Jacob Misiorowski Reportedly Sets World Series Fastball Record
Milwaukee Brewers pitcher Jacob Misiorowski set a new World Series record with a 103.5 mph fastball on his very first pitch in the Fall Classic.
Rochester, NY, October 23, 2026 —
Milwaukee Brewers pitcher Jacob Misiorowski reportedly set a World Series record by throwing a 103.5 mph fastball on his first pitch in the Fall Classic, according to the information provided.
The account identifies the pitch’s speed and says it came at the start of Misiorowski’s World Series appearance. It does not specify the game, the date, the opposing team, or the circumstances surrounding the pitch. It also does not provide details about the measurement method or the record’s historical scope.
The available information does not say whether the record refers to the fastest pitch thrown in a World Series, or to another defined category. No further statistics from Misiorowski’s appearance, including how many pitches he threw or how the game ended, were provided. The article therefore cannot establish additional details about his performance or the game’s outcome.
The reported 103.5 mph figure is the only numerical detail in the summary. No comments from Misiorowski, the Brewers, or league officials were included, and no independent confirmation or source for the record was provided. The pitcher’s first-pitch mark is the central claim, while the missing game and record context limits what can be established from the information available.
