Mariners' Luis Castillo: Gives up five runs against Dodgers
Castillo allowed five runs on 11 hits and two walks while striking out two over five innings in a no-decision versus the Dodgers on Tuesday.
Castillo gave up multiple home runs for the third start in a row, as Shohei Ohtani led off the bottom of the first inning with a long ball and Max Muncy went yard in the fifth. This was the first time Castillo had allowed five earned runs since April. July was a rough month for the veteran, who gave up 14 runs over 23 innings across his four outings. On the year, he has a 5.06 ERA, 1.39 WHIP and 86:32 K:BB across 99.2 innings over 20 games (17 starts). Castillo is tentatively projected to make his next start at home versus the Tigers, but that is a loose projection given the likelihood the Mariners move a pitcher before the trade deadline.

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.
