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.

EDGE Analysis

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.

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.

EDGE Analysis

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.

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.

EDGE Analysis

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.

EDGE Analysis

The 10 hits allowed matched a season high for Castillo, who would take his first loss since June 18 -- the right-hander had pitched to a stellar 1.46 ERA in four starts (24.2 innings) prior to Wednesday. 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.

Castillo (7-5) allowed three hits and two walks while striking out seven over 6.2 scoreless innings to earn the win over the Astros on Friday.

EDGE Analysis

Castillo has won three straight starts, allowing just three runs over 18.2 innings in July. The right-hander threw 66 of 100 pitches for strikes in this outing, which was his fifth scoreless performance of the campaign. Castillo has been in peak form in 2025 with a 3.21 ERA, 1.21 WHIP and 100:36 K:BB through 115 innings over 20 starts. He's projected for a home start versus the Brewers next week.

Castillo (6-5) earned the win Friday, allowing three runs on six hits and two walks over five innings while striking out six in the 12-3 victory over the Tigers.

EDGE Analysis

Castillo shined early, yielding just one earned run through the first five innings before running into trouble opening the sixth, allowing back-to-back hits and another run before being removed with a runner on third. The 32-year-old entered the matchup coming off his best start of the season and has now posted a 3.60 ERA with 33 strikeouts and 11 walks over his last six outings.

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.

EDGE Analysis

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.

Castillo didn't factor into the decision Sunday against Texas, allowing one run on seven hits and two walks with four strikeouts over six innings.

EDGE Analysis

Castillo pulled himself out of a rough patch Sunday, snaring a quality start and not allowing a home run. The 32-year-old had allowed 16 runs (14 earned) in 22 innings over his previous four starts. He gave up eight home runs during that stretch after having yielded merely four round trippers in his first 12 starts. On the year, Castillo owns a 3.55 ERA, and he's scheduled to face the Pirates next time out.

Castillo allowed five runs on seven hits and two walks while striking out three over five innings in Tuesday's win over the Twins. He did not factor into the decision.

EDGE Analysis

Castillo was staked a five-run lead in the third inning and gave it all right back. Kody Clemens took him deep in the third before the Twins would tack on four more runs in the fourth. Castillo has given up a home run in four consecutive outings and he's allowed at least seven hits in three of his last six starts. Castillo is winless since May 19 and will look to change that this weekend against the Rangers.

Castillo (4-5) took the loss Wednesday as the Mariners fell 3-1 to the Red Sox, giving up three runs on three hits and two walks over six innings. He struck out five.

EDGE Analysis

All the damage off Castillo came on balls that left the yard, as Marcelo Mayer launched a solo shot off the right-hander in the second inning before Trevor Story lofted a two-run homer in the fourth. It's the third straight start in which Castillo has been taken deep multiple times, a stunning regression after he's served up just one homer over his prior eight outings and 47 innings. He'll take a 3.38 ERA, 1.24 WHIP and 72:28 K:BB through 85.1 innings into his next start, which is scheduled to come on the road early next week in Minnesota.
