Moll (shoulder) will begin a rehab assignment with Triple-A Louisville on Tuesday, Gordon Wittenmyer of The Cincinnati Enquirer reports.

Moll has been shelved since mid-April with a left shoulder impingement but has been cleared to test things out in a game setting. He is eligible for activation Saturday, and, given that his absence has been relatively brief, he should have a good shot to return at that time.

Atlanta optioned Petersen to Triple-A Gwinnett on Tuesday.

Petersen's stay with the big club lasted all of one day, with the right-hander not getting called upon in relief in Monday's 7-6 win over the Cardinals. He'll cede his spot on the 26-man active roster to right-hander Nathan Wiles, who was called up from Triple-A and is expected to work in bulk relief during Tuesday's game.

Atlanta released Willingham (undisclosed) on Tuesday.

A waiver pickup from Washington in January, Willingham failed to win a spot in Atlanta's Opening Day bullpen and began the season at Triple-A Gwinnett. He made two relief appearances and gave up one earned run on six hits and three walks while striking out five over 4.2 innings before landing on Gwinnett's 7-day injured list April 4. Atlanta hasn't shed light on the nature of Willingham's injury, but he'll now be moved off the 40-man roster as the big club looks to clear a spot for right-hander Nathan Wiles, whose contract was selected from Gwinnett in a corresponding move.

Diamondbacks manager Torey Lovullo said that Martinez was unavailable to pitch in Sunday's extra-innings win over the Cubs due to "fatigue" and a recent heavy workload, Jack Sommers of SI.com reports.

Martinez hadn't pitched since Thursday and threw only 10 pitches in that appearance, but trainers told Lovullo the reliever could use another day of rest Sunday. The Diamondbacks took the lead in the top of the 10th inning that day before Shelby Miller gave up the tying run in the bottom of the frame in his second inning of work. After Arizona grabbed the lead again with a run in the top of the 11th, Drey Jameson came on to secure his second career save. Martinez did not undergo any imaging and presumably will be available for Tuesday's series opener against the Rays. With A.J. Puk (elbow) out and Kevin Ginkel (shoulder) also still working his way back, Martinez is the clear favorite for saves in Arizona's bullpen right now.

Triple-A Scranton/Wilkes-Barre placed Arias on the 7-day injured list March 28.

The hard-throwing righty was dealt from the Cubs to the Yankees in exchange for cash in January after the Cubs had designated Arias for assignment. The days of Arias starting are over, but he had eight strikeouts and one walk in five one-inning spring training appearances and could develop into a high-leverage reliever in a couple years.

The Orioles placed Poteet on the 15-day injured list Tuesday with right shoulder inflammation.

Poteet was rocked for five runs while throwing 68 pitches over 2.2 innings in Sunday's blowout loss to the Reds and apparently came out of the appearance with a shoulder problem. It's not clear how long he might be sidelined.

White Sox manager Will Venable said that Wilson is in line to fill a bulk-relief role in Wednesday's game in Minnesota, Scott Merkin of MLB.com reports.

Wilson has worked exclusively out of the bullpen so far in 2025, but he's made 52 career starts in the majors, including nine last season with Milwaukee. The right-hander isn't stretched out enough to handle a traditional starting role, but he should be able to offer the White Sox a decent amount of length out of the bullpen after having previously covered three innings and 64 pitches in an April 4 relief appearance in Detroit. If Wilson excels in his appearance Wednesday, he could be in line for a more permanent spot in the White Sox rotation with Martin Perez (elbow) recently landing on the 60-day injured list.

Diaz allowed three runs on three hits and one walk over 1.1 innings in Monday's 6-3 loss to Miami. He also hit a batter.

Diaz stranded a pair of inherited runners to get out of the sixth inning but ran into trouble in the seventh, when pinch hitter Kyle Stowers took him deep for a three-run home run. It was the first time in four outings that Diaz was scored upon. The former closer has allowed four hits and four walks while striking two over four innings.

Sewald allowed two runs on two hits while striking out one over 1.1 innings in Monday's 6-4 win over the Yankees.

Sewald got the last two outs of the seventh inning before getting stung by a Jazz Chisholm two-run blast in the eighth. He's allowed three home runs and has a 6.10 ERA over 10.1 innings (12 outings). Sewald, who has experience as a closer, could nevertheless garner save opportunities at some point if the issues Emmanuel Clase (two blown saves, 7.84 ERA, 2.23 WHIP) has exhibited thus far prompts manager Stephen Vogt to try someone else in the role, at least temporarily.

Cantillo walked one and struck out one over a scoreless one-third of an inning in Monday's 6-4 win over the Yankees.

A day after recording his first MLB save, Cantillo was credited with his first hold when he finished out the eighth inning. The 25-year-old lefty began the season as a multi-inning reliever but has not worked more than one inning over the last four appearances. Cantillo has allowed just two earned runs while striking out 15 over 11.2 innings.
