Overview
- Misiorowski finished the 2026 regular season with a 100.6 mph average four‑seam fastball, threw 1,115 pitches at 100 mph or higher, and recorded a 105.5 mph pitch on June 26 that is the fastest tracked from a starting pitcher.
- He extends extreme speed across his whole arsenal, posting the fastest cutter, one of the fastest sliders, a 92.5 mph changeup near the top among starters, and an 88.0 mph curveball that led starters.
- The Brewers started Misiorowski in Game 1 of the NLCS on Sunday, and he worked into the fifth inning while throwing a high share of 100‑mph offerings, including 44 pitches at or above triple digits in that start.
- Biomechanics experts point to Misiorowski’s long limbs, hip‑shoulder separation and center‑of‑mass speed as reasons for his velocity, but also warn that roughly 105 mph approaches the practical limit for ulnar collateral ligament stress.
- His workload and dominance make him the clear NL Cy Young front‑runner and create a high‑stakes management problem for the Brewers, with potential consequences for his health, the rotation’s depth and how teams use ultra‑high‑velocity starters going forward.
