Misiorowski fans 15, throws 104.5 mph in Brewers shutout

Jacob Misiorowski did more than overpower Philadelphia. He turned a 6-0 Brewers win into a benchmark performance, striking out 15, allowing one hit and throwing the fastest pitch by a starting pitcher since pitch tracking began, a 104.5 mph heater that set the tone from the first inning.

Misiorowski, 24, was untouchable at American Family Field. He threw 95 pitches, 74 for strikes, did not walk a batter and completed the first shutout of his major league career. Kyle Schwarber’s first-inning strikeout came on the 104.5 mph pitch, and Schwarber’s fourth-inning single was the Phillies’ only hit as Misiorowski faced the minimum 27 batters in a one-man shutdown.

The velocity was not a one-off flash. It came after Misiorowski had already touched 103.7 mph in his previous start against Colorado on June 7, the fastest pitch by a starter since tracking began in 2008 before he topped it against the Phillies. The bigger takeaway for Milwaukee is that the pitch was still there late, paired with enough command to keep one of the National League’s most dangerous lineups from building anything resembling a threat.

The performance carried unusual statistical weight. MLB.com said Misiorowski’s 15-strikeout shutout on 95 pitches was the most strikeouts in a Maddux since pitch counts began being tracked in 1988, and that Milwaukee had never produced a more dominant pitching performance. It also placed the outing among the greatest one-hitters in major league history, a label that fits a start where Philadelphia never advanced beyond a lone single.

The Brewers had entered the game 42-25, with the Phillies at 37-32, and the gap in the standings made the outing more than a highlight-reel fastball display. It read like a warning to the rest of the National League: Milwaukee may already have a starter who can control elite offenses without giving up the edge in velocity or the edge in command.

For Misiorowski, the night also landed on a milestone date, one year to the day after his major league debut on June 12, 2025. Brewers catcher William Contreras summed up the reaction in the dugout and behind the plate: “This is not a normal pitcher.”
