The Astros selected Roa's contract from Triple-A Sugar Land on Wednesday.

Roa came to Astros camp as a non-roster invitee and won a spot by allowing just one run with a 13:0 K:BB over 9.2 Grapefruit League innings. The righty has just two games of big-league experience under his belt and should be used in low-leverage situations.

The Brewers optioned McGee to Triple-A Nashville on Wednesday.

McGee had been in the mix for a spot in the Brewers' bullpen but ultimately didn't make the cut. He should be one of the first relievers called upon from the minors when the club needs bullpen help.

The Cubs placed Steele (elbow) on the 60-day injured list Wednesday.

Steele is progressing as anticipated after undergoing UCL revision surgery back on April 18, 2025, but he'll still need at least the first two months of the 2026 season to complete the lengthy recovery process. The southpaw checked off a major box in his rehab program by facing live hitters in batting practice sessions just under two weeks ago. He'll likely continue to gradually increase the volume and intensity of his pitching in live BP sessions and simulated games over at least the next few weeks before eventually embarking on an extended minor-league rehab assignment.

The Cardinals placed Dobbins (knee) on the 15-day injured list Wednesday.

Dobbins is still working his way back from July surgery to repair a torn ACL in his right knee. Though he's been able to steadily build up his pitch count throughout the spring through live batting practice sessions and simulated games, he's not yet been cleared for full fielding and agility drills. Once he clears that hurdle in the recovery process, Dobbins may not require an extensive rehab assignment, but the Cardinals aren't guaranteed to have a spot in the rotation available for him upon his return from the IL.

The Cubs placed Hodge (elbow) on the 15-day injured list Wednesday.

Hodge came down with a right flexor strain in early March. He is aiming to play catch around April 1, but he'll have been shut down nearly a month by that time, so the buildup will take a while.

The Phillies placed Wheeler (shoulder) on the 15-day injured list Wednesday.

Wheeler is still working his way back from last September's venous thoracic outlet syndrome surgery. He is slated to begin a rehab assignment with Triple-A Lehigh Valley on Saturday. Wheeler will be eligible for activation April 6, and while he might not be ready by that date, he is on track to return sometime in April.

The Guardians placed Gaddis (forearm) on the 15-day injured list Wednesday.

Gaddis has been dealing with forearm tightness during spring training and won't be available to begin the season. The right-hander was able to see game action at the end of camp and should be able to begin a minor-league rehab assignment soon.

The Cubs placed Wicks (elbow) on the 15-day injured list Wednesday.

Left elbow inflammation will keep Wicks sidelined for at least the first couple weeks of the regular season. He has resumed throwing off the mound, but it's unclear when he'll be ready for game action.

Arizona placed Walston (elbow) on the 60-day injured list Wednesday.

Walston will open a second consecutive season on the 60-day injured list after he was shelved throughout the 2025 campaign after undergoing Tommy John surgery March 26 of last year. Per Alex Weiner of ArizonaSports.com, Walston was spotted throwing off flat ground Feb. 10, but it's unclear if the southpaw has progressed to mound work since then. In any case, Walston will be out for at least the first two months of the 2026 campaign while he continues to build back up following surgery.

The Diamondbacks placed Mena (shoulder) on the 60-day injured list Wednesday.

Mena didn't pitch after June 6 last season after straining his right shoulder and had received a clean bill of health heading into spring training before aggravating the injury early in camp. The right-hander remains shut down from throwing and will now be shelved for at least the first two months of the season while he continues to rehab the injury.
