Jacob Misiorowski Sets MLB Record with 57 Triple-Digit MPH Pitches in Dominant Win Over Cardinals

On Monday, Jacob Misiorowski threw a seven-inning, 5-1 win over the St. Louis Cardinals, delivering 57 pitches at 100 mph or higher—the most in a game since pitch-tracking began in 2008. He struck out a career-high 12 batters, allowed two hits, one walk and a single run.

Misiorowski entered the start after a May in which he logged 31  1/3 innings, gave up one earned run, struck out 49 and walked six, posting a 0.29 ERA. This season he holds a 1.83 ERA, 0.83 WHIP, 100 strikeouts (league-leading) and a 1.88 FIP. His fastball averages 99.7 mph, reached 100.7 mph last month, and makes up 61 % of his pitches, ranking in the 99th percentile. The prior record for 100-mph pitches in a game was 47 by Hunter Greene in 2022.

The outing strengthens Misiorowski’s Cy Young candidacy, placing him alongside Spencer Strider and Jacob de Grom as one of the few pitchers with 100 Ks and <=50 total bases early in a season. Sustaining triple-digit velocity deep into games challenges traditional pitcher endurance expectations and may shape future conditioning. The performance also fuels speculation that he could reach 104-105 mph, a speed achieved by only a handful of relievers.

Pat Murphy called the game “magnificent” and among the best he has seen. Andrew Vaughn praised Misiorowski’s command, saying the pitcher’s focus on throwing strikes is key. The organization highlighted his offseason lower-body training as a factor in maintaining velocity.

Milwaukee will finish the three-game series with the Cardinals, and Misiorowski is slated to start the next game. Observers will watch if he can maintain his velocity and remain a Cy Young contender.
