McGough signed a two-year minor-league contract with the Mets on Thursday, Will Sammon of The Athletic reports.

McGough made seven appearances (one start) with the White Sox's Triple-A affiliate during 2025, posting a 9.00 ERA and 2.20 WHIP over 15 innings before announcing his retirement in May. Now committed to playing again, the 27-year-old will look to get back on track with the Mets and likely begin the season at Triple-A Syracuse.

The Reds designated Zulueta for assignment Thursday.

The move frees up a 40-man roster spot for the addition of Pierce Johnson, whose signing was made official Thursday. Zulueta has made 19 relief appearances over the last two seasons with the Reds, collecting a 5.32 ERA and 25:11 K:BB across 23.2 frames. The righty will turn 28 next week and stands a good chance of passing through waivers unclaimed.

Padres manager Craig Stammen said Tuesday on Foul Territory that Musgrove (elbow) will not have a strict innings limit in 2026.

Musgrove missed the entire 2025 season while recovering from Tommy John surgery but has been throwing bullpen sessions since August. Stammen noted that while the Padres will keep a close eye on how Musgrove is feeling after each start, the team will take the righty "as far as he's willing to go" with his workload. After topping 180 innings in 2021 and 2022, Musgrove threw 97.1 innings in 2023 and 99.2 innings in 2024. It would be a big ask for the 33-year-old to get back to the 180-inning plateau in 2026, but it sounds like the Padres would allow him to get to that level as long as he feels good.

Atlanta designated Waldichuk for assignment Saturday.

Just two days after being claimed off waivers from the Athletics on Thursday, Waldichuk will once again enter the waiver process following Atlanta's addition of Tyler Kinley on Saturday. After missing the entire 2024 campaign while recovering from Tommy John surgery, the 28-year-old Waldichuk returned to action at Triple-A last season but struggled with an 8.65 ERA and 2.06 WHIP across 51 innings.

The Rockies traded Grosz to the Diamondbacks on Saturday in exchange for Jake McCarthy

Grosz spent all of 2025 at the High-A level, posting a 4.67 ERA and 1.30 WHIP across 125.1 innings between the Yankees' and Rockies' affiliates. The 23-year-old righty will likely aim to reach Double-A at some point in 2026.

Nelson and the Diamondbacks agreed to a one-year, $3 million contract to avoid arbitration Thursday, Jack Sommers of DBacks on SI.com reports.

Nelson was arbitration eligible for the first time and is set for a $2.2 million raise from last season. He posted career-best results in 2025 and is poised to be a key member of Arizona's rotation for the upcoming campaign.

Cabrera agreed to a one-year, $4.45 million contract with the Cubs on Thursday to avoid arbitration, Jesse Rogers of ESPN.com reports.

Cabrera put together a strong 2025 campaign with Miami, finishing with an 8-7 record (26 starts) while posting a 3.53 ERA, 1.23 WHIP and 150:48 K:BB across 137.2 innings. He was traded by the Marlins to the Cubs on Wednesday, and if healthy, he provides the Cubs with upside and strikeout potential out of the rotation.

Sears signed a one-year contract with the Padres on Thursday to avoid arbitration.

Sears was a regular part of the Athletics' rotation before being shipped to the Padres in late July, after which point he was sent back and forth between Triple-A and the majors. He ended the 2025 regular season with a 5.04 ERA and 1.32 WHIP -- both career worsts -- across 135.2 innings, and his spot in the Padres' rotation could be shaky if he gets off to a slow start in 2026.

Miller signed a one-year, $4 million contract with the Padres on Thursday to avoid arbitration.

It's a nice raise for Miller in his first season of arbitration eligibility. The right-hander opened 2025 with the Athletics before being traded to the Padres in July, and between both teams he posted a 2.63 ERA, 0.91 WHIP, 10 holds, 22 saves (out of 26 opportunities) and a 104:28 K:BB across 61.2 regular-season innings. Miller served as more of a setup man for the Padres after being the Athletics' top closer. However, with Robert Suarez signing with Atlanta during the offseason, Miller figures to step in as San Diego's closer for the 2026 campaign.

Meyer (hip) and the Marlins agreed to a one-year contract to avoid arbitration Thursday, Isaac Azout of FishOnFirst.com reports.

Meyer has struggled with injuries throughout his big-league career and made only 12 starts in 2025. He posted a 4.73 ERA and 68:20 K:BB across 64.2 frames before being sidelined in early July by a hip issue that required surgery. Meyer figures to be ready for spring training and should have the inside track on a rotation spot to begin 2026.
