FanGraphs Weekly Mailbag: June 28, 2025
On Wednesday afternoon, Paul Skenes and Jacob Misiorowski met in one of the most exciting pitching matchups of the season so far. Skenes is the best pitcher in baseball, while Misiorowski is the hardest-throwing starter. It was must-see TV. Michael Baumann covered the event in the most Baumann way possible, focusing on its hugeness — literally. “As impressed as I was with this display of firepower, awe at the future of pitching was not my primary takeaway. No, watching Skenes and Misiorowski do battle made me feel uneasy,” Baumann wrote. “See, these guys are huge.” He followed those words up with one of my favorite paragraphs in the illustrious annals of baseball writing:
This is too big. Both of them. The modern baseball field was designed for Scots-Irish immigrants with bad childhood nutrition and kidney disease. When 5-foot-11 Honus Wagner was the biggest, strongest player in the league. If you told the founding fathers of baseball that one day ballplayers would get so big they couldn’t borrow pants from Dave Bautista… well first of all, I guess you’d have to explain Dave Bautista to Abner Doubleday and Alexander Cartwright. You get my point.
I’m not going to write about the Skenes-Misiorowski matchup. What more could I possibly add? Instead, I will begin this week’s mailbag by answering a question about Misiorowski’s earth-shattering velocity. Before I do, though, I’d like to remind all of you that while anyone can submit a question, this mailbag is exclusive to FanGraphs Members.

I would love to see Davy Andrews take another look at the Kwan, Perdomo, Robles problem (linked above) now that we have MiLB Statcast data available.
Consider players like Matt Shaw. Shaw’s MLB #: 136 events, AEV 82.7 (1st percentile), HH% 25% (2nd percentile). Shaw’s AAA #: 181 events, AEV about 89, HH% around 40%, both near MLB average. Shaw is half way through one MLB season and his numbers may change, but my question is more about defining his “problem”. With MLB data alone, we might conclude Shaw’s problem is not hitting the ball hard enough. Considering AAA data, perhaps the primary problem is a struggle against MLB pitching. The two problems are not mutually exclusive. Perhaps the problem also relates to the balls that aren’t hit hard (as in Kwan vs Perdomo, from the article). I am wondering to what degree the AAA data might help to define the problem (or not).
