The Orioles placed Kittredge (shoulder) on the 15-day injured list Wednesday.

Kittredge developed right shoulder inflammation in early March. He will be eligible for activation April 6, and at last check the Orioles were expecting him to be ready to go on that date. Once healthy, Kittredge will fill a setup role.

The Rays placed Uceta (shoulder) on the 15-day injured list Wednesday.

Uceta came down with a right shoulder impingement in February. He resumed mound work in mid-March but still has some building up to do. Uceta has not pitched in a game since last season, so he will require a few rehab appearances once he's deemed game-ready.

Phillips (elbow) threw a bullpen session to a squatting catcher March 17, per MLB.com.

Phillips had previously been throwing only to a standing catcher, so this was a notable step forward in his recovery from the Tommy John surgery he underwent last June. The righty reliever is beginning the season on the 60-day injured list and is expected to miss most of the season, though he could be ready for game action sometime in the second half.

The Giants selected Kilian's contract from Triple-A Sacramento on Wednesday.

Kilian won a bullpen job as a non-roster invitee after yielding just one run with an 11:2 K:BB over 9.1 innings during Cactus League play. The 28-year-old is likely to operate in middle relief initially, but it wouldn't be a surprise if he pushes for a more high-profile role as part of a Giants bullpen that's in flux.

The Giants reassigned Fulmer to minor-league camp Wednesday, Justice delos Santos of The San Jose Mercury News reports.

Fulmer joined the Giants as a non-roster invitee in February, and he had a solid showing during spring training with five earned runs allowed and a 16:4 K:BB over 10.1 innings. He made just three regular-season appearances between the Cubs and Red Sox last season after missing all of 2024 due to UCL revision surgery.

The Twins selected Laweryson's contract from Triple-A St. Paul on Wednesday.

Laweryson won a spot in the Twins' bullpen after posting a 1.17 ERA and 7:1 K:BB in 7.2 innings this spring as a non-roster invitee. The 27-year-old will be part of an unsettled relief corps in Minnesota, giving him a chance to pitch his way into leveraged appearances.

The Diamondbacks designated Holman for assignment Wednesday.

Holman was pushed off the 40-man roster with Arizona needing to clear three spots for infielder Ildemaro Vargas and right-handers Jonathan Loaisiga and Joe Ross, all of whom will be included on the Opening Day squad. Arizona previously scooped up the 25-year-old Holman off waivers from the Athletics in February after he turned in a 5.09 ERA, 1.52 WHIP and 17:9 K:BB over 23 big-league innings last season.

The Astros placed Hader (biceps) on the 15-day injured list Wednesday.

Hader resumed mound work in early March but has not made an appearance in a game since he was diagnosed with left biceps tendinitis in early February. The southpaw is sure to require a rehab assignment before rejoining Houston's active roster. Bryan Abreu will be the Astros' closer while Hader is sidelined.

The Rangers placed Bradford (elbow) on the 15-day injured list Wednesday.

Bradford is still working his way back from an internal brace procedure he had last June. The left-hander is expected to be ready for a rehab assignment soon and is looking at a potential season debut around May 1.

The Astros placed Pearson (elbow) on the 15-day injured list Wednesday.

Pearson had to be shut down in early March after feeling soreness in his surgically repaired right elbow. It's not clear whether he's resumed throwing, and even if he has he's surely looking at longer than a minimum stay on the IL.
