Jacob Misiorowski set a new Major League Baseball velocity record on Monday, throwing 57 pitches at or above 100 mph during the Milwaukee Brewers’ 5-1 victory over the St. Louis Cardinals. The 24-year-old right-hander allowed just two hits, one walk, and a single run over seven innings.
Misiorowski threw 96 total pitches in the start. He hit 101 mph on 40 of those deliveries and scaled up to 102 mph on 22 of them. His fastball topped out at 103.4 mph three separate times. The performance broke the previous tracking-era record of 47 triple-digit pitches, according to a report detailing the historical context of his 12-strikeout outing.
Hunter Greene previously held the single-game mark, setting it in September 2022. The Cardinals were also the opposing team on the wrong end of that record-setting performance. Misiorowski tied Greene’s secondary record on Monday by recording nine of his strikeouts on pitches traveling at least 100 mph.
The lone run St. Louis managed came in the sixth inning. That sequence snapped Misiorowski’s consecutive scoreless streak at 29 1/3 innings. The streak stands as the third-longest shutout streak in Brewers franchise history, trailing only Teddy Higuera’s 32 innings in 1987 and Freddy Peralta’s 30 innings in 2025.
The outing lowered Misiorowski’s season ERA to 1.83. He is the first pitcher in the majors to reach 100 strikeouts in the 2026 campaign. He has now thrown 22 pitches of at least 103 mph in his career as a starter, a mark no other MLB starter has exceeded two during the tracking era.
