# Brewers' Misiorowski throws a 105.5 mph pitch, among the fastest ever recorded

Milwaukee Brewers starter Jacob Misiorowski unleashed a 105.5 mph fastball against the Chicago Cubs — tying for the third-fastest pitch in the era of modern tracking, and the hardest ever thrown by a starting pitcher.

It took Jacob Misiorowski three pitches to make history. On Friday night at American Family Field, the Milwaukee Brewers' 24-year-old right-hander threw a fastball that [Statcast clocked at 105.5 mph](https://www.mlb.com/news/jacob-misiorowski-reaches-105-5-mph-against-cubs) to the Chicago Cubs' Pete Crow-Armstrong — tying for the third-fastest pitch ever recorded since the technology began tracking velocity in 2008.

## Where it ranks

Only one pitcher has ever thrown harder in the tracking era: Aroldis Chapman, whose [105.8 mph pitch in 2010](https://sabr.org/gamesproj/game/september-24-2010-reds-aroldis-chapman-tops-105-mph-for-fastest-pitch-ever-recorded/) remains the fastest officially measured, with a 105.7 mph effort to follow. Misiorowski's 105.5 mph equals the mark set by Los Angeles Angels reliever Ben Joyce in 2024, [Sports Illustrated noted](https://www.si.com/mlb/brewers/onsi/brewers-jacob-misiorowski-unleashes-105-5-mph-fastball-3rd-fastest-in-history-pat3).

What sets Misiorowski's pitch apart is the role he plays. Chapman and Joyce are relievers, brought in to throw all-out for an inning or less. Misiorowski is a starter, expected to last six or seven innings — making sustained triple-digit velocity all the more striking. The pitch was the fastest ever thrown by a starting pitcher in the tracking era, surpassing his own previous best of 104.5 mph set roughly two weeks earlier.

## A breakout season

Nicknamed "The Miz," Misiorowski entered the start with a 1.45 earned run average, the best in the major leagues, in his first full season. Against the Cubs he worked six innings, allowing two hits and one earned run — a solo home run by Seiya Suzuki — while striking out eight. The Brewers won 6-2.

His velocity was relentless all night, not just on the record pitch: he averaged 101.6 mph with his four-seam fastball and, with the bases loaded in the sixth, struck out Ian Happ on a 102.8 mph heater. Afterward, Misiorowski suggested there may be more in the tank. "I think I slipped a little bit on that pitch," he said. "I think I've got a little more."

## The velocity arms race

Misiorowski's outing sits at the leading edge of a long trend. Average fastball speeds across Major League Baseball have risen steadily over the past 15 years, pushed up by specialized training, biomechanical coaching and a focus on raw arm strength. Relievers first nudged the ceiling toward 105 mph; a starter now operating in that range, and holding triple digits deep into a game, points to a new frontier. With Chapman's record sitting just three-tenths of a mile per hour above Friday's pitch, baseball's true speed limit may not yet have been found.
