Milwaukee Brewers right-hander Jacob Misiorowski set a World Series velocity record by throwing a 103.5 m.p.h. fastball on the very first pitch of Game 1 against the Tampa Bay Rays at American Family Field, surpassing Aroldis Chapman’s previous mark while helping the Brewers secure a 3-2 victory.
Fantasy & Market Impact
- Misiorowski anchors fantasy rotations as an elite strikeout asset, backed by a major-league leading 252 regular-season strikeouts and a 1.80 ERA.
- Bettors monitoring World Series futures saw Milwaukee secure a crucial Game 1 edge, though pitching plans beyond Logan Henderson as the likely Game 2 starter remain unconfirmed by the club.
- The young right-hander’s historic velocity metrics cement his valuation as a premier foundational arm in keeper and dynasty formats.
Shattering Fall Classic Radar Guns
The record-breaking offering occurred on Friday night, clocked at 103.5 m.p.h. by MLB’s Statcast system after registering at 103.4 m.p.h. on the stadium video boards. Misiorowski vowed prior to the matchup to bring Charizard-like energy to the mound. The leadoff fastball to Tampa Bay leadoff hitter Yandy Díaz was taken for a ball above the strike zone, but it immediately eclipsed the previous World Series mark of 103.2 m.p.h. set by Aroldis Chapman for the Chicago Cubs in the ninth inning of Game 2 in 2016.

Beyond breaking Chapman’s overall Series record, the 24-year-old right-hander comfortably outdistanced the previous high by a starting pitcher since Statcast tracking began in 2008. Noah Syndergaard held that previous starter benchmark at 101.1 m.p.h., having thrown a pitch to Kansas City’s Ben Zobrist in the first inning of Game 3 in 2015.
Relentless Heat Over Five Innings
Misiorowski did not merely touch triple digits once and settle down. He reached 100 m.p.h. with 38 separate pitches during the outing, obliterating Chapman’s previous Series high of 24 such pitches from Game 5 of 2016. The appearance marked the Brewers’ first World Series appearance since 1982 and only the second in franchise history.
| Pitcher | Team | Opponent | Year | Fastest Pitch (m.p.h.) |
|---|---|---|---|---|
| Jacob Misiorowski | Milwaukee Brewers | Tampa Bay Rays | 2026 | 103.5 |
| Aroldis Chapman | Chicago Cubs | Cleveland | 2016 | 103.2 |
| Noah Syndergaard | New York Mets | Kansas City | 2015 | 101.1 |
The velocity barrage included 30 pitches at 101 m.p.h. or higher, 11 at 102 m.p.h. or more, and three reaching the 103-plus m.p.h. threshold. Despite generating just seven swings and misses—five on his four-seam fastball—Misiorowski navigated five innings, allowing one run and four hits with three strikeouts before departing with a 2-1 lead.
Historical Precedents and Upcoming Matchups
The historical context stretches back through his dominant 2026 campaign. Misiorowski threw 1,115 pitches at 100 m.p.h. or higher during the regular season, shattering Jordan Hicks’ previous high of 673 set with St. Louis in 2018. His absolute peak velocity this year reached 105.5 m.p.h. against the Chicago Cubs on June 27, narrowly trailing Chapman’s regular-season record of 105.8 m.p.h. established in 2010.
Tampa Bay eventually broke through against him in the fourth inning when Jonathan Aranda walked, advanced on Junior Caminero’s double, and scored on a grounder by Liam Hicks. However, Milwaukee preserved the advantage to claim the opening game of the Fall Classic. The Brewers’ subsequent rotation plans beyond Logan Henderson remain unannounced as the series continues.
