  • Mariners' Luis Castillo: Works seven innings in loss

    Castillo (3-9) allowed three runs on four hits and two walks while striking out three over seven innings to take the loss Tuesday versus the Reds.

    Two of the four hits Castillo allowed were solo home runs, though it was Sal Stewart's sacrifice fly in the fifth inning that ultimately sealed the loss for Seattle. This was a third straight defeat for Castillo, who has allowed nine runs over 18 innings with an 11:4 K:BB in that span. For the season, he has a 4.85 ERA, 1.33 WHIP and 84:30 K:BB through 94.2 innings across 19 appearances (16 starts). Castillo is tentatively lined up for a tough road start versus the Dodgers next week, though he is a candidate to be traded if the Mariners want to clear their logjam of starters.

  • Mariners' Luis Castillo: Tagged with loss Friday

    Castillo (3-8) took the loss Friday against the Rays, allowing four runs on nine hits and a walk while striking out four batters across five innings.

    Castillo allowed three homers and has dropped three of his last five starts. However, the veteran hurler has given up two or fewer runs in seven of his last nine outings, so he's been pitching well lately, all things considered. Castillo saw his season ERA rise to 4.93 after this start, but he has a more respectable 3.90 ERA in six starts and 32.1 innings since the beginning of June.

  • Mariners' Luis Castillo: Earns quality start in loss

    Castillo (3-7) allowed two runs on five hits and a walk while striking out four over six innings to take the loss versus the Blue Jays on Friday.

    Castillo was mostly fine, but he allowed both runs and four of the five hits on his line during the third inning. The Mariners mustered just six baserunners in the game, giving Castillo virtually no support. He has posted back-to-back quality starts but still has just one win in his last five outings. Castillo is at a 4.79 ERA, 1.33 WHIP and 77:27 K:BB through 82.2 innings over 17 games (14 starts) this season. The veteran right-hander is tentatively projected for a road start in Miami next week.

  • Mariners' Luis Castillo: Quality start in win

    Castillo (3-6) earned the win against the Guardians on Friday, giving up one earned run on four hits and a walk while striking out four batters across six innings.

    A first-inning RBI double from Kahlil Watson gave the Guardians an early 1-0 lead, but that ended up being the only run Cleveland would score against Castillo, who allowed just three additional baserunners before departing the game after six innings. Friday marked the 33-year-old's first win since the end of May, as well as his first quality start since his season debut March 30. He'll take a 4.93 ERA and 1.36 WHIP into his next start against the Angels, who have turned in a .758 OPS since the beginning of June.

  • Mariners' Luis Castillo: Roughed up in relief outing

    Castillo allowed five runs (four earned) on seven hits and struck out four without walking a batter over four innings of relief in Friday's 6-2 loss to the Red Sox.

    Castillo wasn't tagged with the loss, as that went to Bryce Miller. The Mariners' offense didn't give much support to either pitcher, but Castillo didn't do his part to keep the game close after a four-run seventh inning. He has now allowed 11 runs (seven earned) across 15.1 innings in June. Both Castillo and Miller are expected to work in traditional starts at some point during the Mariners' six-game road trip next week.

  • Mariners' Luis Castillo: Part of pitching tandem Friday

    Mariners general manager Justin Hollander said Tuesday that Castillo will work in relief behind starter Bryce Miller during Friday's game against the Red Sox as part of a piggyback arrangement, Adam Jude of The Seattle Times reports.

    Castillo and Miller made standalone starts in both of their last two appearances, but the two will shift back into a tandem setup Friday. They previously worked in a piggyback arrangement on three occasions back in May, with Miller covering between five and 5.2 frames in those games and Castillo ranging between 2.1 and five innings. According to Hollander, the Mariners plan to condense their rotation to five through the All-Star break, with all six of their starters rotating through and being part of at least one piggyback game over the next month. Hollander noted that it was merely a coincidence that the new staff-wide piggyback plan is beginning with Miller and Castillo, so both are expected to be separated and make traditional starts when their turn in the pitching schedule comes up again next week.

