Miller earned a save against the Rockies on Saturday, allowing one hit and striking out two batters over one scoreless inning.

Miller had a relatively easy time preserving a three-run lead -- he gave up a one-out infield single but needed just 13 pitches to retire the side. The save was the second in as many days and third overall for the flamethrowing righty, who has yet to give up a run through four innings this season. He's been as dominant as ever with an 8:1 K:BB and just two hits allowed over that span.

Zeferjahn (hamstring) is likely unavailable Saturday against the Guardians, Rhett Bollinger of MLB.com reports.

Zeferjahn was removed from Friday's game with the hamstring issue. The exact timeline for his return remains unclear, though the Angels' bullpen looks likely to be shorthanded again Saturday.

Newcomb is scheduled to start for Boston in Game 1 of Sunday's doubleheader against St. Louis, Ian Browne of MLB.com reports.

Saturday's matchup was postponed due to inclement weather, and the two teams will consequently play a twin bill Sunday. Newcomb is scheduled to oppose Andre Pallante in the opener, and the Red Sox have yet to announce their starter for the nightcap. Newcomb struggled in his first start of the campaign, allowing four runs on eight hits and two walks while striking out four batters over four innings in a loss to Baltimore on March 31.

The Mariners optioned Saucedo to Triple-A Tacoma on Saturday.

Saucedo has gotten off to a rough start this season, with four earned runs allowed in just 2.2 innings spanning three appearances. He'll look to right the ship in the minors; meanwhile, Jesse Hahn will come up from Triple-A to fill the vacancy in Seattle's bullpen.

The Mariners selected Hahn's contract from Triple-A Tacoma on Saturday.

Hahn hasn't appeared in a major-league game since 2021 during his time with the Royals, but he's now set to join Seattle's big-league squad to provide some bullpen depth. Tayler Saucedo was optioned to Tacoma to make room on the Mariners' roster, and Cody Bolton was DFA'd to free up a 40-man spot.

Manager Aaron Boone said Saturday that Effross (hamstring) has resumed his throwing program, Gary Phillips of the New York Daily News reports.

Boone added that he's not sure what stage Effross is at in his recovery, though the fact that he's back to throwing again after suffering a setback is encouraging. The right-hander has been out since late February with a Grade 2 hamstring strain and is likely still several weeks from returning.

Loaisiga (elbow) threw a bullpen session at Double-A Somerset on Saturday, Bryan Hoch of MLB.com reports.

Loaisiga still has more boxes to check off in his rehab from UCL reconstruction surgery before he can begin a rehab assignment. However, he aims to return to the Yankees' bullpen by late May or early June, which manager Aaron Boone says is a realistic timeline.

Marsh suffered a minor setback while rehabbing his injured right shoulder at the team's complex in Arizona, Anne Rogers of MLB.com reports.

The Royals are going to shut Marsh down for 7-to-10 days before re-evaluating him, which will obviously delay when he makes his season debut. The 26-year-old righty didn't have a defined return timeline prior to his setback, though we might finally receive one once he's been cleared to restart his throwing program.

Clase allowed two runs on three hits over one inning in Friday's 8-6 win over the Angels.

Clase entered in a non-save situation and was tagged for a pair of runs, including a solo home run. It's unclear why manager Stephen Vogt used his closer, other than the manager perhaps wanting to make sure the Guardians ended a three-game losing streak. Clase, who allowed just five runs over 74.1 innings in 2024, has already ceded three through four innings in 2025.

Maeda allowed three runs on four hits and a walk in an inning of relief during Friday's 7-4 win over the White Sox. He struck out one.

Maeda entered the contest in the eighth inning with the Tigers up 7-1, and he made it through his first frame unscathed. However, the righty struggled mightily in the ninth and was yanked without recording any outs. Maeda has only made two appearances so far this year, but he's allowed five runs already over three innings of work. It's an uninspiring start to his relief role, though he does have time to turn things around.
