Misiorowski’s 104.8 mph fastball sets reported postseason record
Yahoo Sports reports the Brewers starter surpassed Mason Miller’s 2025 mark, with a second pitch also faster than the previous record.
Milwaukee Brewers pitcher Jacob Misiorowski set a reported MLB postseason pitch-speed record with a 104.8 mph fastball, according to Yahoo Sports. It surpassed the previous mark of 104.5 mph, attributed to Mason Miller in 2025.
The broadcast displayed the pitch at 105 mph, while Yahoo Sports said its recorded speed was 104.8 mph. Misiorowski’s next pitch was reported at 104.6 mph, which would also have exceeded Miller’s mark.
The report says Misiorowski also holds the record for the fastest pitch by an MLB starting pitcher, at 105.5 mph, and the record for most pitches of at least 100 mph in a game, with 57 in an outing against St Louis in May 2026.
