The Mariners selected Lawrence's contract from Triple-A Tacoma on Wednesday.

Lawrence had made two starts with Tacoma this season, allowing five runs with an 8:3 K:BB over 10.1 innings. The veteran righty will give Seattle some length in the bullpen for now, but he could get a look as the club's No. 5 starter if Luis F. Castillo is unable to hold down a back-end rotation spot while George Kirby (shoulder) remains on the injured list.

The Mariners designated Hahn for assignment Wednesday.

Hahn gave up only one unearned run over four innings during his brief time with the big club, but he nonetheless has been jettisoned from the 26-man active roster and 40-man roster. Seattle selected the contract of Casey Lawrence from Triple-A Tacoma to replace Hahn.

The Orioles recalled Selby from Triple-A Norfolk on Wednesday.

Selby has made 26 appearances at the big-league level over the previous two seasons, collecting a 7.55 ERA and 35:19 K:BB over 31 frames. The right-hander tossed three scoreless innings in his first three outings with Norfolk and will provide manager Brandon Hyde with a fresh bullpen arm.

The Tigers announced Wednesday that Guenther, who was placed on Triple-A Toledo's 7-day injured list March 28 due to lumbar spine inflammation, is scheduled to throw a bullpen session Friday, Cody Stavenhagen of The Athletic reports.

Detroit optioned Guenther to Triple-A on March 17 after he failed to secure a spot in the Opening Day bullpen, but he wasn't known to be dealing with an injury until Toledo deactivated him to begin the season. While the fact that he's in line to step back on the mound Friday suggests he's making progress in his recovery, the reliever probably won't be ready to make his season debut for Toledo until late April at the soonest.

Mattison (elbow) will throw a live batting practice session Wednesday, Chris McCosky of The Detroit News reports.

Mattison is ready to face hitters as he continues to work his way back from Tommy John surgery. The 25-year-old has yet to pitch in the majors, but he's on the 40-man roster and could be an option for the Tigers' bullpen by June or so.

Vanasco (hip) will begin a rehab assignment with Single-A Lakeland on Wednesday, Chris McCosky of The Detroit News reports.

Vanasco has been working his way back from offseason hip surgery but is finally ready to pitch in games. The right-hander is not on the 40-man roster and will eventually be assigned to Triple-A Toledo, where he'll provide relief depth.

Yankees manager Aaron Boone said Wednesday that Matzek (oblique) will need "at least a few" more rehab appearances in the minors before being considered an option for the big-league bullpen, Gary Phillips of the New York Daily News reports.

Matzek isn't a member of the Yankees' 40-man roster and currently resides on Triple-A Scranton/Wilkes-Barre's 7-day injured list after he suffered an oblique strain in spring training while attending big-league camp as a non-roster invitee. The veteran southpaw made his first rehab appearance with Single-A Tampa on Sunday, striking out two while allowing one earned run on two hits in one inning. He'll likely make additional appearances with Tampa before eventually reporting to Triple-A, but he may not stick around with Scranton/Wilkes-Barre throughout the season. His minor-league contract contains a clause that would allow him to opt out and become a free agent May 1 if the Yankees don't promote him to the big leagues by then.

Clevinger (0-2) took the loss Tuesday against the Guardians after allowing a run on one hit and three walks in just one-third of an inning.

Clevinger came on in relief of Tyler Gilbert with two outs in the eighth and got to the ninth unscathed. However, the Guardians opened up the ninth with an infield single and Clevinger proceeded to eventually walk in the winning run after issuing three consecutive free passes. He has walked five batters and recorded two outs in his last two appearances and likely will find himself in some lower-leverage situations for the time being.

Clase (2-0) got the win over the White Sox on Tuesday after tossing a perfect ninth while recording two strikeouts.

Clase made quick work of the White Sox in the ninth, sending them down in order on nine pitches. He wound up with his second win of the early campaign after the Guardians walked it off in the bottom of the inning. Tuesday was Clase's first appearance in 2025 with multiple strikeouts, though he is still waiting to pick up his first save of the season.

Hurter picked up the save in Tuesday's 5-0 win over the Yankees, tossing three scoreless innings while allowing two hits and a walk. He struck out three.

Hurter entered in the seventh protecting a 5-0 lead and went on to blank the Yankees for another three innings. He now has two three-inning saves in his last two appearances, though those came over a week apart. Hurter owns a 3.68 ERA, 0.95 WHIP and 6:1 K:BB in 7.1 innings so far this season.
