Jacob Misiorowski raised his own pitching ceiling on Friday, June 26, recording a personal-best 105.5 mph. The Milwaukee Brewers ace not only shattered his earlier mark of 104.5 mph this month, but also tied a modern speed milestone by matching the third-faste
Friday night started with a spark that felt almost impossible to ignore: Jacob Misiorowski, Milwaukee’s ace, uncorked a personal-best fastball clocked at 105.5 mph on June 26, after already setting a high-water mark earlier this month.
The pitch didn’t just register. It rewrote his own bar. Misiorowski had previously posted his fastest pitch earlier this month against the Philadelphia Phillies at 104.5 mph. On Friday, he pushed past that with a 105.5 mph offering, turning a good start into a headline-worthy moment.
It happened in the first inning against the Chicago Cubs. Misiorowski’s fastball to leadoff batter Pete Crow-Armstrong was tracked at 105.5 mph and even after Crow-Armstrong fouled the pitch off. the number stayed fixed—tying Los Angeles Angels reliever Ben Joyce for the third-fastest pitch in the 18-year pitch-tracking era.
Joyce’s mark came on September 3, 2024. Misiorowski’s came on June 26, and the overlap is what makes the moment feel bigger than one game: elite velocity isn’t just back—it’s crowded.
Aroldis Chapman still holds the top two spots in the pitch-tracking era. His 105.8 mph pitch was recorded on September 24. 2010. with the Cincinnati Reds. and his 105.7 mph mark came on July 18. 2016. with the New York Yankees. Chapman also owns the record set in September 2010 with the Cincinnati Reds.
The full list of fastest pitches in the pitch-tracking era (2008) underscores how tightly grouped this new tier of speed is:
1. Aroldis Chapman, Reds, Sep. 24, 2010 — 105.8 mph
2. Aroldis Chapman, Yankees, July 18, 2016 — 105.7 mph
T3. Jacob Misiorowski, Brewers, June 26, 2026 — 105.5 mph
T3. Ben Joyce, Angels, Sept. 3, 2024 — 105.5 mph
5. Aroldis Chapman, Yankees, July 18, 2016 — 105.4 mpg
6. Aroldis Chapman, Yankees, July 22, 2016 — 105.2 mph
T7. Aroldis Chapman, Pirates, Aug. 7, 2024 — 105.1 mph
T7. Aroldis Chapman, Cubs, Aug. 2, 2016 — 105.1 mph
T7. Aroldis Chapman, Yankees, July 22, 2016 — 105.1 mph
T7. Aroldis Chapman, Yankees, July 18, 2016 — 105.1 mph
T11. Jordan Hicks, Cardinals, May 20, 2018 — 105 mph
T11. Aroldis Chapman, Yankees, July 23, 2016 — 105 mph.
What’s changed for Brewers fans is how close they now are to the very top. Misiorowski has already shown he can reach 105.5 mph on demand, and he did it by first building a record at 104.5 mph earlier this month—then clearing it less than a month later.
The Brewers ace’s sprint toward the league’s speed summit raises the immediate question that always comes with numbers like these: if catching up has gotten harder, is the all-star-game chatter finally catching up to reality—or is it about to get louder?

105.5?? that’s like throwing a brick at people lol.
So he tied Ben Joyce? I swear I heard this earlier but with a different date. Pitch tracking era sounds made up like it’s not even real.
105.5 in the first inning and it stayed at the same number even after a foul… so the radar guy just said “yup same” 😂 Also Phillies game earlier this month? Brewers always got guys peaking randomly.
Brewers ace topping his mark and all I’m thinking is Aroldis Chapman still owns the “real” speed. Like if Chapman was on the mound he’d be 110. But then again tracking started in 2008 so maybe everyone before that was just slower for no reason.
