Brewers ace Jacob Misiorowski has been on a torrid run this season, but in particular over the course of his last five starts. In that span, Misiorowski has been nothing short of dominant. He’s pitched 31 1/3 innings in the month of May, surrendering just one earned run while striking out 49 batters and allowing 11 hits and six walks. That’s good for a 0.29 ERA and a 0.54 WHIP while maintaining a K/9 over 14. Over his last six starts, Misiorowski has had eight-plus strikeouts in every single outing and hasn’t surrendered a single extra-base hit in that span. In MLB history, no other pitcher has kept such a streak alive for more than four consecutive starts, per Codify Baseball. In that span, Misiorowski has been nothing short of dominant.

Much of it is due to his ridiculous velocity, and his ability to maintain it even while pitching deep into games. His Monday start against the Cardinals saw him become the first pitcher in the pitch-tracking era to throw 50 pitches at 100-plus mph. Misiorowski had 57 pitches reach triple digits on Monday, and 40 of those clocked in over 101 mph. But what makes Misiorowski so hard for opponents to hit?

Misiorowski had 57 pitches reach triple digits on Monday, and 40 of those clocked in over 101 mph. It’s unprecedented to see a pitcher still reaching triple digits into the fifth, sixth or even seventh inning of games. Misiorowski is a unicorn in that regard, seemingly able to throw as hard in the sixth inning as he is in the first inning. Misiorowski’s first 10 pitches of Monday’s game were clocked at over 101 mph. In the seventh inning, his fastball was still sitting over 100 mph and even touching 102 mph.

Misiorowski continues to defy what baseball fans thought was possible on the mound, and in doing so he’s landed himself in some elite company. He’s the fastest pitcher to 100 strikeouts in a season (11 starts) since Spencer Strider in 2023. He’s also the second pitcher since 1901 to record 100-plus strikeouts while surrendering 50 or less total bases in their first 11 starts, per Opta Stats. The only other pitcher to achieve that was Jacob deGrom in 2021.

He’s defying pitching logic with his combination of velocity and endurance. For fans, it’s game-breaking to watch. For Misiorowski, it’s just another day on the job.
