Chicago Cubs · Pitcher
After a rough 2025 debut marked by a 7.02 ERA and 1.77 WHIP, Rolison has made a significant stride early in 2026 with a 1.99 ERA and 1.11 WHIP across 31.2 innings, showcasing improved command and control. His 5-1 record with 31 strikeouts positions him as a viable depth starter in mixed leagues, offering potential wins and solid ERA/WHIP production if the early-season success holds. The key fantasy concern remains durability and consistency—his 2025 struggles suggest he may still be adjusting to MLB hitters, so he carries some bust risk despite the hot start. If Rolison maintains his 2026 trajectory as a reliable mid-rotation arm, he could provide value in wins and strikeouts for managers seeking pitching depth on the waiver wire.
