Luis Castillo brings frontline stuff, but 2026 command has been inconsistent
Castillo is still a proven, power-righty starter with a long track record of missing bats, but in the 2026 season for Seattle he has been more hittable and less efficient than his peak years, posting a 4.79 ERA with a 1.33 WHIP and 77 strikeouts in 82.2 innings. His best fit is a team that can value veteran poise, competitive mound presence, and upside if his command rebounds; the concern is that he is not currently performing like a shutdown ace, even though the raw arsenal remains attractive.
