The Mariners optioned Castano to Triple-A Tacoma on Wednesday.

Castano has yielded five runs with a 3:3 K:BB over five innings in five Cactus League outings. The 27-year-old will likely begin the season in the rotation at Triple-A Tacoma, but if he gets another shot with the big club, it could be as a reliever.

The Athletics optioned Estes to Triple-A Las Vegas on Wednesday.

After overcoming a herniated disc in his lower back, Estes threw 2.2 scoreless innings in Tuesday's Cactus League game against the White Sox in his spring training debut. He now finds himself cut from big-league camp a day later. Estes is ticketed for the Triple-A Las Vegas rotation at the start of the season.

The Cardinals reassigned Zimmermann to minor-league camp Tuesday.

Zimmermann signed with the Cardinals on a minor-league deal in January after spending the 2025 season in the Brewers organization. The southpaw gave up six runs (five earned) in six innings in a late-season spot start with Milwaukee but otherwise spent the entire campaign at Triple-A Nashville, where he produced a 4.11 ERA, 1.23 WHIP and 109:30 K:BB in 138 innings. After falling short in his bid for a spot on the Cardinals' Opening Day roster, Zimmermann is expected to serve as a swingman at Triple-A Memphis to begin the season.

Miller (oblique) will throw a normal bullpen session Wednesday, Daniel Kramer of MLB.com reports.

Miller has previously thrown off the mound at less than full effort, but he'll throw his first standard bullpen session since he came down with inflammation in his left oblique in late February. The Mariners haven't revealed a target date for Miller's return to game action, but it will be close as to whether he can ramp back up in time for Opening Day.

Dobbins (knee) will pitch in another minor-league game later this week, Daniel Guerrero of the St. Louis Post-Dispatch reports.

Returning from last July's right ACL surgery, Dobbins threw four innings and around 65 pitches in a previous appearance on the back fields. He was pleased with how that outing went, saying "a lot of the movement profiles have increased" after "some of the tweaks we've been making." Dobbins will be permitted to field his position in the game later this week, but he will not be allowed to cover first base, as the Cardinals are still being protective of his surgically repaired knee. The 26-year-old is set to open the 2026 season either on the injured list or at Triple-A Memphis, but he's a candidate to see starts for St. Louis later this summer.

The Nationals announced Wednesday that Cavalli will start the team's March 26 season opener versus the Cubs at Wrigley Field.

Injuries forced Cavalli to wait nearly three years in between major-league appearances, but he showed promise in his 10 starts with the Nationals in 2025 with a 4.25 ERA and 40:15 K:BB over 48.2 innings. The 27-year-old sported better velocity last season than he showed prior to Tommy John surgery and has some breakout potential in 2026.

Astros manager Joe Espada said Wednesday that Javier will be away from the club for the next few days while tending to a personal matter, Chandler Rome of The Athletic reports.

Citing privacy, Espada didn't provide any further information regarding Javier's upcoming absence, but the skipper noted that the right-hander will continue to throw while he remains away. Javier tossed 1.2 innings and 52 pitches in his Grapefruit League debut Monday, so as long as he's able to return to the team in time to make another start before spring training ends, he should be able to handle something close to a normal workload when his first turn in the rotation comes up during the regular season.

Matz allowed one hit and one walk in four shutout innings during Tuesday's Grapefruit League game against the Twins. He struck out three.

Matz is now up to six scoreless frames covering two Grapefruit League outings. The 34-year-old left-hander is looking to open his first season with Tampa Bay as part of the starting rotation, which could occasionally give him streaming appeal in deep fantasy leagues for home starts at pitcher-friendly Tropicana Field based on matchups. Last regular season, Matz posted a quality 3.05 ERA, 1.10 WHIP and 59:11 K:BB over 76.2 innings between St. Louis and Boston.

Ryan (back) threw three scoreless innings in his spring debut Tuesday with two walks and no strikeouts. "We'll talk and check in this week and see where we're at, but I think things are looking pretty good," Ryan said of his chances to pitch in the WBC according to Declan Goff of SKOR North.

Ryan said his back felt good during the outing where he threw 48 pitches. It remains to be seen if he'll join Team USA for the second round of the WBC, but it sounds like he has a good chance to be ready for Opening Day. Ryan was scratched ahead of his first scheduled spring start Feb. 21 when he experienced tightness on the right side of his back. An MRI revealed only inflammation and he was able to begin throwing soon afterward.

McDonald has allowed two hits and a walk while striking out seven across six scoreless innings in three Cactus League appearances, and he is making a strong case to open the 2026 campaign in the Giants' bullpen, Maria Guardado of MLB.com reports.

McDonald was recalled from Triple-A Sacramento in September of last season, recording a 1.80 ERA, 1.00 WHIP and 14:2 K:BB across 15 innings in three big-league appearances, including two starts. The right-hander has impressed this spring, and while there isn't expected to be room for him in the starting rotation just yet, he has a good chance to open the season in the bullpen. If injuries arise among San Francisco's starters during the season, the 25-year-old would be a candidate to move into the rotation.
