# Brewers' Misiorowski Uncorks a 105.5 MPH Pitch, Among the Fastest Ever Recorded

Milwaukee Brewers rookie Jacob Misiorowski fired a fastball clocked at 105.5 mph in a win over the Chicago Cubs, a pitch that Statcast data ranks among the fastest ever thrown since baseball began tracking velocity.

Some pitchers chase 100 mph for a career. Jacob Misiorowski blew past it. The Milwaukee Brewers' rookie right-hander unleashed a fastball measured at 105.5 mph on Friday, a pitch that placed him among the small handful of arms ever to reach that velocity, as the Brewers beat the Chicago Cubs 6-2.

## A pitch that turned heads

The heater came in the third inning, and even Misiorowski seemed to treat the radar reading as a happy accident. "It's cool," he said afterward, [according to ESPN](https://www.espn.com/mlb/story/_/id/49194044/jacob-misiorowski-throws-heater-clocked-1055-mph-vs-cubs). "I think I slipped a little bit on that pitch." The batter, Pete Crow-Armstrong, fouled it off and struck out three pitches later.

ESPN, citing Statcast, reported that the 105.5 mph reading ranks among the fastest pitches in the tracking era, trailing only a pair of triple-digit deliveries from Aroldis Chapman and matching a 2024 pitch by Ben Joyce. Independent confirmation of the precise ranking was limited at publication, so the exact place on that leaderboard is best treated with some caution. What is not in doubt is the company it keeps: for context, the average major-league fastball sits around 94 mph.

## More than a single radar reading

The velocity could overshadow what was a dominant outing. Misiorowski worked six innings, struck out eight, walked four and allowed a lone home run, ESPN reported, closing his night by punching out Ian Happ with another pitch above 102 mph. The performance lowered a season earned-run average that ESPN described as one of the best marks through a pitcher's first 16 starts in the past half-century.

## Chasing the limit

For his part, the 24-year-old sounded more curious about the ceiling than satisfied with the number. "Science says you can hit 108," Misiorowski said, per ESPN. "Someone eventually is going to hit it." On Friday, he edged a little closer to whatever that limit turns out to be — and kept the Cubs quiet long enough for Milwaukee to pull away.
