The Athletics outrighted Muller to Triple-A Las Vegas on Friday, Martin Gallegos of MLB.com reports.

Because he's been outrighted before, Muller has the option to elect free agency. The left-hander made 21 appearances for the A's in 2024 in relief, posting a 4.01 ERA and 36:10 K:BB across 49.1 frames.

Stratton (forearm) exercised his $4.5 million player option for the 2025 season Thursday, Mark Feinsand of MLB.com reports.

Stratton threw 58.1 innings out of the bullpen for the Royals in 2024, occasionally working in high-leverage situations. He posted a 5.55 ERA and 1.47 WHIP to go along with four saves and five holds. Stratton's season ended in mid-September due to forearm injury, though he is expected to be ready for the start of spring training.

Adams (forearm) cleared waivers Thursday and was sent outright to Triple-A Las Vegas.

Adams turned in a 3.92 ERA and 1.48 WHIP across 41.1 innings in 2024, but forearm tendinitis kept him out of action since mid-August. It's unclear if the 33-year-old will be ready for the start of spring training, but he'll now have to re-earn a spot on the 40-man roster once healthy.

The Rangers claimed Contreras off waivers from the Angels on Thursday, Kiley McDaniel of ESPN.com reports.

Contreras looked in 2022 like he might be part of the Pirates' rotation for a while, but he's collected a 5.47 ERA and 111:63 K:BB over 136.2 innings since the start of the 2023 season and is now in his third organization since May. The righty mostly pitched in relief in 2024, but the Rangers could stretch him back out during spring training.

Weaver was saddled with a blown save Wednesday against the Dodgers in Game 5 of the World Series, letting two inherited runners score while permitting one hit and one walk over 1.1 frames.

He was put into an impossible situation, taking over for Tommy Kahnle in the top of the eighth inning after Kahnle had loaded the bases with no one out. Weaver didn't permit a hit or a walk in the frame, but a pair of sac flies turned a one-run Yankees lead to a one-run deficit. He returned for the ninth inning and was pulled with one out and two runners on before Mark Leiter came on to escape the jam. The Yankees have a $2.5 million club option on Weaver for 2025, which they will undoubtedly pick up. He could open next season as the club's closer after finishing this year in the role.

Hartlieb signed a minor-league deal with the Yankees on Saturday.

Hartlieb got extended looks in the majors in 2019 and 2020, but he has since pitched primarily in the minors. He'll have a chance to serve as bullpen depth for the Yankees in 2025.

Fulmer was outrighted to Triple-A Salt Lake on Thursday.

Fulmer appeared in 37 games with the Angels in 2024 and posted a 4.15 ERA and 1.40 WHIP. Because he has been outrighted multiple times, he could opt for free agency and seek a new opportunity heading into 2025.

Marte (shoulder) was activated from the injured list and outrighted to Triple-A Salt Lake on Thursday.

Marte underwent surgery on his right shoulder in mid-September and is presumably still recovering. He could be ready to throw by spring training, though no official timeline has been announced by the team.

Wantz (elbow) was activated from the injured list and outrighted to Triple-A Salt Lake on Thursday.

Wantz underwent a procedure on his elbow in mid-July, but it was not Tommy John surgery. Nevertheless, he was unable to return to the mound in 2024 after experiencing a setback. He'll presumably be ready for the start of spring training, which would roughly be in line with his initial recovery timetable.

Leiter has been added to the Yankees' ALCS roster, Chris Kirschner of The Athletic reports.

Leiter is the injury replacement for Ian Hamilton (calf). The 33-year-old Leiter held a 4.98 ERA over 21.2 innings after being acquired by the Yankees at the trade deadline, while he struck out 33 and tallied 86 strikeouts across 58 frames in 2024 between his time with the Cubs and Yankees.
