Milwaukee Brewer Jacob Misiorowski Sets Record with 104.5-mph Fastball in One-Hit Shutout
Jacob Misiorowski, the 25‑year‑old right‑hander for the Milwaukee Brewers, delivered a historic performance on Friday, June 13, 2026, at American Family Field. The pitcher threw a 104.5‑mph fastball – the fastest by a starting pitcher since velocity tracking began – and finished a 6‑0 win over the Philadelphia Phillies with a complete‑game one‑hit shutout.
Misiorowski’s outing was a textbook example of power pitching. He struck out 15 batters, allowed only one hit, issued no walks, and did not allow any runs. He faced the minimum 27 batters, aided by a double play in the third inning. The Brewers’ offense added six runs, giving the team a decisive victory.
The 104.5‑mph pitch was recorded by MLB’s advanced data system and confirmed by Sporting News and CBS Sports. It surpassed the previous record for a starter’s fastest pitch, which had stood since 2008. Misiorowski’s night also included 58 pitches that reached triple‑digit velocity, with a slowest fastball of 102.3 mph. He averaged 101.7 mph for the game and never reached a three‑ball count.
Statistically, the performance was remarkable. Misiorowski’s 15 strikeouts were the most by a pitcher in a single game for the Brewers in the 2026 season. He struck out 24 of 41 swings against his fastball, producing 26 whiffs versus 21 balls. The pitcher’s earned run average (ERA) for the season was 1.34, and he has allowed only one earned run over his last 54 innings, a stretch unmatched in MLB history since earned runs were first tracked in 1913.
The game was a “Maddux” – a shutout completed in fewer than 100 pitches – a rare feat that Greg Maddux popularized in 2012. Misiorowski’s 58‑pitch count places him among the few pitchers to achieve a Maddux in the modern era.
Misiorowski’s performance follows a strong start to his MLB career. He debuted in 2025 and earned his first All‑Star appearance the same year. The Brewers’ front office has noted his rapid development, and the pitcher is projected to become a free agent after the 2031 season if the club does not extend him.
The Phillies’ lineup featured veteran outfielder Kyle Schwarber, who was struck out on Misiorowski’s opening‑pitch fastball. The pitcher also retired rookie Justin Crawford in the ninth inning. Misiorowski’s comments, reported by ESPN, reflected his focus: “When I walked out for the ninth, my whole body shivered and the adrenaline really kicked in,” he said. He added, “There was no chance I was going to throw anything other than a heater right there.”
The Brewers’ victory moves the team to a 6‑0 record in the series against the Phillies. The win also improves the Brewers’ standing in the National League Central, where they are currently in third place. The Phillies, meanwhile, remain in the middle of the National League East standings.
Looking ahead, the Brewers will face the Chicago White Sox on opening day of the 2026 season. Misiorowski is expected to start that game, and the team’s management has indicated that his performance will be a key factor in the Brewers’ push for a playoff berth.
The record‑setting outing underscores Misiorowski’s potential as a franchise pitcher. If he maintains his velocity and command, he could become one of the most dominant starters in the league. The Brewers’ coaching staff will likely continue to refine his approach, focusing on pitch selection and stamina.
In summary, Jacob Misiorowski’s 104.5‑mph fastball and complete‑game shutout represent a milestone for both the pitcher and the Milwaukee Brewers. The performance sets a new benchmark for starting pitchers and adds a significant chapter to the Brewers’ 2026 season.
