Milwaukee Brewers pitcher Jacob Misiorowski set a World Series record with a 103.5 mph fastball on his opening pitch.
Harlingen Weslaco Brownsville McAllen, TX, October 23, 2026 —
Milwaukee Brewers pitcher Jacob Misiorowski set a World Series record by throwing a 103.5 mph fastball on his opening pitch, according to the information provided about the performance.
The pitch’s speed and its place as Misiorowski’s first pitch are the only details available about the moment. The summary identifies the mark as a World Series record but does not specify the record category, how the speed was measured, or the historical comparison used to establish it.
It also does not state when or where the pitch was thrown, which opponent the Brewers faced, or the result of the pitch. No details were provided about the remainder of Misiorowski’s appearance or the game’s outcome. Those details cannot be established from the information available.
The record-setting figure is 103.5 mph. The summary does not provide additional information about Misiorowski’s pitching role, the circumstances leading into the pitch, or whether the fastball resulted in a strike, a ball, or contact. It likewise does not include statements from Misiorowski, the Brewers, or other participants.
As reported in the summary, the notable point is that the record was set on the pitcher’s opening pitch rather than on a later delivery. Further context—including the date, the specific record being cited, and the source of the velocity reading—was not provided. Without those details, the available account is limited to the pitcher’s name, his team, the speed of the fastball, and its timing as his first pitch in a World Series game.
