Hader (biceps) threw a bullpen session Friday, Chandler Rome of The Athletic reports.

Hader's scheduled bullpen seemingly went as planned, which means the veteran lefty is still on schedule. Astros general manager Dana Brown said Thursday that Hader will begin facing hitters by mid-April, so he's still a ways away from returning.

Seattle recalled Wilcox from Triple-A Tacoma on Friday.

Wilcox, after initially falling short of the Opening Day roster, will join the big-league club after reliever Carlos Vargas (lat) was placed on the 15-day injured list. Wilcox has appeared in just one MLB game during his career.

The Mariners placed Vargas on the 15-day injured list Friday, retroactive to March 24, due to a right lat strain.

Vargas threw 77 innings of relief for the Mariners in 2025 and figured to play an important role out of the bullpen once again in 2026. However, his season debut will be pushed back at least two weeks as he tends to a strained lat. Cole Wilcox was called up from Triple-A Tacoma in a corresponding move.

The White Sox claimed Hudson off waivers from the Mets on Friday.

Hudson was designated for assignment Wednesday, and he'll return to the White Sox, with whom he spent the tail end of the 2025 campaign. The southpaw has no minor-league options remaining, so he'll claim a spot on the 26-man active roster. Hudson appeared in 16 MLB games last season between Chicago and Milwaukee, posting a 4.80 ERA and 19:13 K:BB across 15 innings.

Chapman picked up the save Thursday against the Reds, retiring all three batters he faced in the ninth inning.

Although Chapman failed to record a strikeout, he managed to keep the ball in the yard via three flyouts to nail down a save in his first appearance of the campaign. After posting a career-best 1.17 ERA and 0.70 WHIP over 67 regular-season appearances in 2025, the hard-throwing left-hander is locked in as Boston's top closer to begin the season.

Crochet (1-0) picked up the win Thursday against the Reds, allowing no runs on three hits and two walks in six innings. He struck out eight.

The All-Star southpaw found himself in midseason form in his season debut, firing six shutout frames and also notably escaping a bases-loaded jam to close his final frame. Crochet was also able to throw 80 pitches Thursday, and his final start during spring training saw him hurl 89 pitches. He should build up to closer to a full workload in his next start, which is slated to come in Houston next week.

Smith (0-1) took the loss Thursday against the Brewers, allowing four runs (three earned) on three hits and two walks while striking out two over 1.2 innings.

Smith cruised through a scoreless first inning before unraveling in the second, with the damage highlighted by a bases-clearing double from William Contreras. After laboring through 54 pitches and only recording five outs, Thursday marked the shortest outing of the right-hander's young career. After an All-Star rookie campaign in 2025 that saw him hold a 3.81 ERA with 145 strikeouts in 146.1 innings, Smith will look to move past this disastrous performance and return to his previous form in his next scheduled start, which tentatively lines up to come in Miami.

Rogers allowed one hit while striking out one over a scoreless inning in Thursday's 2-1 loss against Baltimore.

Rogers was used in the eighth inning in a game the Twins were trailing 2-1. It was a high-leverage situation, but Cole Sands was warming up in case the Twins tied the game or took the lead. Rogers may still figure into the closer mix, but manager Derek Shelton has said he's still figuring out his bullpen and roles will be determined by performance early in the season.

Jax blew the save Thursday against the Cardinals, allowing one run on one hit in two-thirds of an inning.

The Rays had mounted a 7-1 lead in the sixth inning before St. Louis came roaring back in the second half of the frame, and Jax was unable to put out the fire. The right-hander entered the year as one of Tampa Bay's favorites for saves, with Edwin Uceta (shoulder) on the injured list, but Thursday's effort won't do him many favors. That said, Garrett Cleavinger gave up two runs in one-third of an inning, so this closer committee appears to be very much unsettled.

Topa allowed one run on two hits with no walks or strikeouts over one inning in Thursday's 2-1 loss against the Orioles.

Topa was used in the seventh inning in a tied game in his first appearance. While he could be used in late-inning save situations at some point, his first usage of the season wouldn't seem to indicate he's at the top of the mix for save opportunities.
