Jacob Misiorowski made an immediate and violent impact on the 2025 World Series, breaking the all-time velocity record with the opening pitch of Game 1 against the Tampa Bay Rays. The Milwaukee Brewers’ 24-year-old right-hander unleashed a 103.5 mph fastball on Yandy Díaz, a strike that Statcast confirmed as the fastest ever recorded in a World Series game. This historic offering instantly surpassed the previous benchmark of 103.2 mph set by Aroldis Chapman of the Chicago Cubs during the 2016 postseason, cementing Misiorowski’s status as the premier arm in baseball.

The raw power displayed by Misiorowski extended well beyond the record-setting first offering. He dominated the first inning by throwing fastballs on 11 of his 13 pitches, averaging 101.9 mph and touching 100 mph on 10 of those deliveries. Although two of his initial 10 pitches resulted in singles, the sheer velocity kept the Rays’ offense on the back foot, resulting in a scoreless first frame. This performance highlights a pitcher who has captivated the sport since his June 2025 debut, consistently delivering elite heat that rivals the game’s most feared arms.
This milestone also redefines the standard for starting pitchers in the modern era of pitch tracking. Misiorowski’s 103.5 mph throw easily eclipses the previous high for a Series starter, which stood at 101.1 mph when Noah Syndergaard of the New York Mets faced Ben Zobrist in 2015. As the Fall Classic unfolds, Misiorowski’s ability to sustain such extreme velocity will be the focal point for analysts and fans alike, signaling a new era of power pitching in Major League Baseball’s championship series.
