Castillo (1-4) earned the win Thursday against the Astros, allowing three runs on four hits and three walks in 5.2 innings. He struck out six.

Castillo was working on a bounce-back start Thursday, giving up a lone run over his first five frames, but the Astros got to him for two more runs in the sixth inning to make his line more middling. The Mariners might have left the 33-year-old right-hander in the game for a bit too long considering that the hurler tossed a season-high 108 pitches. Castillo has now yielded at least three runs in three straight outings and six of his last eight, posting a disappointing 6.34 ERA, 1.57 WHIP and 43:16 K:BB over 44 innings in 2026. He's tentatively lined up to piggyback with Bryce Miller early next week versus the White Sox, which would mark Castillo's first career relief appearance if he works as the secondary pitcher.

Astros manager Joe Espada said Thursday that Teng will be part of a six-man rotation moving forward, Chandler Rome of The Athletic reports.

Circumstances could alter the Astros' plans down the line, but Houston is planning to go with a six-man setup indefinitely. Espada said that he expects Teng -- who threw 63 pitches over three innings in a start Sunday in Cincinnati -- to be able to handle 80-to-85 pitches during his next start Saturday versus the Rangers. Teng holds a 3.12 ERA, 1.08 WHIP and 23:8 K:BB over 26 innings covering two starts and 13 relief outings this season.

The Athletics acquired Suarez from the Mariners on Thursday in exchange for cash considerations.

Suarez had been designated for assignment by Seattle and will remain in the division after being shipped to the A's. The left-hander does not have minor-league options remaining, so he will join the bullpen as a long reliever.

Mize (thigh) could return from the 15-day injured list to start Saturday's game against the Blue Jays, Chris McCosky of The Detroit News reports.

Mize has been sidelined since late April with a right adductor strain. He has not made a rehab start, but the right-hander threw a live batting practice session earlier this week and it appears he could skip a rehab assignment. Mize was excellent in his first six outings this season before getting hurt, posting a 2.90 ERA and 35:11 K:BB over 31 innings. If Mize is able to start Saturday, he figures to be somewhat limited from a pitch-count perspective.

Miller (oblique) allowed two runs on eight hits and a walk while striking out three over 5.1 innings in a no-decision versus the Astros on Wednesday.

Miller missed over a quarter of the season while recovering from a left oblique strain. He threw 58 of 81 pitches for strikes in his season debut, so he may have had a slight workload limitation in place. That will likely continue in his next start, tentatively expected to be against the White Sox, as Miller and Luis Castillo are expected to work as a tandem in that game to buy the Mariners some time to sort out what to do with their rotation, which has six healthy starters. As long as Miller pitches well, he's likely to be a starter moving forward, though he'll also need to stay healthy as he tries to bounce back from an ugly 5.68 ERA and 1.41 WHIP across 90.1 innings in the 2025 regular season, which was disrupted by elbow troubles.

McCullers allowed two runs on seven hits and two walks while striking out six over 5.1 innings in a no-decision versus the Mariners on Wednesday.

McCullers put in a decent effort Wednesday after his previous start was cut short by a blister on his pitching hand. This was one of his better outings this season, though he still allowed solo home runs to J.P. Crawford and Luke Raley. McCullers has a 6.86 ERA, 1.53 WHIP and 43:22 K:BB through 39.1 innings over eight starts this season. He's tentatively projected for a road start in Minnesota his next time out.

The Twins will push back Prielipp's next start by a day or two and will call up Zebby Matthews to start Thursday's game against the Marlins, Bobby Nightengale of The Minnesota Star Tribune reports.

The Twins are looking to limit Prielipp's usage given that he's never pitched more than 83.2 innings in a professional season and has had two career Tommy John surgeries on his resume. The left-hander has pitched well in his first four big-league starts, posting a 3.32 ERA, 1.00 WHIP and 21:7 K:BB across 19 innings.

Cease did not factor into the decision Wednesday against the Rays, allowing a run on three hits and three walks over seven innings. He struck out nine.

While Toronto failed to take the lead until the 10th inning, leaving Cease with a no-decision, it was another excellent outing from the right-hander, who's now gone seven innings in each of his last three starts. Cease's ERA is down to 2.41 across nine starts (52.1 innings) with a 1.18 WHIP and 75 strikeouts, good for second most in the majors. He'll look to keep rolling his next time out, tentatively lined up for next week on the road against the Yankees.

Gray (4-1) earned the win Wednesday over the Phillies, allowing one run on two hits and a walk over six innings. He struck out six.

It was a strong performance from Gray, with Philadelphia's lone run coming on a Justin Crawford homer in the third inning. In two starts since returning from the IL, Gray has allowed just one run on six hits over 11 innings. Overall in 2026, his ERA sits at 3.18 with a 1.15 WHIP and 21:8 K:BB across seven starts (34 innings). Gray will look to keep rolling in his next outing, which is currently lined up for next week in Kansas City.

Valdez did not factor into Wednesday's decision against the Mets, allowing two runs on five hits and two walks while striking out seven across 6.2 innings.

Valdez took to the mound Wednesday after serving a five-game suspension for throwing at Trevor Story during the Tigers' 10-3 loss to the Red Sox on May 5. Valdez limited the Mets to just one run through six innings but was tagged for another run in the seventh that tied the game at 2-2. He logged 17 first-pitch strikes and generated 11 whiffs on 106 pitches (72 strikes), which is the first time he's cracked the century mark this season. It was the sixth quality start of the season for Valdez, who has a 4.32 ERA, 1.36 WHIP and 42:17 K:BB across 50 innings. He's lined up to face the Guardians at home next week.
