Right-hander Jacob Misiorowski set the league on fire when he debuted in early June. The early returns for the lanky fireballer were so impressive that he earned an All-Star bid after just five games in the big leagues. Securing Misiorowski long-term is likely a priority for the Brewers, but those discussions haven’t gone too far at this point, per Curt Hogg of the Milwaukee Journal Sentinel. Hogg mentioned extension talks between the parties “have not occurred with any real momentum yet.”
Misiorowski tossed five hitless innings against St. Louis in his June 12 debut. He followed it up with a quality start against the Twins, and then five scoreless innings in a win over the Pirates. Misiorowski stumbled for the first time against the Mets (five earned runs in 3 2/3 innings), but bounced back by striking out 12 Dodgers. The 23-year-old pitched a scoreless inning in the All-Star game, earning a hold. A few rough appearances out of the All-Star break led to a 4.36 ERA for the season, though his 3.56 SIERA suggests he was more effective than that mark.
Extending Misiorowski is not without risk, considering his relatively light workload history and high-powered arsenal. The righty has accrued 233 2/3 innings in the minors since getting drafted in 2022. He added 66 innings in the majors this year. Misiorowski’s 129 1/3 innings between Triple-A and the big leagues in 2025 were a career high as a professional by more than 30 innings.
Misiorowski’s fastball averaged over 99 mph with the Brewers. His slider sat at a blistering 94.1 mph, while his changeup, if you can call it that, averaged 92.3 mph. The exceptional velocity on all of his offerings is part of the reason Misiorowski is effective, but busting the radar gun on every pitch can lead to a higher chance of injury.
Misiorowski won’t be arbitration-eligible until 2029. It’s tough to nail down what a potential extension would look like, given his lack of experience. The top contract handed out to a pre-arbitration pitcher is the six-year, $75MM deal Atlanta gave Spencer Strider back in 2023. Strider already had 134 big-league innings under his belt when he got the extension, including a dominant 2022 campaign that saw him post a 2.67 ERA with a 38.3% strikeout rate across 31 appearances. Eury Perez profiles similarly to Misiorowski from a talent and risk perspective, and he’s already had extension discussions with the Marlins. However, even at 22 years old, Perez has put up nearly three times as many MLB innings as Misiorowski.
With the Brewers reportedly worried about payroll, locking down Misiorowski at a discounted rate as soon as possible would be desirable. If he delivers a full season in the rotation with close to the results he had in 2025, the price is only going to go up. Hogg mentioned Milwaukee is “definitely willing to talk,” but that doesn’t mean they’ll be able to get on the same page with Misiorowski and his representatives.
