Chicago Cubs | RP
Overall
Summary
Bryce Miller, 27-year-old right-hander for the Seattle Mariners, is being reinstated from the 15-day injured list after straining his left oblique in spring training (retroactive to March 25). Miller made four successful rehab starts between Triple-A Tacoma and High-A Everett, posting a 1.98 ERA with 14 strikeouts and 7 walks over 13.2 innings. His most recent rehab start on May 6 featured five scoreless innings with dominant 98 mph velocity. He is set to make his 2026 season debut on Wednesday, May 13, against the Houston Astros. The Mariners will employ a six-man rotation initially, with potential for a piggyback arrangement with Luis Castillo. Miller struggled in 2025 with a 5.68 ERA and 1.406 WHIP but showed resilience in the postseason with a 2.51 ERA over three starts.
