Gavin Williams leads the MLB postseason strikeout market at 78.5% implied probability due to his 33 strikeouts through the ALDS and ALCS, including games with 12 and 11 Ks, across 16.2 innings for Cleveland. This volume and rate separate him from Drew Rasmussen at 19.1%, who has 27 strikeouts for Tampa Bay amid the ongoing World Series. Other active arms like Jacob Misiorowski sit far lower at 2.9% after limited playoff work. Trader consensus reflects Williams' recent form, deeper run, and confirmed starts that have extended his edge, while the crowded field of remaining pitchers faces shorter remaining series and lower per-game ceilings. Postseason totals reset separately from regular-season marks.
