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.

Misiorowski has thrown the 12 fastest pitches by a starter. His previous high was 103.4 mph against St. Louis 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.

Misiorowski threw a record 57 pitches 100 mph or faster in the May 25 game, including 40 of 101 mph or more.
