Record-Breaking Velocity on the Mound

Milwaukee Brewers rising star Jacob Misiorowski delivered an unprecedented performance during Friday's game against the New York Yankees. The young pitcher immediately set the tone with a 102.4 mph fastball on his very first pitch of the evening. Remarkably, that opening heater proved to be the slowest pitch he threw during the entire first inning.


Throughout the contest, Misiorowski demonstrated why he is considered the hardest-throwing pitcher in Major League Baseball. He unleashed 41 pitches clocked at 100 mph or faster, with 10 of those high-velocity strikes coming in a dominant first inning against the heart of the Yankees' batting order.


Redefining the Standards for Starting Pitchers

According to data provided by Sarah Langs of MLB.com, the previous record for the fastest pitch thrown by a starter in the Statcast era (dating back to 2008) belonged to Jordan Hicks, who hit 103.2 mph on July 12, 2022. During his outing on Friday, Misiorowski surpassed that mark on seven separate occasions.


His statistical output was just as impressive as his radar gun readings:

  • Innings pitched: 6 scoreless
  • Strikeouts: 11
  • Hits allowed: 2
  • Walks: 2

The Brewers secured a commanding 6-0 win, with reliever Shane Drohan closing out the final three innings to maintain the shutout. For historical context, the absolute fastest pitch tracked by MLB remains the 105.8 mph fastball thrown by Aroldis Chapman in 2010.


An Unforgettable Welcome for a Rookie

The intensity of Misiorowski's delivery was most apparent during the second inning against Yankees prospect Spencer Jones, who was making his MLB debut. In Jones' first major league at-bat, he faced a barrage of heat:

«103.6 mph up and in for a called strike, 102.3 mph up and in for a swinging strike, 103.6 mph up and in fouled off, 89 mph curveball in the zone for a foul-tip strikeout.»

While the encounter served as a brutal introduction to the big leagues, Jones managed to recover later in the game, eventually drawing a walk in the fifth inning.


A Breakout Season

While Misiorowski has long been touted for his raw velocity, Friday marked a new peak in his professional career. Throughout the 2026 season, he has established himself as one of the most intimidating pitchers in the league. As of Friday, he leads all qualified MLB starting pitchers with a 39.5% strikeout rate, complemented by an impressive 2.43 ERA and a 0.95 WHIP.
