Milwaukee Brewers starting pitcher Jacob Misiorowski set a new velocity record for a starter during a game against the New York Yankees [1].
The performance marks a significant shift in the physical capabilities of starting pitchers, who typically lack the explosive burst of relief pitchers. By maintaining elite speed over multiple pitches in a single frame, Misiorowski has established a new benchmark for power in the modern game [2].
During the first inning of the matchup on May 9, 2026, at American Family Field in Milwaukee, Misiorowski threw 10 pitches that exceeded 102 mph [1]. Some reports indicate that all 10 of those pitches were faster than 103 mph [2]. The fastest pitch of the inning was clocked at 103.6 mph [5], the hardest pitch ever tracked by MLB from a starting pitcher [5].
This performance surpassed the previous record for a starter, which was 103.2 mph set by Jordan Hicks on July 12, 2022 [5]. Misiorowski's repertoire during the outing included specific pitches recorded at 102.4 mph and 103.0 mph [1].
The velocity was matched by effectiveness on the mound. Misiorowski recorded 11 strikeouts during the game [2]. The right-hander's ability to sustain this level of speed while maintaining control against a high-profile lineup like the Yankees demonstrates a rare combination of raw power, and precision [2].
Misiorowski's effort was part of a broader attempt to push the boundaries of starting pitcher velocity [2]. While many starters rely on movement and sequencing, Misiorowski used overwhelming speed to dominate the New York hitters in the early stages of the contest [3].
“Jacob Misiorowski threw 10 pitches that exceeded 102 mph.”
This record challenges the traditional distinction between starting pitchers and closers. Historically, starters prioritize stamina and variety to navigate multiple innings, while high-velocity 'fireballers' are reserved for short relief appearances. Misiorowski's ability to deliver double-digit pitches over 102 mph in a single inning suggests a new era of athletic conditioning and arm strength that could force opposing teams to rethink their hitting strategies against starting rotations.
