Mariners writer's clever Bryce Miller rotation solution would be a missed opportunity Luis Castillo and Bryce Miller in a piggyback? Solid idea, but the Mariners can do better.

Could get bumped from rotation The Mariners could remove Castillo from the rotation when Bryce Miller (oblique) returns next week, Adam Jude of The Seattle Times reports.

Impact It's just one option the team is mulling, as Miller and Emerson Hancock are also being considered for the bullpen or piggyback roles. It would be an easy decision to bump Castillo from the rotation if it were based purely on performance, as he's posted a 6.29 ERA, 1.66 WHIP and 31:13 K:BB over 34.1 innings in his first seven starts. However, Castillo has never pitched in relief at the major-league level, while Miller and Hancock both have. A six-man rotation is also under consideration. Castillo will start Saturday in Chicago against the White Sox in what could be his final opportunity to convince the Mariners he should remain in the rotation.

Takes another loss Castillo (0-3) allowed four runs on six hits, two walks and a hit-by-pitch while striking out five over six innings to take the loss Sunday versus the Royals.

Impact Castillo was doing fine until the fourth inning, when he allowed four straight batters to reach base to open the inning. Three of them came around to score, and the Royals tacked on an extra run in the sixth. Castillo has allowed at least four runs in five of his seven starts this season, though this is the third time he's allowed four earned runs. He has a 6.29 ERA, 1.66 WHIP and 31:13 K:BB through 34.1 innings. Until Castillo is able to limit baserunners better, he is likely to continue having trouble preventing runs. His next start is projected to be on the road versus the White Sox.

Surrenders seven runs Castillo (0-2) took the loss Monday, allowing seven runs on seven hits and two walks over five innings against Minnesota. He struck out three.

Impact Castillo worked a clean first inning but struggled from there, allowing four runs in the third inning, highlighted by a three-run homer from Kody Clemens. Known for his consistency with a career 3.61 ERA and just one full season above 4.00, Castillo is off to a rough start in 2026, posting a 6.35 ERA and 1.73 WHIP with opponents hitting .317 across 28.1 innings (six starts). He'll look to get back on track in his next outing, which is tentatively scheduled for Sunday against Kansas City.

Seven Teams, Seven Slow Starts. What's Behind MLB's Most Surprising Struggles?

Fans six in no-decision Castillo tossed five innings against the Athletics on Tuesday, allowing two runs on five hits and two walks while striking out six batters.

Impact Castillo gave up a run in the first inning and another in the fourth but kept Seattle in the contest throughout his time in the game. The right-hander wasn't very efficient, however, as he needed 95 pitches to complete five frames. That was partly because he had his swing-and-miss stuff working -- Castillo recorded 14 whiffs, and his six punchouts were his second-most through five starts so far this season. The veteran hurler is still looking for his first victory, which he'll try to notch in what's projected to be a matchup versus Minnesota on the road his next time out.

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.
