Jacob Misiorowski's 1st-inning fastball velocity for Brewers vs. Yankees is unmatched in baseball history originally appeared on The Sporting News. Add The Sporting News as a Preferred Source by clicking here.
Jacob Misiorowski may have been just a little amped up to face the New York Yankees.
The Milwaukee Brewers' right-handed ace threw the most absurd first inning of fastball velocity in baseball history.
To sum it up one way: His 10th-fastest pitch of the first inning was 102 miles per hour.
He touched 104 once — technically 103.6 MPH rounded up, which he threw to Aaron Judge.
He hit 103 eight times.
And then he had that 102.
Absolute absurdity.
Misiorowski hit 103.6 miles per hour twice more in the second inning, too. All of these went down as the fastest pitches ever recorded by a starting pitcher, according to Sportsnet.

Misiorowski is consistently one of the hardest-throwing pitchers in the game, despite starters usually throwing softer than relievers.
His slider, for example, often reaches the upper-90s.
And in this case, his heater was fully ablaze in the first inning against the Yanks.
You aren't gonna see anything like this very often, unless it's Misiorowski again.
And for those wondering: He isn't the fastest thrower this season out of all pitchers. That honor belongs to the Padres' incredible closer, Mason Miller.
Fastest pitches in MLB history
This seems like a worthy list to break out in honor of Misiorowski's big inning.
The fastest pitch thrown recently came in September 2024 from Angels reliever Ben Joyce — it was measured at 105.5 miles per hour.
Aroldis Chapman, though, has the two fastest pitches of the Statcast era — 105.8 miles per hour in 2010, and 105.7 miles per hour in 2016.
Chapman holds the next six spots past that Joyce pitch, too.
Jordan Hicks has hit 105 miles per hour twice, as well, both in 2018.
The aforementioned Padres closer, Mason Miller, hit 104.5 miles per hour in the 2025 playoffs, a postseason record.
