Milwaukee Brewers pitcher Jacob Misiorowski set an MLB record for the most pitches over 100 mph in a single game on Monday, June 21, 2026 [3].

This performance solidifies Misiorowski as one of the most powerful arms in the modern era of baseball. His ability to maintain elite velocity over multiple innings puts him in a rare category of pitchers who can overpower professional lineups with raw speed.

The dominant start took place at American Family Field in Milwaukee, where the Brewers defeated the St. Louis Cardinals 5-1 [3]. Misiorowski, 24, utilized a combination of command and a fastball recorded at 103 mph [4].

While some reports highlight the record-breaking number of triple-digit pitches [3], other data emphasizes the quality of his heat. On May 8, Misiorowski threw seven of the fastest pitches by any starter in the pitch-tracking era [5].

Legendary pitcher Nolan Ryan took note of the young starter's trajectory. "He has a gift," Ryan said [1].

Despite the velocity, Misiorowski has faced some physical hurdles this season. He left two of his last three starts due to cramping [6]. When asked about those issues in May, Misiorowski said, "I’m not particularly concerned about the cramping" [2].

His current form suggests those early-season issues have not hindered his effectiveness on the mound. By blending high velocity with precision, he has become a cornerstone of the Brewers' rotation this season.

"He has a gift."

Misiorowski's record-breaking velocity represents a shift in pitching dynamics where triple-digit speeds are becoming more frequent but rarely sustained over a full start. If he can overcome the cramping issues that plagued his May outings, his rare combination of a 103-mph fastball and command could redefine the standard for starting pitcher dominance in the pitch-tracking era.
