Jacob Misiorowski, a 24-year-old right-hander for the Milwaukee Brewers, has redefined the limits of what a starting pitcher can achieve, throwing 10 pitches at 103 mph or higher while striking out 11 batters over six innings in Friday's 6-0 victory over the New York Yankees. The performance establishes a new standard for velocity by a starting pitcher since Statcast tracking began 18 years ago, with three pitches reaching 103.6 mph—the highest velocity any starter has recorded in that span.
Misiorowski's dominance extends beyond raw speed. The young pitcher has already compiled an impressive résumé despite his age and experience level. He won head-to-head matchups with 2025 NL Cy Young Award winner Paul Skenes and three-time Cy Young winner Clayton Kershaw as a rookie, and he posted a 1.50 ERA in three postseason appearances last year. He called Friday's performance a top-three outing in his major league career.
Exceptional Consistency and Workload
The velocity Misiorowski displayed was remarkably consistent. All 10 of the pitches he threw in the first inning reached at least 102.4 mph. He reached 103 mph in the fifth inning on his 71st pitch of the night, concluding his appearance with consecutive strikeouts of Aaron Judge and Cody Bellinger. Of the 95 pitches he threw overall, 41 registered at 100 mph or higher, bringing his season total to 193 such pitches across eight starts.
Misiorowski leads the major leagues with 70 strikeouts and is the first pitcher to record at least 70 strikeouts through his first eight starts of a season since Atlanta's Spencer Strider in 2023. This was the second consecutive start in which he held his opponent scoreless. In his prior start against Washington, he threw 43 pitches at 100 mph or higher while working 5 1/3 shutout innings in a 6-1 victory, though he left that game due to a right hamstring cramp.
Perspective on Performance
When asked about his exceptional velocity, Misiorowski attributed the achievement to emotional investment in his craft. "It's just adrenaline. That's all it is. You start getting hyped up and you want to perform for your teammates behind you because they're doing the same for me. That's the whole goal," he said.
Brewers manager Pat Murphy emphasized that velocity alone does not determine success on the mound. "I'm not real keen on the velo, whether it's 100 or 103 or whatever. I just know if you don't have your other stuff or don't locate that in the zone or you're throwing it just down the middle, these guys can time up a jet plane. It's not just velo. There's a lot more to it," Murphy said. He also characterized Misiorowski's trajectory positively, noting, "Miz is interested in being great. And he's in that process of being great."
Misiorowski also reflected on mentorship he received from Hall of Fame pitcher CC Sabathia, who visited before the game. "CC's the man. It's really cool to meet a guy like that. He came in before (the game) and we got to really talk to him and pick his brain a little bit. It was fun," Misiorowski said.
When informed in the dugout about his historic velocity achievement, Misiorowski's initial reaction was measured. "I had no clue. I got told in the dugout. I went back and looked. I thought (the ball) was close, but, 'Oh, well.'" he said.
Brewers reliever Shane Drohan captured the exceptional nature of witnessing such performance. "It's hard to believe that you're going to see something you possibly haven't, with how much baseball we play. But when he's on the mound, it's possible," Drohan said.
Why This Matters:
Misiorowski's emergence as a dominant young pitcher with record-setting velocity reflects broader questions about player development, the role of mentorship, and institutional support in professional sports. His ability to achieve these milestones while maintaining focus on team success—rather than individual accolades—illustrates how collective investment in player development benefits organizations. The Brewers' cultivation of young talent like Misiorowski, combined with access to mentors like Sabathia and experienced management like Pat Murphy, demonstrates how institutional frameworks and intergenerational knowledge-sharing contribute to competitive success. For baseball stakeholders, Misiorowski's trajectory raises questions about sustainable performance, injury prevention, and the long-term health implications of consistently throwing at extreme velocities—concerns that require ongoing attention from team medical staff, league oversight, and player advocacy.
