Overview
- Jacob Misiorowski’s first pitch of Game 1 was clocked at 103.5 mph by MLB’s Statcast on Friday, the fastest single pitch recorded in World Series history.
- The stadium video board listed the pitch at 103.4 mph while Statcast showed 103.5 mph, highlighting small but important differences between public displays and MLB’s official tracking system.
- This season Misiorowski produced unprecedented velocity volume with 1,115 pitches at 100 mph or higher and a top speed of 105.5 mph in June, numbers that dwarf previous single-season totals.
- His brief 2026 postseason work — failing to pass the fifth inning in two earlier starts and throwing very high pitch counts in the NLDS and NLCS — increases pressure on the Brewers to limit his innings.
- Statcast-era comparisons place Misiorowski alongside elite flamethrowers such as Aroldis Chapman and Jordan Hicks, and the next key developments will be how the Brewers deploy him and protect his long-term durability.
