Over the weekend, a friend of mine asked if ABS challenge data gets incorporated into WAR. (I have extremely cool friends.) It doesn’t, and I explained that while an individual challenge can absolutely change the course of an inning (or a game, or even a season), a single ball-strike call is of negligible run value out of context. If anything, we should be adding challenges to WPA, not WAR, except WPA only gets calculated on a per-plate-appearance basis, rather than a per-pitch basis.
At any rate, challenges aren’t like catcher framing in the early days. In 2008, the first year for which we have framing data, the difference between the best framer in baseball (Brian McCann) and the worst (Ryan Doumit, the poor guy) was 97.7 runs. At 10 runs per win, well, you can do the math on your own. Read the rest of this entry »
Even by the standards of his recent, injury-marred seasons, Max Scherzer’s 2026 campaign has been a rough one. The 42-year-old righty has made two trips to the injured list, and through the end of July had taken just seven starts and allowed more than a run per inning. Even on a Blue Jays team destined to be retooled ahead of the trade deadline, he was clearly in no shape to be any contender’s hired gun. Nonetheless, Scherzer’s last two starts have been bright spots, and on Saturday evening, he notched career strikeout 3,516, officially moving him into the all-time top 10.
Scherzer wasn’t the only pitcher who reached a strikeout milestone this weekend. Aaron Nola, who started for the Phillies opposite Scherzer at Citizens Bank Park, collected his 2,000th career strikeout. Elsewhere, in a matchup that pitted the third- and fourth-ranked pitchers on the active strikeouts leaderboard, namely Chris Sale and Gerrit Cole, the latter notched his 1,000th strikeout since joining the Yankees. Then on Sunday, Jacob Misiorowski became the first pitcher to notch his 200th strikeout of the season.
I’ll get to all of those pitchers, but first Scherzer. After holding Philadelphia scoreless through five innings while scattering three hits and striking out three, he returned for the sixth inning and faced leadoff hitter Kyle Schwarber, who entered the day as the major league leader in strikeouts (172) and who on June 10 in Toronto was the victim of Scherzer’s career strikeout no. 3,500. That outing was the only major league start Scherzer took between April 24 and July 27; first he was sidelined by a combination of forearm tendinitis and left ankle inflammation, and then — after lasting just 3.1 innings against the Phillies while being tagged for five runs — a bout of back spasms. He was in much better shape on Saturday evening, and in his previous two plate appearances against Schwarber had limited the slugger to a groundout and an infield single.

“There’s no weekend.” I remember thinking that night after night in the early going, as I held Derek Jr. in my arms while everyone else slept. There’s no weekend. In baseball, they talk about the grind of a long season. Even the off days are rarely actual days off because there’s so much travel involved. Everyone’s banged up. Everyone’s fighting to get proper nutrition and enough sleep. I don’t know if it’s true, but I remember reading somewhere that ballplayers consider a day game followed by a night game essentially a day off, just because they finally get an evening to themselves. Anyway, that’s what I used to think in the dark in the wee hours of the morning, feeling new aches in my arms or my neck or my back or all three. There is no weekend. There is no day off. Saturday has come and gone, and I’m up in the middle of the night with Derek Jr. Sunday will come, and I’ll again be up in the middle of the night with Derek Jr. Read the rest of this entry »
Davis Martin had a first inning to forget on Tuesday. Pitching at Fenway Park, the Chicago White Sox right-hander was torched for six runs by a scorching-hot Red Sox team that went on to prevail 14-2. He settled down after the tumultuous frame — only one more runner crossed the plate before Martin departed in the sixth — but by then the damage was done.
What happened in the fateful first inning? I asked him that question the following day, but before we get to his thoughts, a quick recap:
With two on and one out, Willson Contreras singled home a run. Two batters later, Caleb Durbin launched a grand slam. Jarren Duran then followed with a solo shot on Martin’s 20th pitch of the game.
The hurler’s take?
“First, there is a lot to be said about how good this Red Sox team is, and what they’ve been doing,” said Martin, who is 9-6 with a 4.13 ERA and a 3.48 FIP over 122 innings on the season. “We studied the scouting report, and there weren’t a lot of pitches that I would want to take back. But yeah, I felt that they were one step ahead. They were doing a really good job of keeping me off balance.”
Red Sox hitters had clearly been more aggressive than the White Sox expected. Half a dozen runs coming on 20 pitches thrown to seven batters is notable, especially when you consider that Contreras saw six of them. His at-bat was arguably the key to the inning. After fouling off consecutive two-strike offerings, the slugger got his RBI knock on a breaking ball that was well wide of the plate. Read the rest of this entry »
On Friday, the Boston Globeran a story by Red Sox beat writer Alex Speier on the concept of momentum. I can hear the collective groans of our Members now. Haven’t we gone over this enough? We’ve already established that there’s no such thing as momentum! Or, if there is, its effect is minimal. Our readers would be the first to point out that the month-and-a-half long surge up in Boston is mostly a matter of a talented, drastically underperforming Sox team experiencing some serious positive regression, bringing its overall record back up to about where we expected it to be all along. I get that, of course. We cannot conclusively prove the effect of momentum in baseball — and it’snotforlackoftrying — and so therefore cannot definitively say that it exists. Yet when it comes to the Big Mo, a palpable feeling rather than a tangible metric, I tend to subscribe to what I call the Robert Graysmith Theory: Just because you can’t prove it, doesn’t mean it isn’t true.
What’s interesting about Speier’s piece is that he, along with Globe staffers Julian Benbow and Daigo Fujiwara-Smith, looked for data to support the impact of momentum on winning and losing streaks. Speier, an analytically savvy writer, said in his Bluesky post sharing the story that he “was skeptical” that their search would lead to anything. Instead, he was astonished to learn that, as he writes in the story, “A Globe analysis of Retrosheet data that includes the outcome of every MLB game from 1901 through 2025 revealed a striking pattern: The longer a winning streak lasts, the higher a team’s winning percentage in the next game.” The inverse is true for losing streaks. Speier mentions several factors unrelated to momentum that help to explain why “baseball streaks tend to be somewhat self-sustaining,” most notably that team quality probably plays a major role in enduring stretches of winning or losing. That alone is enough of a reason to maintain any skepticism you may have toward the idea of momentum. But at the same time, we should acknowledge that many players believe in the power of momentum, and if that belief influences how they feel, and how they feel contributes to how they perform, then it stands to reason that momentum — or at least, their belief in momentum — has at least some impact on performance.
That’s the last we’ll be discussing momentum here, though I’d encourage you to read the entirety of Speier’s story after you’ve finished reading this mailbag. Instead, today we’ll be answering your questions on players to be named later, the teams that most improved (or diminished) their 2027 playoff odds with their moves at this season’s trade deadline, and where Pete Crow-Armstrong would stack up on the five-star catches leaderboard if we had Statcast data going back through baseball’s history.

