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.

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.

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.

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

Smith-Shawver is still on the mend from the Tommy John surgery he underwent June 9 of last year and isn't expected to be ready to pitch for Atlanta until late in the 2026 season, if at all. Atlanta will eventually move him to the 60-day IL when it needs to open up another spot on the 40-man roster.

The Reds recalled Franco from Triple-A Louisville on Wednesday.

Franco was cut from big-league camp in early March, but he's now back to absorb the roster spot of the injured Caleb Ferguson (oblique). When/if the righty gets into a game, it will be his major-league debut.

Atlanta placed Strider (oblique) on the 15-day injured list Wednesday.

Manager Walt Weiss had previously confirmed Monday that Strider would be headed to the IL after the right-hander strained his left oblique after making a start in a minor-league spring game against the Red Sox last week. Though Weiss is optimistic that Atlanta got out in front of Strider's injury before it worsened, the 27-year-old isn't a lock to be activated from the IL when first eligible April 6. Jose Suarez is the leading candidate to enter the rotation as Atlanta's new No. 5 starter while Strider is on the mend.

The Reds placed Lodolo (finger) on the 15-day injured list Wednesday.

Lodolo had been slated to pitch during the Reds' first series of the season but will instead hit the shelf after he exited his final Grapefruit League start last weekend when he developed a blister on his left index finger. The southpaw was able to resume playing catch Tuesday, so assuming his finger presents no further issues for him while he builds back up, he could be ready to return from the IL when first eligible April 7.

The Dodgers placed Snell (shoulder) on the 15-day injured list Monday.

Snell has been working his way back from left shoulder fatigue, an issue that's lingered since last season. He's begun throwing off a mound but will not be ready for his season debut until late May, at the earliest. The Dodgers could eventually shift Snell to the 60-day IL when/if they need a 40-man roster spot.

The Dodgers placed Miller (shoulder) on the 60-day injured list Monday.

Miller was slowed by shoulder soreness this spring, and the injury is evidently bad enough that the Dodgers opted to go ahead and put him on the 60-day IL. The righty converted to a relief role in the minors last season and is surely headed back to Triple-A Oklahoma City once he returns to full health.
