Jacob Misiorowski isn't just having a good rookie year. He's rewriting a stat category nobody thought was still up for grabs. According to Codify's numbers, the 24-year-old Brewers righty is allowing 4.78 hits per 9 innings this season, the lowest single-season rate in MLB history for any pitcher with 100-plus innings. The next name on that list is Ferdie Schupp from 1916. That's the company we're talking about.
It gets weirder. On top of the hits-allowed record, Codify also flagged Misiorowski as the first pitcher in MLB history to string together an 18-start streak of at least 6 strikeouts while allowing fewer than 6 hits in every one of those outings. That's not a hot week. That's basically half a season of a guy being nearly untouchable and racking up strikeouts on a nightly basis.
Jacob Misiorowski is the first pitcher in MLB history to have a streak of 18 starts striking out at least 6 batters while allowing fewer than 6 hits.
The stuff behind it is exactly what you'd expect from a 6-foot-7 flamethrower who's been touching triple digits all year. Misiorowski leads MLB in strikeouts, and separate reporting has him sitting on a sub-2.00 ERA and an MLB-best WHIP through 20-plus starts, numbers that put him firmly in the AL/NL Rookie of the Year and Cy Young conversation depending how you slice it. He's a second-round pick from 2022 who signed for $2.35 million out of Crowder College and didn't even debut in the majors until June of 2025. Now, a little over a year later, he's the guy analytics accounts are building historical comp charts for.
The strikeout stuff you can see for yourself. Rob Friedman's been posting Misiorowski clips all year because the pitch design is that filthy — a fastball that plays up in the zone, a slider and cutter he's been refining, and the kind of swing-and-miss shape that gets him through lineups on pure stuff alone.

None of this happens without the velocity. Misiorowski has been sitting in the upper-90s and dipping into the 100-102 mph range on a start-to-start basis, per Codify's pitch tracking, which is a big reason hitters simply aren't squaring him up. When a guy is missing bats at a 40-plus percent clip AND limiting the ones who do make contact to weak hits, you get a hits-per-9 number that looks like it's from the dead-ball era, not 2026.
The bigger question now is workload. Misiorowski is already closing in on last year's innings total, and the Brewers have shown they're willing to pull him early even mid-no-hit-bid to protect him for the stretch run. If Milwaukee is playing October baseball, how much they lean on their rookie phenom down the stretch is going to be one of the sport's more interesting subplots.
