DENVER -- Milwaukee Brewers ace Jacob Misiorowski threw a 103.7 mph pitch Saturday night against the Colorado Rockies, the fastest by a starter since tracking began in 2008.
The 24-year-old right-hander's record-setting pitch was low and outside to Kyle Karros in the third inning.
"It's one of those things: It is what it is," Misiorowski said. "I'm going to keep going, trying to get strikeouts, and if that's what it takes to get strikeouts, then so be it."
Misiorowski has thrown the 12 fastest pitches by a starter this season. His previous high was 103.4 mph against the St. Louis Cardinals on May 25.
He threw 52 pitches 100 mph or faster Saturday night, including a record 45 of at least 101 mph. He allowed just an unearned run while striking out eight in seven innings, lowering his ERA to 1.50 in a 7-1 victory over the Rockies at Coors Field.
"Miz has got great extension and great velocity, so that doesn't surprise me," Brewers manager Pat Murphy said about the 103.7 mph fastball. "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."
Misiorowski threw a record 57 pitches 100 mph or faster in the May 25 game, including 40 of 101 mph or faster.
Aroldis Chapman holds the record for fastest pitch by any pitcher since 2008, throwing a 105.8 mph pitch as a member of the Cincinnati Reds in 2010.
Misiorowski moved his career strikeout total to 203 in 28 appearances, tying him with the Pirates' Paul Skenes and former Mets right-hander Noah Syndergaard as the seventh-fastest player in MLB history to reach 200 strikeouts.
