2026 Fantasy Outlook
No full-time reliever threw more innings than Leahy and his 88 frames in 2025. He began the season pitching earlier in games for Cardinals manager Oliver Marmol but quickly earned his skipper's trust in leveraged appearances. Leahy made his first and only start on the final day of the regular season, tossing three scoreless innings, and it was a preview of what's to come as the Cards stretch him out as a rotation option in 2026. The 28-year-old hasn't been a full-time starter since 2022 at Double-A Springfield, where he had a 5.23 ERA and 11.1 percent walk rate. Leahy's control has gotten much better since then (7.6 percent walk rate in the majors) and he throws six pitches, so it's not far-fetched to think he can handle the transition. He still has to win a rotation spot, but if he does, a rebuilding St. Louis club could give him some leash to see how it works out. Read Past Outlooks

PSt. Louis Cardinals
June 17, 2026
Leahy (5-4) took the loss against the Padres on Wednesday, allowing three runs on seven hits and one walk with seven strikeouts over six innings.
Analysis
Leahy allowed a run in three separate innings but pitched well overall, throwing 57 of 81 pitches for strikes while generating an impressive 11 whiffs. It also matched a season-high workload for the 29-year-old, who tossed six frames in his only other quality start May 16. He owns a 4.63 ERA, 1.57 WHIP and 59:26 K:BB across 70 innings this season and lines up for a home matchup against the Diamondbacks next week.

Latest Fantasy Rumors
Should get rotation chance
PSt. Louis Cardinals
October 14, 2025
The Cardinals plan to have Leahy stretch out during the offseason and compete for a rotation spot in 2026, reports Katie Woo of The Athletic.
Analysis
The right-hander started a bullpen game in the season finale to given him some experience prepping as a starting pitcher, and St. Louis will have continue him on that path this winter. Leahy pitched well out of the bullpen in 2025, recording one save and 18 holds in 62 outings with a 3.07 ERA, 1.23 WHIP and 80:28 K:BB across 88 innings. The 29-year-old hasn't worked regularly as a starter since 2022 with Double-A Springfield, so he may not have a smooth transition back to the rotation.
