Milwaukee Brewers starter Jacob Misiorowski threw a first-inning fastball clocked at 105.5 mph against the Chicago Cubs, breaking his own record for the fastest pitch recorded by a starting pitcher in the pitch-tracking era, which dates to 2008, according to ESPN.
The pitch came in the first inning and immediately drew attention for the number on the radar gun. Misiorowski already held the previous record among starters, meaning he pushed his own benchmark further with the heater.
The pitch-tracking era record specifically applies to starting pitchers, a distinction that matters because relief pitchers, who often throw shorter stints at maximum effort, have historically led the leaderboards for raw velocity. For a starter to crack that ceiling consistently enough to set and then reset the record puts Misiorowski in unusual company.
The Cubs game provided the backdrop, but the fastball was the story.
