Jacob Misiorowski broke the record for fastest World Series pitch with the very first offering of this year's Fall Classic, a 103.5 mph fastball from the Milwaukee Brewers' fireballer to the Tampa Bay Rays' Yandy Díaz on Friday night.
Aroldis Chapman of the Chicago Cubs set the mark for a Series pitcher at 103.2 mph in the ninth inning of Game 2 in 2016, an offering that resulted in a groundout to second by Cleveland's Coco Crisp.
