If the Milwaukee Brewers are going to make a playoff run, they’ll likely have to take down the division-rival St. Louis Cardinals. The Brewers took a step toward that goal Tuesday, as the team reportedly called up top pitching prospect Jacob Misiorowski, according to ESPN’s Jeff Passan.
Misiorowski will be inserted into that rivalry immediately, as he’s expected to start against the Cardinals on Thursday.
The Brewers trail St. Louis by 1.5 games in the National League Central. Both teams are chasing the Chicago Cubs, who lead the division entering play Tuesday.

Armed with a fastball capable of touching 103 mph, Misiorowski shot up the Brewers’ minor-league system after being the selected in the second round of the 2022 MLB Draft. After appearing in the 2023 MLB Futures Game, Misiorowski found himself on top of prospect lists entering the 2024 MLB season.
He remained atop of those rankings entering the 2025 season and got off to an excellent start in Triple-A. In 63 1/3 innings, Misiorowski compiled a 2.13 ERA with 80 strikeouts.
During his time as a prospect, Misiorowski faced questions about his future role in the majors. He displays spotty control and has generally posted high walk rates in the minors. While he spent time in the rotation and bullpen in 2024, the Brewers have used him almost exclusively as a starter in 2025, signaling that they’ll give him a shot to start in the majors.

That could change depending on how Misiorowski and the rest of the Brewers’ rotation performs the rest of the way. Scouts look at Misiorowski’s 80-grade fastball — the highest grades scouts can give a pitch — and his strong curveball and see a possible high-leverage reliever. If Misiorowski struggles to get through lineups multiple times, it wouldn’t be a surprise to see the Brewers turn him into a bullpen weapon.
For now, Misiorowski will get an opportunity to start. While his debut will come against a team that has been surprisingly adept on offense, he should get multiple chances to prove he belongs in the rotation before the Brewers consider changing his role.
