Scouting Report
Updated May 19, 2026
Luis Castillo is struggling significantly in 2026 with a 6.57 ERA, 1.62 WHIP, and 0-4 record across 8-9 starts. The Seattle Mariners are considering removing him from the rotation due to poor performance, with options including a six-man rotation, bullpen role, or piggyback relief duties. With Bryce Miller returning from injury and Emerson Hancock performing well, Castillo's rotation spot is in jeopardy. He was recently moved to a piggyback reliever role behind Miller on May 18-20, marking a significant role change for the veteran pitcher who has been a model of consistency for the Mariners since 2022.
Strengths
- + Earned a win against the Astros on May 15 with 5 2/3 innings pitched
- + Struck out 6 batters in that start
- + Has experience as a three-time All-Star with a strong track record (3.17-3.64 ERA from 2022-2025)
- + Showed swing-and-miss ability in recent outings
- + Has never pitched in relief at MLB level, providing potential upside if role change works
