Brewers’ Jacob Misiorowski Exits With Cramping But Allows No Hits Before Injury

Milwaukee Brewers pitcher Jacob Misiorowski insisted he didn’t realize he had a no-hitter going when he took the mound for the sixth inning of his major league debut.

“I had no clue,” the 23-year-old flamethrower said after Milwaukee’s 6-0 victory over the St. Louis Cardinals on Thursday night. “I thought one of the popups landed.”

It appears that the injury that knocked the 6-foot-7 right-hander out of the game wasn’t serious.

Misiorowski had just thrown a third straight ball to Victor Scott to open the sixth when his right foot landed awkwardly on the front of the mound. After the Brewers’ medical staff went out to check on him, Misiorowski exited the game and Nick Mears came out of the bullpen.

The Brewers later said Misiorowski left due to cramping in his right calf and quadriceps.

“Of course, I don’t want to leave like that,” Misiorowski said. “I feel like I could have kept going, but I cramped up. Stuff happens.”

Until Misiorowski’s untimely exit, his debut couldn’t have gone much better as he showcased the elite velocity that made him one of baseball’s top pitching prospects.

“I don’t think it was anywhere near what I thought,” he said. “I thought I was going to give up a few hits, get your ‘welcome to the show’ kind of experience. I just kind of rolled with it.”

Control has always been the concern as Misiorowski worked his way up the ladder in the Brewers’ farm system. He did have four walks on Thursday’s outing, but he also struck out five batters while lighting up the radar gun all night.

He reached 100 mph with each of his first three pitches he threw to Lars Nootbaar to start the game. Two pitches later, Nootbaar fouled off a 102.2 mph offering. According to MLB.com, that 102.2 pitch was the fastest by any Brewers starter since pitch tracking began in 2008.

Statcast indicated 14 of the 81 pitches Misiorowski threw – including 11 of his first 24 – reached at least 100 mph. According to MLB.com, the only pitchers since 2008 to throw more pitches of at least 100 mph in their debuts were Erik Cordier in 2014, Hunter Greene in 2022, Mason Miller in 2023 and Paul Skenes in 2024.

“We’ve done a good job this year [against] guys we haven’t faced and guys just coming up and making their debuts, just taking a good approach,” Cardinals manager Oliver Marmol said. “But that’s a different arm, man. He did a nice job. The velo is real. The extension is real.”
