Arizona Diamondbacks manager Torey Lovullo said that right-handed reliver Justin Martinez was not available in Sunday's victory over the Chicago Cubs due to "fatigue" and a recent heavy workload. Team trainers told Lovullo that Martinez needed another day off, but the team didn't send him for any testing or imaging. The 23-year-old Dominican last threw a third of an inning on April 17 to pick up a hold against the Miami Marlins, so it's a bit curious that Lovullo mentioned his recent heavy workload. With left-hander A.J. Puk (elbow) going on the 15-day injured list on Saturday and Martinez being unavailable on Sunday, righty Drey Jameson picked up the save on Easter against the Cubs. Martinez should be available to pitch in Tuesday's series opener against the Tampa Bay Rays, but if he isn't and is dealing with an injury, Jameson, Shelby Miller and Jalen Beeks could be options for saves in Arizona.

The Baltimore Orioles announced on Tuesday that they placed right-hander Cody Poteet (shoulder) on the 15-day injured list (retroactive to April 21) with right-shoulder inflammation and recalled right-hander Brandon Young from Triple-A Norfolk in a corresponding move. Poteet's right shoulder was apparently giving him problems in his first outing of the season on Sunday against the Cincinnati Reds, when he allowed five earned runs on six hits while walking two and striking out one in 2 2/3 innings of work out of the bullpen in a 24-2 shellacking. It's unclear how long the 30-year-old veteran reliever will be on the injured list, but fantasy managers can continue to ignore him whenever he gets back. Poteet has never thrown more than 30 2/3 innings at the big-league level since debuting with the Miami Marlins back in 2021.

The Double-A Chesapeake Baysox announced that Baltimore Orioles left-hander Trevor Rogers (knee) will make his first minor-league rehab appearance for them on Wednesday against the Double-A Altoona Curve. Rogers has been rehabbing from a subluxation of his right knee that he suffered way back in January, and he's now ready to pitch in games as he attempts to make his way back to the Orioles' starting rotation. However, the 27-year-old southpaw is expected to need a lengthy rehab assignment that could stretch well into May. Even when Rogers is deemed fully healthy, there's no guarantee he'll have a rotation spot waiting for him at the big-league level. The former first-rounder by the Miami Marlins in 2017 had a rough 7.11 ERA and 1.84 WHIP in four starts for the O's late last year and was eventually shipped to the minors.

In his third minor-league start on Sunday, Baltimore Orioles right-hander Kyle Gibson went five innings and allowed two runs (one earned) while allowing a solo home run, walking two and striking out five to pick up a win for High-A Aberdeen. Gibson isn't injured, but he opened the 2025 season in the minors to build up his arm after not appearing in any spring training games after signing with Baltimore late. The 37-year-old veteran has now allowed six runs (five earned) on 10 hits (one homer) while walking two and striking out 13 in 12 innings over his three starts (two with Triple-A Norfolk). He was able to throw 51 of his 78 pitches on Easter Sunday for strikes, and he could only need one more minor-league tune-up before the Orioles are ready to have him join the big-league roster. When he joins Baltimore's rotation, he'll be an innings-eater for those in AL-only fantasy leagues at the very least.

Seattle Mariners right-hander George Kirby (shoulder), who has been away from the team for almost a full month due to right-shoulder inflammation that caused him to be shut down in early March, is scheduled to face hitters for the first time in a live batting practice at T-Mobile Park this week, a source told MLB.com's Daniel Kramer. The 27-year-old has thrown multiple bullpen sessions at the team's spring training facility in Arizona but is now ready to face live hitters. When Kirby began throwing on March 21, he was hopeful for a late-April return, but now it's looking like he won't make his 2025 season debut until May or June. Until then, the M's expect to continue using right-hander Emerson Hancock in their starting rotation. Fantasy managers need to continue being patient with Kirby and keep him stashed in an injured-list spot in all formats.
