Luis Castillo Finds His Groove with Dominant Stretch Ahead of Washington Matchup

Luis Castillo is locked in, boasting a stellar 1.27 ERA and 0.77 WHIP over his last 14.2 innings. Despite earlier frustration with Seattle's piggyback pitching strategy, the veteran right-hander remains a key cog for the first-place Mariners, who lead the division with a 34-32 record. He continues to deliver high-quality frames even as the team manages injuries to key players like catcher Cal Raleigh.

While Castillo's overall 2026 stats show a bloated 5.35 ERA and 1.39 WHIP, his recent surge is a clear indicator of regression toward his career norms. Our models project him to stabilize with a 3.76 ERA and 1.19 WHIP over 177.0 projected innings this season. His 30 strikeouts over his last 25.5 innings demonstrate that his swing-and-miss stuff has fully returned, making his early-season struggles a thing of the past.

Castillo is scheduled for a single start this week on June 13th on the road against the Nationals. He matches up against Cade Cavalli, who enters the contest with a beatable 3.88 ERA and a high 1.44 WHIP. Armed with excellent recent form and a highly favorable matchup, Castillo should be locked into all lineups. Verdict: Start.
