Milwaukee Brewers pitcher Jacob Misiorowski etched his name into the history books during a remarkable performance against the New York Yankees on Friday night. This outing was not just another game; it was a display of blistering velocity that stunned fans and analysts alike.

Record-Setting Inning

In an extraordinary first inning, Misiorowski recorded the five fastest pitches ever thrown by a starting pitcher, according to the Brewers' official report. His dominating performance included pitches exceeding 103 miles per hour (mph), a feat previously unseen in the major leagues for starting pitchers since tracking began in 2008. Remarkably, only three pitches by other starters had even crossed the 103 mph threshold during regular season and playoffs combined – a record held by Jordan Hicks and Justin Verlander.

Jordan Hicks achieved 103.1 and 103.2 mph on July 12, 2022, while Verlander reached 103.1 mph during Game 5 of the 2011 AL Championship Series. In contrast, Misiorowski surpassed Hicks' previous record by throwing six pitches over that mark in a single inning, demonstrating an unprecedented level of power from the mound.

Striking Out Records

But that wasn’t the only record broken during the first inning. Misiorowski also delivered the two fastest strikeout pitches recorded by a starter in the modern tracking era. He struck out Ben Rice with a blistering 103.3 mph pitch, followed shortly by Trent Grisham, who was caught looking on a 102.8 mph fastball. This double strikeout further solidified Misiorowski’s dominance, as he broke his own record set just months prior. In April, he recorded a 102.7 mph strikeout pitch against Oneil Cruz of the Pittsburgh Pirates.

As a testament to his rising talent, Misiorowski’s previous record was already impressive, surpassing the mark set by Tarik Skubal of the Detroit Lions at 102.6 mph in May 2025. The Brewers now have a new star pitcher who is pushing the boundaries of speed in Major League Baseball.

Continued Dominance

Misiorowski’s prowess didn’t fade as his outing continued. In the second inning, he faced off against Yankees' No. 6 prospect Spencer Jones in his Major League debut. Jones encountered two pitches that clocked in at a jaw-dropping 103.6 mph before striking out. This highlighted Misiorowski’s ability to maintain his astonishing speed throughout the game, a skill that pitchers often struggle to sustain.

Leading into this game, Misiorowski had relied heavily on his four-seam fastball, using it for 61.4% of his pitches, an increase from last season's 55.2%. His results this season had already been eye-catching, as he entered the game with 59 strikeouts while allowing just 23 hits, 15 walks, and 12 earned runs over his first seven starts. This consistent effectiveness solidifies him as a formidable presence on the mound for the Brewers.

The Bigger Picture

What does this mean moving forward for both Misiorowski and the Milwaukee Brewers? For Misiorowski, it’s a mark of his relentless ascent in Major League Baseball. The ability to throw with such speed is rare and invaluable, and if he continues to hone his craft, he could become one of the premier pitchers in the league.

For the Brewers, performances like Misiorowski’s signal hope in their season ambitions. Pitching is a cornerstone of success in baseball, and having a pitcher who can record such high velocities provides not only a tactical advantage but can also spark the rallying spirit of the entire team. The Brewers will undoubtedly look to leverage Misiorowski’s talents as they aim for a playoff berth this season.

Conclusion

Jacob Misiorowski's historic outing against the New York Yankees is a reminder of the extraordinary heights that baseball can reach. As he continues to break records and showcase his talent, he is not just following in the footsteps of past legends but also paving the way for future innovations in pitching. Baseball fans everywhere should keep their eyes on this budding superstar.
