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.”

On Sunday evening, Camilo Doval stepped to the mound without his usual light show. He showed the range of his game right away – after striking out the first two batters he faced, he walked Greg Jones, who promptly stole both second and third. Then Nolan Jones ripped a scorching line drive to center for a triple, Elehuris Montero stroked a line drive single, and two runs had scored just like that. To make matters worse, this wasn’t even against the Rockies – it was against the Triple-A Albuquerque Isotopes.
It’s hard to wrap your head around Doval’s sudden fall from ace closer to minor leaguer. He debuted in the magical 2021 season, picked up closing duties at the tail end of that year, and looked like one of the best relievers in the sport almost immediately. In 2022 and ’23, he pitched to a 2.73 ERA and 2.87 FIP. He was wild at times, overpowering at others, and impossible to square up in every iteration. When you have a 100 mph cutter and a tight 90 mph slider to throw off of it, you don’t need much else. He was fifth in baseball in saves, ninth in reliever WAR, 10th in innings pitched among relievers; in other words, he was a one-man back-of-the-bullpen for the Giants.
One thing always bothered me about Doval, even when he was dominating the opposition for the last two years: His cutter doesn’t cut correctly. That sounds nonsensical, or at best like a weak nitpick. But here, take a look at his cutter as compared to Emmanuel Clase’s best-in-class offering, using our pitch-type splits:

The “cut” in a cutter refers to glove-side movement. A good cutter looks like a fastball out of the hand before the spin takes over; then it veers sharply away from the four-seam path that hitters have spent their whole lives tracking. It’s not just a matter of how differently shaped the cutter is from the rest of a given pitcher’s arsenal – just ask Mariano Rivera. Instead, it’s more about defying the brain patterns batters have built up over decades of playing baseball. That’s just not where a fastball should go, and so hitters either swing fruitlessly over it or, in the case of opposite-handed batters, end up breaking their bats when the pitch bores in on their hands.

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.
Ben Lindbergh and Meg Rowley banter about how Jorge López has done since his release from the Mets, Juan Soto‘s underrated dominance, George Springer’s post-replay rage, whether the Rangers are a candidate for Angels-esque August waiver shenanigans, whether Dodgers pitchers are particularly prone to Tommy John surgeries, and the divisive value of Salvador Perez. Then (41:56) they welcome high-school student Bailey Hall, who won an award for the best poster presentation at SABR 52, for a guest Stat Blast about scoring after leadoff walks vs. leadoff singles, followed by (1:10:19) a postscript on recent team TJ totals.
Thanks to the trade deadline, this is a quiet time of the year for transactions, but baseball’s injured list is always hopping, and Tuesday was sadly no exception. First came the announcement that Dodgers pitching prospect River Ryan, our 21st-ranked prospect on the Top 100, would require Tommy John surgery, ending his 2024 season, and at best keeping him out for the vast majority of 2025. Not to be left out of the UCL injury party, Jazz Chisholm Jr. injured his left elbow on a slide into home plate on Monday night. The exact severity of Chisholm’s injury is still unknown, but with the season rapidly reaching its conclusion, any significant time on the shelf could imperil his ability to help the Yankees in their playoff push this year.
Chisholm was easily the biggest addition the Yankees made at the deadline, a flexible offensive player who the team hoped would bring some emergency relief to an extremely top-heavy offense that has received an OPS in the mid-.600s from four positions (first base, second base, third base, and left field). And Chisholm was more than fulfilling that expectation, with seven home runs in 14 games on the back of a .316/.361/.702 slashline. As noted above, the full extent of his injury isn’t yet known, but in a tight divisional race with the Baltimore Orioles (and with a playoff bye at stake), every run is precious. The Yankees have had a curious amount of misfortune when it comes to the health of their deadline acquisitions in recent years; between Frankie Montas, Scott Effross, Lou Trivino, Andrew Benintendi, and Harrison Bader, you might get the idea that they mostly acquire medical bills in their trades.

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 »
Yates entered Tuesday night’s contest against the Boston Red Sox with an ERA of 1.04; that mark is second among big league relievers, behind only Emmanuel Clase (another favorite of mine). It’s also a career best for Yates, which is more surprising than it would be for most pitchers. Yates already has a season with a microscopic ERA on his CV: 2019, when he posted a 1.19 ERA in 60 2/3 innings, with a strikeout rate of 41.6% and a walk rate of 5.3%. Pitchers who produce even one season of that quality are vanishingly rare; pitchers who produce two are almost unheard of. 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.

Ben Lindbergh and Meg Rowley banter about the 30th anniversary of the 1994 strike and how nice it is not to have the season end in August, the unusual extension of Victor Robles, Tanner Rainey, Patrick Corbin, and the remnants of the 2019 Nationals, Will Wagner and whether the debuts of sons of big leaguers make us feel old partly because big leaguers have kids earlier than average, how MLB could accommodate the 2028 Olympics, changes in BBWAA awards voting patterns and the suddenly competitive MVP races, the return of Mookie Betts, whether the end of pitcher hitting affects pitcher pitching, Seth Lugo vs. Tarik Skubal, Jarren Duran’s suspension, his heckler, and how well one could hit a baseball with a tennis racket, and listener-suggested additions to the Hierarchy of Versatility.
