The best thing Jacob Misiorowski did against the Dodgers had nothing to do with the fastball everybody shows up to see. Jacob Misiorowski vs. the Dodgers turned on a slider, thrown in the worst possible spot on the field, with the bases loaded and Shohei Ohtani's lineup leaning in. The reporting out of Los Angeles frames it exactly right: a dominant fastball has made him one of the most exciting pitchers in baseball across the past two seasons, and it was the breaking ball that got him out of the jam.
I don't have his complete final line in front of me yet, so I'm not going to dress one up. What I have is the pitch he chose when the inning was on fire. That's plenty.
Who is Jacob Misiorowski and why does the slider matter
Velocity gets you to the big leagues. It does not keep you there. Every August in this sport, somebody's radar-gun darling learns that major league hitters do not need to catch up to the fastball, they only need to know it's coming. Eliminate a pitch, foul off the good ones, wait for the mistake. The Dodgers, of all lineups, are built out of hitters who have seen premium heat in every series they've played since spring.
So look at the situation again. Bases loaded is the exact moment a one-pitch pitcher gets found out, because it is the moment his own instincts betray him: throw the thing you trust, throw it harder, throw it again. Misiorowski went to the second-best pitch in the highest-stress at-bat of his night. Young arms don't usually do that. That's a tell, and it's the good kind.
checked the almanac: randy johnson threw the hardest fastball in baseball for years and was mostly a rumor of a pitcher until the slider showed up. then he was randy johnson. the heat is the ticket. the second pitch is the career.
What it means for the Brewers rotation
Milwaukee has spent the better part of a decade being the organization that turns arms into aces without ever paying retail, and Misiorowski is the loudest version of that project. A power arm who only overwhelms bad lineups is a fun summer. A power arm who can pitch backwards against the deepest lineup in the National League, in their building, in the middle of August, is a different asset entirely. That is the guy you hand a Game 2 to.
The context that makes this matter is repetition. Ohtani and that group will see him again, and again after that, and the great hitters do their damage on the second and third look. If the slider is a real pitch and not a good night's feel, the adjustments start running the other direction: Milwaukee's kid making the Dodgers guess instead of the Dodgers making him prove it.
What comes next for Misiorowski and the Brewers
The Brewers and Dodgers close the series Sunday afternoon in Los Angeles, 4:10 ET, and Misiorowski's work is already banked. What I'm watching from here is workload and repeatability: how deep Milwaukee lets him go as the innings pile up in a rookie-adjacent season, whether the slider holds its shape in cold late-season air, and how he handles a lineup that has now filed a full report on him.
The fastball will always be the highlight package. The slider is the part that decides how many Octobers he gets.
