team is 40-77. (Vanderbilt’s past 117 games includes a winless season.) So the White Sox cashiered manager Pedro Grifol.

Yeah, that’ll fix the problem.

Immediately, thoughts turned to which unfortunate would be handed this hospital pass of a team. Especially because the traditional next man up for an in-season firing is the bench coach, and Charlie Montoyo (who has recent MLB managerial experience with the Blue Jays) was among the casualties.

As it turns out, the next skipper on this voyage of the damned, apparently, is Grady Sizemore. Read the rest of this entry »

The other week, I was talking to a friend as she fretted over her lack of productivity. Her struggle wasn’t with laziness or a lack of motivation, but rather a severe case of burnout, following her around the way No-Face follows Chihiro in Spirited Away. In the moment, I could see her desperately reaching for more energy to get through the day, like when the chip bag is nearly empty, so you bring it to your mouth and tilt your head back to suck down whatever salty goodness remains.

But instead of encouraging her to power through, I went a different way.

“Y’know, it’s okay to take a break.”

She laughed and said, “That’s what my therapist keeps telling me.”

If you’ve ever described yourself as a perfectionist or a people pleaser, or tied your self-worth to your measurable output, you know taking breaks can be hard.

Athletes learn from the beginning to idolize hard work. Hard work is the salve for every ailment. Wanna get stronger? Work harder. Wanna play better? Work harder. Wanna go pro? Work harder than everyone else. The hardest workers earn their own dedicated titles and recognition, separate from their actual production. Cal Ripken Jr.’s consecutive games played streak earned him the Ironman title. MLB gives out a Heart and Hustle award to whichever player’s heart tells him to hustle the hardest. And every year, we read stories about players and coaches who are the first to arrive to work each morning and the last to leave at night. Read the rest of this entry »
