Scouting Report

Updated May 20, 2026

Jacob Misiorowski, 24-year-old Milwaukee Brewers right-hander, is experiencing a breakout 2026 season with elite strikeout production (13.97-14.0 K/9, leading the NL) and a 2.84 ERA through his first 8 starts. He recently threw historic fastballs against the Yankees, setting records for fastest pitches by a starting pitcher (10 pitches at 103+ mph). However, he suffered a hamstring cramp in a start against Washington and was pulled early from a subsequent start against San Diego as a precaution. The Brewers are managing his workload carefully due to his young age and previous heavy innings load in 2025 (66 MLB innings plus minor league work). Despite the injury concerns, he's listed as probable starter and is considered a must-start in fantasy leagues with Cy Young odds improving significantly.

Strengths

  • + Elite strikeout rate leading NL (13.97-14.0 K/9)
  • + Historic fastball velocity - 10 pitches at 103+ mph in single game

  • + Brewers confident in his recovery from hamstring cramp
  • + Manager and player both smiling during injury precaution, suggesting minor concern
