Criswell earned the save in Sunday's 8-0 win over the Guardians, allowing two hits while striking out five over three scoreless innings.

Criswell was sharp Sunday, limiting the Guardians to a pair of singles to close out Seattle's shutout victory, earning his second career save. The 29-year-old Criswell made the team as a long-relief option after posting a 2.51 ERA across 14.1 innings in spring training. While he may have a defined role in the Mariners' bullpen, don't expect Criswell to be a frequent source of saves. The right-hander has a career ERA of 4.42 with a 1.42 WHIP across 158.2 major-league innings.

Abreu allowed one run on two walks in one-third of an inning during the Astros' 9-7 win over the Angels on Sunday.

Abreu was brought in for the top of the ninth inning to protect the Astros' three-run lead. However, he walked two of the three batters he faced and was replaced by Bryan King, and the former was tagged with a run on an RBI single from Nolan Schanuel. Abreu has yielded four earned runs on four walks and one hit across 1.1 innings to open the season, which isn't a great sign given that he was tabbed as the Astros' interim closer in the absence of Josh Hader (biceps). King could be thrust into closing situations if Abreu's early struggles continue.

Alexander earned a save after tossing one inning, allowing an unearned run on one hit and a hit-by-pitch while striking out a batter in Saturday's 5-4 extra-inning win over the Phillies.

Alexander was the next man up after Texas turned to Robert Garcia and Chris Martin in the ninth inning. Alexander hit Otto Kemp with an 84.8 mph cutter to open the frame before later surrendering a two-out single by Bryce Harper, which drove in the automatic runner from second base. The southpaw was then able to settle in and strand Kemp at third base to end the game by getting Alec Bohm to pop out for the final out. Alexander isn't necessarily in the mix quite yet for the closer's role, but he is the first Ranger to notch a save in 2026.

Joyce (shoulder) isn't yet tossing bullpens at full intensity, but he's doing well in his throwing program, per MLB.com.

Joyce continues to work toward returning to game action after undergoing right shoulder surgery last May. Angels manager Kurt Suzuki said the righty reliever looks good and may be able to make his return to game action before long. When Joyce is activated, he could quickly work his way up to a high-leverage role and potentially even closing duties.

Dominguez (0-1) blew his save opportunity and took the loss against the Brewers on Sunday. He allowed two runs on two hits and one walk in one-third of an inning.

The White Sox found themselves in trouble after loading the bases in the eighth inning, which prompted the team to bring in Dominguez to protect a three-run lead. He got the first batter he faced to pop out and was one out away from getting out of the frame unscathed. However, he proceeded to give up a two-run single to Luis Rengifo before yielding a three-run homer to Christian Yelich. It was a tough situation to get out of, but the White Sox signed Dominguez to a two-year, $20 million contract this past offseason to do just that.

Yates has been playing catch, and his injured left knee is improving, per MLB.com.

Yates landed on the IL on March 24 due to left knee inflammation. The Angels are planning to take a cautious approach to his return, so the fact that he's been able to do some throwing -- even just by playing catch -- is a positive sign. Yates' next step will likely be a bullpen session. Jordan Romano is the lead candidate to work as Los Angeles' closer for the time being, and there's no guarantee Yates will be the top ninth-inning option upon his return.

Acton was designated for assignment by the Marlins on Sunday, Jordan McPherson of the Miami Herald reports.

Acton is the odd man out on Miami's 40-man roster after the team acquired infielder Leo Jimenez from the Blue Jays on Sunday. Acton has tossed 2.1 scoreless frames, allowing one hit and one walk while striking out four batters in two appearances with Triple-A Jacksonville so far this season. The 27-year-old was claimed off waivers by Miami after the Rockies let him go in late January, and he will now be available to be claimed by the rest of the league once again.

Megill earned the save in the Brewers' 9-7 win over the White Sox on Sunday, allowing one hit while striking out two in a scoreless ninth inning.

The Brewers bats rallied with a six-run eighth inning, and Megill was brought out for the top of the ninth for his first save opportunity of the season. He yielded a single to Tristan Peters before striking out the next two batters, and Megill came away with the save after getting Miguel Vargas to fly out to right field. Megill is looking to build off a solid 2025 regular season in which he collected a career-high 30 saves (eighth most in the majors) while posting a 2.49 ERA, 1.13 WHIP and 60:17 K:BB across 47 innings.

Smith signed a minor-league contract with Minnesota on Sunday, Aaron Gleeman of The Athletic reports.

The 32-year-old righty owns a 3.48 ERA and 1.28 WHIP over 192 career appearances in the majors, but after missing the entire 2025 season while recovering from his second Tommy John surgery, he had to settle for a minor-league deal with the Nationals in free agency this winter. Smith was released after he was unable to win a spot in Washington's season-opening bullpen, but he quickly found work in a new organization. He's expected to report to Triple-A St. Paul and could be in the mix for a call-up quickly if he shows that he's regained his pre-surgery velocity and command.

Mlodzinski did not factor into the decision in Sunday's 4-3 extra-inning win over the Mets, allowing two runs on six hits and no walks with eight strikeouts over 4.1 innings.

Mlodzinski threw 55 of 85 pitches for strikes and generated just eight whiffs while mostly keeping the Mets in check. The 27-year-old posted a career-high 99 innings last season working as both a starter and reliever, so he likely won't go deep into games often early in 2026. He's slated for a home matchup against the Orioles next weekend.
