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.

The Diamondbacks placed Kelly on the 15-day injured list Wednesday due to left intercostal nerve irritation.

While Kelly won't be part of the Arizona's Opening Day rotation, he may need to miss only two or three turns before making his 2026 debut. Despite being set back by the injury in camp, Kelly was able to make three starts during spring training and most recently covered 52 pitches and two-plus innings Monday. He's expected to build on that workload in a rehab start with Triple-A Reno on April 3 and is tentatively scheduled for another minor-league tuneup outing April 8 before likely returning from the IL thereafter.

Schmidt (elbow) is tentatively slated to begin throwing bullpens before the end of March and could face hitters in April or May, per MLB.com.

Schmidt did some throwing during spring training but primarily threw off flat round. He seems to be doing fine in his recovery from the internal brace procedure he underwent last July, though the right-hander isn't expected to be ready to rejoin the Yankees until the second half of the season.

Canning (Achilles) pitched against the Mariners in a "B" game on a back field March 20, tossing a scoreless inning with three strikeouts, per MLB.com.

The appearance was Canning's first in a game setting since he tore his Achilles last June. The right-hander was with the Mets at the time, and he signed a one-year contract with San Diego in mid-February of this year. Canning will begin the campaign on the injured list but could be ready to join the Padres' rotation before the end of April.

The Red Sox placed Sandoval (elbow) on the 15-day injured list Wednesday.

Though Sandoval (elbow) didn't make any Grapefruit League appearances, he was able to throw a three-inning simulated game at extended spring training Monday and should be on track to begin an extended rehab assignment shortly after the minor-league season gets underway this weekend. Sandoval -- who is working his way back from June 2024 internal brace surgery -- could be ready to return from the IL around mid-to-late April, but it's unclear if he'll have a spot in the Boston rotation waiting for him once he's activated from the IL.

The Red Sox placed Crawford (wrist) on the 15-day injured list Wednesday.

Crawford didn't make any appearances in the Grapefruit League while completing his recovery from the right wrist surgery he underwent last July. However, the right-hander was able to cover a few innings in a minor-league spring training game earlier this week, so he could be ready to head out on an extended rehab assignment shortly after the minor-league season gets underway. Crawford isn't expected to be ready to return from the IL until late April or early May, and it's not clear if he'll be in line for a spot in the Boston rotation once he gets activated.

Atlanta placed Waldrep (elbow) on the 15-day injured list Wednesday.

Waldrep isn't expected to be available to make his season debut until June or July after he underwent an arthroscopic procedure Feb. 23 to remove loose bodies from his right elbow. Atlanta could shift him to the 60-day IL at some point in the coming weeks when the team needs to free up another spot on the 40-man roster.
