Triple-A Columbus placed Walters on its 7-day injured list Monday due to an unspecified injury.

After failing to win a spot in the Guardians' Opening Day bullpen coming out of spring training, Walters had gotten off to a strong start to the season with Columbus, producing a 1.35 ERA, 1.20 WHIP and 13:5 K:BB in 6.2 innings over seven appearances. However, the right-hander sustained an apparent injury during his most recent appearance Wednesday, temporarily halting any momentum he might have built for a promotion to the big leagues.

The Red Sox will option Kelly to Triple-A Worcester prior to Tuesday's game against the Mariners, Chris Cotillo of MassLive.com reports.

The transaction will clear a spot on the active roster for Brayan Bello (shoulder), who is slated to make his season debut. Kelly boasts an 11:2 K:BB over 10 innings this season but has also surrendered 10 runs across his seven appearances.

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.

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.

Hanifee (1-0) tossed two scoreless innings of relief to earn the win Monday against the Padres. He allowed one hit and struck out two.

After recording his first hold of the season in his last appearance Saturday, Hanifee notched his first win of the year Monday. The righty allowed an earned run in each of his first two 2025 outings, but since then, he's rattled off eight straight appearances without allowing any earned runs. Overall, Hanifee has a strong 1.54 ERA across 11.2 innings out of Detroit's bullpen.

Vest picked up the save in Monday's 6-4 win against the Padres, pitching a clean inning with one strikeout.

After both Tommy Kahnle (18 pitches) and Tyler Holton (28 pitches) appeared in Sunday's loss, Vest was called upon to polish off this win. The 29-year-old righty performed admirably, setting down the side in order on 10 pitches, nine of which were strikes. While Kahnle and Holton are the best candidates for saves in the Detroit bullpen, the closer situation is far from settled. Vest, with his stellar 0.93 ERA and 0.62 WHIP across 9.2 innings, is likely to see save opportunities here and there throughout the season.

Smith collected the save in Monday's 6-4 victory over the Yankees, pitching a scoreless inning while allowing one hit and no walks. He struck out two.

Smith neatly retired the side on 11 pitches, which included nine strikes. The 25-year-old completed the feat in style, striking out Aaron Judge swinging to end the game. Smith earned the save chance because Emmanuel Clase had pitched on three consecutive days prior to Monday. Despite the Cleveland closer's unsightly 7.84 ERA over 10.1 innings, Smith will likely remain in a setup role for the time being.
