Jacob Misiorowski fired the fastest pitch on record at 103.7 mph during the Milwaukee Brewers’ 7-1 win over the Colorado Rockies, outpacing every pitch tracked since at least 2008—then backed it up with a seven-inning effort that included eight strikeouts.
Milwaukee’s stadium didn’t just buzz during the seventh—on Saturday, it was the third inning that caught everyone’s attention.
Brewers right-hander Jacob Misiorowski threw what MLB is calling the fastest pitch on record in a 7-1 win over the Colorado Rockies. ripping a 103.7 mph fastball from the radar gun during an at-bat for Rockies third baseman Kyle Karros. The league says no one has thrown a pitch harder since at least 2008, when full pitch tracking began.
That night wasn’t a one-off blast. Misiorowski logged 52 pitches that reached triple digits. And while the highlight belonged to speed. the record pitch also landed far from the strike zone—it was well out of the zone and counted as a ball against Karros. according to the account of how it played out.
Brewers manager Pat Murphy was asked about the significance of the velocity. He didn’t treat it like a magic trick on its own.
“Miz has got great extension and great velocity, so that doesn’t surprise me,” Murphy told reporters. “But we’ve got to get off that — the harder the better, and all that. He’s got to throw the ball in the zone and throw his other pitches in the zone. As I say often, good hitters can time up anything.”.
Murphy’s emphasis landed on the same tension created by the record itself: hard can impress, but it still has to do work.
It did, across Misiorowski’s full outing. The 2025 All-Star went seven innings, allowing one run on four hits and striking out eight. The fastball that made headlines didn’t define the night by itself. even as MLB’s X account added a tongue-in-cheek nod to the wrestling world—referencing WWE rivalry between Danhausen and The Miz—in the course of spotlighting Misiorowski’s dominance on the mound.

103.7 is insane… dude threw a missile lol
I don’t even watch baseball like that but 103.7 mph??? Sounds fake. Also why was it out of the zone if it’s “fastest on record” like what’s the point.
So he throws the fastest pitch but it was a ball… that’s kinda wild. I guess the radar gun just said “fast” and everyone clapped? Still he pitched 7 innings right, so maybe it worked anyway. Rockies always get cooked like that.
Brewers out here throwing like the WWE thing? They keep mixing sports with wrestling now, next thing you know the pitcher is gonna take a chair to the mound. But seriously I thought records had to be strikes?? The article said it was way out of the zone yet it was the fastest since 2008, so like… did they just measure the speed only? Either way 7-1 is a beatdown.