With apologies to Tarik Skubal and the Dodgers, for my money the most eye-catching deal ahead of Monday’s trade deadline was the Red Sox acquiring Adley Rutschman in a six-player blockbuster with the Orioles. Not only did a switch-hitting All-Star catcher move from one Wild Card contender to another, but he did so within the same division — and he’s more than a rental, with one more year of arbitration eligibility before he reaches free agency. Though he’s currently on the injured list due to inflammation in his left wrist, Rutschman is reportedly nearing a rehab assignment, and once he returns, he should provide a substantial upgrade for a team whose catchers landed on my Replacement-Level Killers list a few weeks ago.
Rustchman wasn’t the only prominent catcher on the move to a contender on Monday, as the Marlins tradedLiam Hicks to the Rays, but he’s a part-time backstop whose hitting makes him a useful DH and first base option as well. While the concurrence of his being dealt illustrates that trading for a catcher on the fly in the midst of a playoff race isn’t unheard of, such moves do stand out. They’re not to be undertaken lightly because of the weighty responsibility that falls on a catcher’s shoulders in terms of quickly having to build relationships with a new pitching staff to understand repertoires, situational preferences, and interpersonal dynamics. Odds are that those newcomers are also expected to provide more offense than the catchers they replaced, because offensive slumps often spur teams to make such changes. Read the rest of this entry »

We’re trying to decide whether Derek Jr. is ready to move up from size two diapers to size three. I mention that we’ve still got a couple size one diapers left in the diaper bag. Maybe it’s not too late to use them up so they don’t go to waste. “Those size one diapers,” replies my wife, whose gorgeous, haunting debut novel comes out next fall, “would not fit one of her butt cheeks.”

Similarities Between My Daughter and Professional Baseball Players:
They’re disturbingly young.
They love spending time at the park.
They’re incapable of keeping their saliva in their mouths where it belongs.
They have shockingly thick forearms.
They frequently dirty their uniforms.
They’re constantly besieged by photographers.
They have a carefully monitored nutrition regimen.
I thought I’d left this life behind. I thought my We Tried tracking days were behind me. I spent the past week covering trades that happened. Real trades, where one player (or two players, or three players, or a theoretical pile of international bonus pool money) moved from one team to another in exchange for one other player (or two other players, or, well, you get it). But just when I thought I was out, the Brewers pulled me back in. Of all teams, the Brewers! I started tracking We Trieds following the 2024 season, and over two offseasons, Milwaukee put up two goose eggs. The Brewers never gave me a single We Tried to track. Now they’ve had such a dramatic We Tried that they’re dragging me kicking and screaming out of We Tried retirement. What a world. Oh, and the Red Sox roped me back in too, because of course they did. But let’s start in Milwaukee.
As you might have learned from Michael Baumann, the Brewers were considered a real contender to land Tarik Skubal. That alone does not a We Tried make, but on Tuesday, MLB.com’s Adam McCalvy spilled all sorts of beans about their ace chase. McCalvy talked to “multiple club officials” and found the Brewers uncharacteristically forthcoming. He learned that although top overall prospect Jesús Made was off limits, the Brewers offered shortstop Luis Peña, whom we have ranked 26th overall on our updated Top 100 Prospects list, and two other position player prospects. One of those other prospects was also a Top 100 talent, which, depending on whose top 100 you’re talking about, could mean Brady Ebel, Jett Williams, Josh Adamczewski, or Luis Lara (though probably not Lara, as the Brewers signed him to an extension in June). That’s quite a lot of specifics.
A friend sent this article to me within an hour of its publication. It hits all the We Tried hallmarks. It lays out the offer the Brewers made, speculates on the players included and the players the Dodgers would have liked them to include. As I read on, I couldn’t help myself. I knew I’d have to get back in the game. Read the rest of this entry »
That’s a tough question. Whatever answer you come up with will certainly say just as much about your methodology as the pitch itself. That’s OK. We’re open-minded people here, and there’s more than one way to approach this problem. Read the rest of this entry »
Ranked and briefly analyzed below are the prospects who have been traded during the loosely defined “2026 deadline season,” which for simplicity’s sake we consider all of July. Most of the deals these prospects were a part of have been analyzed at length on this site. An index of those pieces can be found here; you can also click the hyperlink in the “Trade” column below, which will take you to the relevant article. We’ve moved all of the 35+ FV and above players listed here to their new orgs over on The Board, so you can click through to see where they rank among their new teammates and read their full scouting reports.
