Jacob Misiorowski Sets World Series Velocity Record in Game 1
Definitely flame,
said Milwaukee Brewers starting pitcher Jacob Misiorowski when asked what type of energy he would bring to the mound, according to MLB.com. Twenty-four hours later, the 24-year-old right-hander lived up to that promise by throwing a 103.5 m.p.h. fastball to Tampa Bay Rays leadoff hitter Yandy Díaz on Friday night, breaking the record for the fastest pitch in World Series history. sportsnet.ca reported that the pitch, taken for a ball above the strike zone, surpassed the previous Fall Classic mark of 103.2 m.p.h. set by Aroldis Chapman of the Chicago Cubs in 2016.
The opening offering at American Family Field established a new standard for velocity on baseball’s biggest stage since pitch tracking began in 2008. According to MLB.com, Misiorowski easily eclipsed the previous record for the fastest pitch by a World Series starting pitcher, which Noah Syndergaard held at 101.1 m.p.h. for the New York Mets in 2015.
Fastball Dominance Against the Tampa Bay Rays
Misiorowski did not ease into his first World Series appearance. Of his 13 pitches in the opening frame, 11 were four-seam fastballs, with ten registering above 101 m.p.h. and five topping 102 m.p.h. The flamethrower finished his night having thrown 38 pitches at 100 m.p.h. or harder, breaking Chapman’s 2016 high of 24 pitches in a single World Series game.

He’s been really good,
Brewers manager Pat Murphy said in an in-game interview with FOX, as reported by MLB.com. Just gotta give [catcher] William [Contreras] a ton of credit because William can jockey him through — he trusts William, and that relationship has paid off in the first three innings.
Tampa Bay managed to scratch across a run in the fourth inning when Jonathan Aranda walked, advanced on a double by Junior Caminero, and scored on a grounder by Liam Hicks. Despite that sequence, Misiorowski held the Rays to one run and four hits across five innings, striking out three batters and walking one before handing over a 2-1 lead to the bullpen. The Brewers ultimately held on for a 3-2 victory to take a 1-0 series lead in their first Fall Classic appearance since 1982.

Historic Season of Triple-Digit Velocity
The record-breaking opening pitch continuation of a season defined by extreme velocity.

Prior to Friday’s milestone, Misiorowski also set the postseason velocity record during the National League Division Series opener on Oct. 3 against the San Diego Padres, touching 104.8 m.p.h. to Fernando Tatis Jr. That eclipsed the previous playoff mark of 104.5 m.p.h. set by San Diego reliever Mason Miller.
