MILWAUKEE -- Brewers starter Jacob Misiorowski threw a first-inning fastball Friday to Cubs center fielder Pete Crow-Armstrong that was clocked at 105.5 mph, breaking his own record for the fastest pitch recorded by a starting pitcher in the pitch tracking era (since 2008).
It's also tied for the third-fastest pitch by any hurler, behind two from longtime reliever Aroldis Chapman (105.8 in 2010, 105.7 in 2016) and matching Ben Joyce (105.5 in 2024).
"It's cool," Misiorowski said after the Brewers' 6-2 win. "I think I slipped a little bit on that pitch. My front foot slid out from under me."
Misiorowski, 24, hit 103.1 mph on his first pitch of the game, followed by a 104.3 mph fastball before reaching 105.5 mph on the next pitch. Crow-Armstrong actually fouled that one off before striking out three pitches later.
Misiorowski went six innings, giving up a solo home run to Cubs designated hitter Seiya Suzuki -- his first allowed in 75â…“ innings. The Cubs battled him well, walking four times while driving up his pitch count. The right-hander threw a season-high 107 pitches, with his final pitch of the night -- a 102.8 mph fastball -- striking out Cubs left-fielder Ian Happ with the bases loaded.
"They had a game plan coming in to battle me and foul s--- off," Misiorowski said. "They stuck with it. More power to them."
A few moments later, Brewers center fielder Garrett Mitchell erased a 1-0 deficit with a two-run homer in the bottom of the sixth. The Brewers never relinquished the lead, scoring all six of their runs from the sixth inning on.
Asked about Misiorowski's first-inning velocity, Mitchell was nearly speechless.
"I have nothing else to say about it," Mitchell said with a smile. "It's impressive. It feels like every time he goes out there, he's breaking a record of some sort."
The 105.5 mph first-inning fastball broke Misiorowski's own record for a starting pitcher achieved June 12, when he threw 104.5 mph to Philadelphia Phillies designated hitter Kyle Schwarber.
"Where does it stop?" Brewers manager Pat Murphy said with a smirk. "I think there's a limit there."
In Misiorowski's estimation, he hasn't quite hit that limit. He was asked if 106 mph is possible.
"I definitely think it's possible," he said. "Science says you can hit 108. Someone eventually is going to hit it. If that's me, cool. I don't think that's something I need to focus on. Speed is cool, but if it doesn't win a ball game, it doesn't matter."
Misiorowski's ERA is 1.45, third lowest by a pitcher through his first 16 starts of a season over the past 50 years, behind only Trevor Rogers (1.43) last season and Nolan Ryan (1.29) in 1981. Misiorowski struck out eight Cubs on Friday while matching a season high with the four walks.
"I sprayed a little bit," Misiorowski said. "There's always something to work on between starts."
