Tagged with loss Thursday Castillo (0-1) was tagged with the loss Thursday against the Padres, allowing four runs (one earned) on seven hits and three walks across 5.1 innings. He struck out three.

Impact Castillo came up just two outs away from notching a quality start, but the struggles the veteran has endured can't be overlooked right now. After opening the season with six scoreless innings and seven Ks in a no-decision against the Yankees in his season debut March 30, Castillo has given up 15 runs (11 earned) on 23 hits and a 10:5 K:BB across 12.1 frames in his three starts in April. He's scheduled to make his next start next week at home against the A's.

Ineffective again Sunday Castillo allowed seven runs on 10 hits and one walk while striking out three batters over 3.1 innings in a no-decision against Houston on Saturday.

Impact The Mariners gave Castillo a two-run lead in the first inning, but the veteran hurler fell behind when Taylor Trammell cleared the bases with a three-run double in the second. Castillo gave up three more runs in the third and another in the fourth before being pulled with one out in the latter frame. After tossing six scoreless innings against the Yankees in his first start of the campaign, Castillo has surrendered 11 runs (10 earned) over seven frames across his past two starts. He'll try to get back on track in his next start, which lines up to be a road outing in San Diego.

Struggles in no-decision Castillo did not factor into the decision Sunday against the Angels, allowing four runs (three earned) on six hits and one walk while striking out four over 3.2 innings.

Impact Castillo couldn't find a rhythm in this one, allowing at least two baserunners in every inning he worked and exiting before completing four frames for the first time since 2024. The right-hander ran into trouble immediately, allowing a leadoff double to Zach Neto before Jorge Soler brought him home with an RBI single, and the outing didn't improve much from there. Unlike his dominant Opening Day outing in which he tossed six scoreless innings with seven strikeouts, Castillo failed to fool hitters Sunday and was consistently pitching under pressure. The 33-year-old will look to bounce back in his next scheduled start against Houston, though it presents a tough test against one of the league's most productive offenses early in 2026.

Dominates Yankees, reaches 1500 Ks Castillo did not factor into the decision Monday against the Yankees, allowing two hits and two walks while striking out seven over six scoreless innings.

Impact Castillo was in complete control, holding the Yankees hitless until the fourth inning and limiting them to just two hits overall. The right-hander generated 17 whiffs and leaned heavily on his primary arsenal, throwing 87 of his 95 pitches as either a fastball or slider. Castillo had hitters fooled all night, but his final strikeout was a milestone moment, as he got Aaron Judge to swing through an inside breaking ball for his 1,500th career strikeout before exiting after the sixth inning. The 33-year-old will look to replicate Monday's success in his next scheduled start against the Angels.

Mariners' Opening Day rotation shows how far Seattle's come entering 2026 The Mariners are rolling with Luis Castillo with their No. 5 starter. He was their No. 1 not too long ago.

MARCH 26 • SODOMOJO.COM

Opening season as fifth starter Castillo is slated to make his first start during the Mariners' fifth game of the season Monday versus the Yankees at T-Mobile Park, Adam Jude of The Seattle Times reports.

Impact Emerson Hancock is the Mariners' de facto fifth starter while stepping into the rotation in place of the injured Bryce Miller (oblique), but he'll end up taking the hill for Seattle's fourth game Sunday versus Cleveland while Castillo moves to the back of the schedule. The rotation setup is likely just a means to get Castillo some extra rest after he started the Mariners' spring training finale Monday in San Diego. Castillo covered five innings and tossed 76 pitches in that outing, so he should be ready to handle a relatively normal workload in his 2026 debut.

Strong finish to spring slate Castillo allowed one run on four hits and a walk while striking out five across five innings in Monday's matchup with the Padres.

Impact Castillo finished Cactus League play on a high note, allowing three runs over nine innings in his final two outings. It's certainly an encouraging development after the right-hander struggled to a 27.00 ERA in his first three appearances (six innings). Castillo, who's posted a sub-four ERA in each of his last seven seasons, made a team-high 32 regular-season starts in 2025, finishing with a 3.54 ERA, 1.18 WHIP and 162:46 K:BB across 180.2 innings.
