Hader earned a save against the Tigers on Monday, allowing one hit and striking out two batters in a scoreless inning of work.

Hader inherited a three-run lead in the ninth frame and went right after each batter he faced, throwing 12 of his 14 total pitches for strikes. The veteran closer did give up a two-out double, but that proved to be a minor inconvenience as Hader wrapped up his eighth save in eight chances. After posting a disappointing 3.80 ERA last season, Hader has been dominant so far in 2025, allowing just one run on seven hits while registering a 19:3 K:BB over 14 innings covering 12 appearances.

Athletics manager Mark Kotsay said that Lopez will start Tuesday's game against the Rangers, Jessica Kleinschmidt of Baseball America reports.

Lopez has worked out of the bullpen in all three of his appearances with the Athletics and hasn't recorded more than five outs on any occasion, but he had been getting stretched out as a starter at Triple-A Las Vegas before being recalled Saturday. The lefty covered five innings in both of his most recent two appearances and delivered his best outing yet prior to his promotion, striking out 10 batters and allowing no runs on four hits and two walks in an April 12 contest. Lopez could end up getting multiple turns through the big-league rotation while J.T. Ginn (elbow) is on the shelf.

Miller issued a walk in a scoreless inning and earned a save against Texas on Monday. He struck out one batter.

Miller put Marcus Semien on base with a four-pitch walk to begin the ninth inning but avoided any danger and closed out the 2-1 win. Miller has now converted all nine of his save chances this season. He's delivered two straight scoreless appearances after coughing up two runs against the White Sox on Friday. Miller owns a terrific 22:2 K:BB with a 1.64 ERA through 11 innings.

Bautista struck out two batters in a perfect inning and earned a save against the Yankees on Monday.

Bautista threw eight of 14 pitches for strikes and had no trouble retiring the Yankees' 1-2-3 batters to close out the 4-3 win. He's earned a save in three straight appearances and has converted all four of his chances this season. Bautista's six-inning scoreless streak has dropped his ERA to 2.25 with a 10:6 K:BB through eight frames.

Sewald left Monday's game against the Twins due to right shoulder inflammation, Chris Assenheimer of the Elyria Chronicle-Telegram reports.

Sewald was lifted from Monday's appearance after retiring a pair of Minnesota batters, and further evaluation revealed inflammation in his throwing shoulder. The team will presumably wait to see how he feels Tuesday and could send him for additional scans before making a decision on whether a trip to the injured list is necessary.

Sewald (undisclosed) was forced to exit Monday's contest against the Twins in the top of the fifth inning, Chris Assenheimer of the Elyria Chronicle-Telegram reports.

Sewald entered the game in the top of the fifth with the Guardians trailing 4-0, subsequently retiring the first two batters he faced, one of which he struck out. The right hander then delivered a first-pitch 90.7 mph fastball to Ryan Jeffers, which missed the zone. Sewald then appeared to be in some discomfort, exiting the game with one of Cleveland's trainers. Tim Herrin replaced him on the mound and more information on Sewald's status will likely come following Monday's contest.

The Rangers designated Robert for assignment Monday.

The transaction frees up a spot on the 40-man roster for Dane Dunning, whose contract was selected Monday. Robert got into four games with the Rangers last season but has spent all of the 2025 campaign at Triple-A Round Rock, where he's allowed four runs (two earned) with a 17:4 K:BB over 11.2 innings.

Yankees manager Aaron Boone said Monday that Effross (hamstring) will throw live batting practice soon, Gary Phillips of the New York Daily News reports.

Out since late February with a Grade 2 hamstring strain, Effross began a throwing program in early April and is ready to progress to facing hitters. He should be ready for a rehab assignment soon, although there's no timetable for the reliever's return to the Yankees' bullpen.

The Orioles claimed Pennington off waivers from the Rangers on Monday, Jake Rill of MLB.com reports.

Pennington hasn't pitched this season, but he isn't dealing with an injury and was instead working on his mechanics with Triple-A Round Rock before the Rangers designated him for assignment last week, per Jacob Calvin Meyer of The Baltimore Sun. Pennington will occupy a spot on the Orioles' 40-man roster and will report to Triple-A Norfolk to begin his time in the organization.

The Rangers optioned Boushley to Triple-A Round Rock on Monday, Shawn McFarland of The Dallas Morning News reports.

Boushley has permitted five runs with a 6:2 K:BB over 7.2 innings covering three appearances this season in the majors. Dane Dunning will absorb his spot on the roster and in the bullpen.
