Week 21 of 2025 brings a compact set of starting-pitcher waiver options, tailored for shallow leagues but with deeper-leaning plays that could pay off in standard formats. Will Warren anchors the top tier, offering reliable volume and recent five-inning quality starts as the Yankees chase wins. Jose Quintana stabilizes the rotation with dependable innings and solid ratios on a strong Brewers squad. Jose Soriano combines strikeouts with groundball variety for a back-end slot in many leagues. Hurston Waldrep offers upside as a top Braves prospect getting a late-season shot, while Charlie Morton provides veteran savvy as Detroit managers lean on experience. In deeper formats, Cristian Javier returns to form with injury-recovery potential; Zebby Matthews brings swing-and-mmiss upside tempered by HR risk; Nolan McLean, Jason Alexander, and Ryan Bergert each offer speculative, weekend-ready options with varying ceilings. Kyle Bradish, Michael McGreevy, Sean Burke, Michael Lorenzen, and Joey Wentz close the list with a mix of floor, wins potential, and breakout vibes. Proactive rosters can maximize Week 21 by pairing safe floors with high-upside stashes, while tracking BvP and PvB data for favorable matchups.
