Quinn Mathews Quickly Emerging as Priority Stash Target?
St. Louis Cardinals left-handed pitching prospect Quinn Mathews has begun to turn the corner at Triple-A and is quickly emerging as a top prospect to stash among pitchers. Mathews turned in a dominant debut season in the St. Louis system in 2024 but has yet to return to that level of play. In 2025, he logged only 99 innings and saw those troubles linger early in 2026. Through his first 35 2/3 innings this season, the southpaw posted a hefty 5.55 ERA with a 1.63 WHIP. During this stint, Mathews posted a rough 44:30 K:BB. However, over his last 21 innings of work (four starts), the former Stanford standout has held a stellar 1.71 ERA with a much-improved 28:9 K:BB. While he may need to show this success over a longer stretch, he has a clear path to the majors given St. Louis' weak rotation. He is a viable target in the 12+ team leagues ahead of Week 13, but can quickly enter priority stash range if he turns in a strong conclusion to June.