  • Mariners' Luis Castillo: Fans four in sixth loss

    Castillo (2-6) took the loss Saturday against the Nationals, allowing five runs (two earned) on seven hits and two walks in 5.2 innings. He struck out four.

    A throwing error by Josh Naylor kept three earned runs of Castillo's ledger, but Washington got to the hurler for two more runs in the fifth frame. The 33-year-old right-hander has worked at least four innings while yielding two earned runs or fewer in four consecutive outings, so he's performing a bit better as of late. Castillo will try to further improve on a 5.00 ERA, 1.38 WHIP and 65:25 K:BB over 66.2 innings into his next scheduled appearance against Boston.

  • Mariners' Luis Castillo: Yields one run in no-decision

    Castillo did not factor into Sunday's decision against the Tigers, allowing one run on two hits and one walk while striking out five across 5.2 innings.

    Castillo had worked behind Bryce Miller in each of his three prior outings, but the former was on the mound for the start of Sunday's series finale. Castillo limited the Tigers to just three baserunners across five-plus innings while inducing 12 whiffs, and he reached 100 pitches for the third time this season. He now sits at a 5.16 ERA and 1.36 WHIP across 61 innings, and his next appearance is slated for next weekend on the road against the Nationals.

  • Mariners' Luis Castillo: Receiving start Sunday

    Castillo is slated to start Sunday's game against the Tigers, Adam Jude of The Seattle Times reports.

    Castillo and Bryce Miller worked in tandem in each of the previous three turns through the rotation, but both pitchers will receive standalone starts during the final two games of the series in Detroit. Though he currently maintains an ugly 5.53 ERA and 1.45 WHIP on the season, Castillo took some steps forward over his last two outings, covering nine innings between a start and relief appearance behind Miller while striking out nine batters and yielding two runs (one earned) on four hits and four walks. Mariners manager Dan Wilson hasn't outlined his plans for the rotation beyond this weekend, so Castillo could need another positive showing in Detroit to avoid falling back into a piggyback arrangement with Miller or shifting into a full-time bullpen role.

  • Mariners' Luis Castillo: Snags extra-inning win

    Castillo (2-5) allowed two runs (one earned) on two hits and two walks with three strikeouts over five innings of relief, earning the win despite taking a blown save Sunday versus the Diamondbacks.

    Castillo couldn't hold the 1-0 lead in the sixth inning after Bryce Miller's five frames of one-hit ball. This was still a positive showing for Castillo, who has given up just four runs (three earned) over 11.1 innings while adding a 13:6 K:BB over his last three appearances. He has a 5.53 ERA, 1.45 WHIP and 56:22 K:BB across 55.1 innings through 12 outings (10 starts) this year. The Mariners' fifth spot in the rotation is set to come up again on the road versus the Tigers -- if the team continues to deploy a tandem, Castillo and Miller would likely share another game despite the pitchers' discomfort with the ongoing arrangement.

  • Mariners' Luis Castillo: Working behind Miller on Sunday

    Castillo is slated to work out of the bullpen and will piggyback starter Bryce Miller during Sunday's game against the Diamondbacks in Seattle, Adam Jude of The Seattle Times reports.

    Though both Castillo and Miller have expressed a reluctance to being used in a piggyback arrangement, the two pitchers will nonetheless operate in a tandem for a third consecutive turn through the rotation. The setup worked well the last time out Monday in Sacramento, with Castillo starting the game and delivering one of his better efforts of the season, as he struck out six and allowed just two hits and two walks over four scoreless frames. Miller followed with five innings of two-run ball and was credited with the win, but Castillo should have better odds of factoring into the decision Sunday while he and Miller are used in the opposite order. The Mariners will reassess their rotation plans after Sunday's contest, and Castillo may need another strong showing against Arizona to ensure that he avoids moving into a full-time relief role.
