Mariners' Luis Castillo: Another rough outing
Castillo (8-7) took the loss Wednesday against the Phillies, allowing three runs on 10 hits and two walks over four innings. He struck out two.
Castillo has now allowed nine runs on 19 hits across just eight innings in his last two starts after pitching to a 2.25 ERA in his previous eight outings (48 innings). Overall, Castillo's ERA sits at 3.57 with a 1.27 WHIP and 127:40 K:BB across 26 starts (146.1 innings). The 32-year-old right-hander will look to get back on track his next time out, currently scheduled to come next week at home against the Padres.

Mariners' Luis Castillo: Hit hard in no-decision
Castillo came away with a no-decision in Friday's 11-9 win over the Mets, surrendering six runs on nine hits -- including three home runs -- and a walk over four innings. He struck out five.
The ball was flying at Citi Field, as the Mariners set a club record with nine doubles, while the two teams combined for five total homers. Castillo did his part to add to the fireworks, serving up two longs balls to Francisco Lindor and another to Juan Soto. It's the second time this season he's been taken deep three times in the same game, but his 10.4 percent HR/FB rate on the season is actually his lowest mark since 2022. Castillo could have trouble keeping the ball in the park in his next start as well, which lines up to come on the road next week in Philadelphia.

Mariners' Luis Castillo: Settles for no-decision Friday
Castillo didn't factor into the decision in Friday's 3-2 win over the Rays, giving up two runs on five hits over seven innings. He struck out five without walking a batter.
All the damage off the veteran righty came on solo shots by Brandon Lowe in the first inning and Junior Caminero in the sixth, but all of Seattle's offense came on a three-run blast by Cal Raleigh in the eighth. Castillo delivered his 14th quality start of the year on 99 pitches (72 strikes), and he's allowed three earned runs or fewer in eight straight trips to the mound, posting a 2.25 ERA, 1.02 WHIP and 45:7 K:BB through 48 innings over that span. He'll look to get back in the win column in his next outing, which is scheduled to come on the road next weekend against the Mets.

Mariners' Luis Castillo: Labors in no-decision
Castillo did not factor into the decision in Saturday's 6-4 extra-innings loss to the Rangers, allowing two runs on four hits and one walk with four strikeouts over 4.1 innings.
Castillo allowed both of his runs in the third inning and failed to complete five frames for just the second time in 23 starts, throwing only 51 of 87 pitches for strikes. Still, the veteran has now surrendered three earned runs or fewer in seven straight outings, a stretch that includes four wins and four quality starts. He'll take a 3.22 ERA, 1.21 WHIP and 115:37 K:BB across 131.1 innings into a home matchup with the Rays next weekend.

Mariners' Luis Castillo: Tosses seven sterling frames
Castillo (8-6) earned the win over the Athletics on Monday, allowing one run on five hits and no walks while striking out four batters over seven innings.
Castillo was more crafty than overpowering in the outing, as he notched just six whiffs and four punchouts. The veteran right-hander allowed only six baserunners (on five hits and one hit batsman), with the Athletics' lone run coming on a fielder's choice in the sixth frame. This was Castillo's 13th quality start of the campaign, tied for 11th-most in the majors. He's putting together another steadily reliable season, posting a 3.19 ERA, 1.21 WHIP and 111:36 K:BB through 127 innings spanning 22 starts.

Castillo (7-6) took the loss Wednesday against the Brewers, allowing six runs (three earned) on 10 hits over five innings. He struck out seven.

Overall, Castillo sports a 3.30 ERA with a 1.24 WHIP and 107:36 K:BB over 21 starts (120 innings) this season. He'll look to get back on track in his next outing, currently scheduled for next week against the A's.

Mariners' Luis Castillo: Delivers best outing of 2025
Castillo (5-5) picked up the win Saturday against the Pirates, striking out eight and giving up just two hits and no walks across seven scoreless innings.
The eight punchouts are a season high for Castillo, who got back in the win column for the first time since May 19 against the White Sox. The veteran right-hander has seen his strikeout numbers take a dip in 2025 with a career-low 7.6 K/9, but he's still been plenty effective through 18 starts with a 3.31 ERA and 1.22 WHIP over 103.1 innings.
