Jacob Misiorowski is doing things this season no starting pitcher in history has done before. The Milwaukee Brewers’ 24-year-old right-hander averages 99.8 mph on his 4 seam and topped out at 103.6mph, the fastest pitch ever recorded by a starter in the Statcast era. His 7.5 feet of extension off the mound ranks at the 100th percentile in baseball, and his perceived average velocity of 101.3 mph is the highest ever tracked for a starter.
In May 2026, Misiorowski posted a 0.23 ERA across 38.1 innings with 57 strikeouts, a .101 slugging percentage against (the lowest in any calendar month in MLB history), and became the first pitcher to reach 100 strikeouts on the season. He’s thrown more 100+ mph pitches this year than any starter has thrown in any full season in recorded history.
In this video, I break down the stats, the story, and the science behind the most electric arm in baseball — from a torn-up knee at a junior college in Missouri to rewriting the Statcast record book.
