Milwaukee Brewers starter Jacob Misiorowski set a new benchmark for starting pitchers on Saturday night, firing a 103.7 mph fastball against the Colorado Rockies that ranks as the fastest by any starter since velocity tracking began in 2008. The 24-year-old right-hander delivered the heater low and away to Kyle Karros in the third inning, part of an electric 52-pitch barrage at triple-digit velocity.

Misiorowski's blazing performance powered Milwaukee to a convincing 7-1 victory at Coors Field, where he struck out eight batters over seven innings while allowing just an unearned run. His ERA now sits at a pristine 1.50 through the season, demonstrating that raw velocity translates to results. The young ace established another record by throwing 45 pitches at 101 mph or harder, building on his previous high of 103.4 mph from May 25.

Brewers manager Pat Murphy praised Misiorowski's natural ability but emphasized the need for better command. 'Good hitters can time up anything,' Murphy noted, suggesting that simply overpowering batters isn't enough for sustained success. The organization recognizes they have something special in their rotation.

Historically, only Aroldis Chapman has thrown harder, reaching 105.8 mph in 2010. Misiorowski also joined elite company by reaching 203 career strikeouts in just 28 appearances, tying him with Paul Skenes and Noah Syndergaard as the seventh-fastest to reach 200 strikeouts in MLB history.
