Jacob Misiorowski Injury Update: Brewers Ace Removed From No-Hitter

Jacob Misiorowski’s latest MLB start brought all the drama you’d hope for. The 24-year-old righty flirted with a no-hitter at Nationals Park, but a right hamstring cramp cut his night short. Milwaukee still rolled to a 6-1 win over Washington, giving his breakout season another boost and stirring up more talk about his durability and ceiling as a rotation anchor.

Misiorowski’s near-no-hitter and dominant outing

The Brewers’ young ace punched out eight over 5⅓ innings. He turned a routine midweek start into a showcase of power and precision.

He retired four straight hitters in a row, and for a moment, it felt like he might be on the verge of something historic. Then the hamstring cramp hit, and with his pitch count at 85, he signaled for a trainer and left the game with the no-hitter still alive through the sixth.

Pat Murphy called it a minor issue and said the team wouldn’t risk pushing him, hoping to avoid another cramp. Misiorowski led MLB in strikeouts (59 in 38 innings), strikeout percentage (37.2%), and whiff percentage (39.5%) at the time—numbers that really highlight just how electric he’s been this season.

Aaron Ashby came on to finish the sixth, and the no-hit bid finally ended in the seventh when Daylen Lile ripped a double off the wall. Misiorowski threw 85 pitches, 54 of them at least 98 mph, and even mixed in a 98.4 mph slider for good measure.

His ERA dropped to 2.84 and his WHIP to 1.00. Brewers fans can only hope the hamstring issue is just a minor hiccup in what’s shaping up to be a special career.

Misiorowski’s journey already feels a bit wild. He missed time last August with a left tibia contusion, and in his MLB debut, he had to leave—no-hitter intact—because of an ankle injury. It’s a pattern that makes you wonder about his resilience, but also makes every outing feel like appointment viewing.

Velocity, strikeouts and the tempo of the heat

Misiorowski’s fastball looked like a weapon all night. He fired 43 pitches in the 100-to-103 mph range.

His first-inning average velocity hit 101.9 mph, which the Milwaukee Journal-Sentinel said was the highest single-inning average by a starter in the Statcast era. That kind of velocity, paired with a slider touching 98.4 mph, gives him a rare mix—he can make hitters miss and just flat-out overpower them early in counts.

Even with the cramp, the numbers tell the story. When he sits in the upper reaches of the velocity scale, he can dominate. He came into this start with a sky-high strikeout rate and whiff percentage, and you could see why, watching him attack the zone with late life on his heater and a nasty, sharp slider.

Injury update and manager’s cautious approach

Manager Pat Murphy said the hamstring issue looked minor, and the Brewers played it safe. They didn’t want to risk tests or moves that might trigger another cramp.

That’s just how the Brewers operate—they’d rather protect a young arm than gamble on a single outing. Trainer Brad Epstein checked him out as a precaution, and the hope is it’s nothing that a little rest can’t fix.

Past injuries and a look at Misiorowski’s resilience

Misiorowski’s resilience has already been tested, both in the minors and in his big-league debut. He missed time with a tibia contusion last August, and in his MLB debut, he got pulled with a no-hitter still going after an ankle injury.

Those moments have shaped the story around him. This latest near-no-hitter feels less like a setback and more like another chapter in a career that’s already seen its share of twists.

What it means for Brewers and Misiorowski’s future

From Milwaukee’s perspective, the night just made them more confident in his upside. They’re seeing their long-term rebuild plan get some validation, which has to feel good.

He’s got that elite velocity, keeps racking up strikeouts, and isn’t afraid to attack hitters in the zone. That’s a big deal for their future, as long as his health holds up.

The Brewers will watch his hamstring closely. They’re trying to balance his workload so he can stay sharp for a playoff push—and maybe more.

• ERA: 2.84
• WHIP: 1.00
• Strikeouts: 59 in 38 innings
• Strikeout rate: 37.2%
• Whiff rate: 39.5%
• Fastball velocity: 101.9 mph average in the first inning
• Programmed workload: 85 pitches; 54 at least 98 mph

Misiorowski’s pace every night and the sheer power of his fastball and slider stand out. If he can stay healthy, you have to wonder—could he anchor Milwaukee’s rotation for years?
