The Marlins re-signed Navarreto to a minor-league contract Monday.

Navarreto elected free agency last month after being outrighted off the Marlins' 40-man roster, but he's found his way back into the organization. The 30-year-old got into eight games with Miami in 2025, going 4-for-14 with one home run. Navarreto is likely pegged for Triple-A Jacksonville to begin the 2026 campaign.

The Giants designated Wiemer for assignment Wednesday, Alex Pavlovic of NBC Sports Bay Area reports.

After being DFA'd by the Marlins in November and landing in San Francisco via trade, Wiemer will now go through the waiver process for the second time in as many months. His subtraction from the 40-man roster will create room for Jason Foley, who signed with the Giants on Tuesday.

The Cardinals designated Koperniak for assignment Wednesday, Jeff Jones of the Belleville News-Democrat reports.

Koperniak will lose his 40-man roster spot in order to make room for Dustin May, who officially signed with St. Louis on Wednesday. Koperniak, 27, spent all of 2025 at Triple-A Memphis and endured his worst minor-league season yet, slashing .249/.322/.387 across 537 plate appearances.

The Mets designated Waddell for assignment Wednesday.

The move clears a spot on the 40-man roster for Drew Romo, who was claimed off waivers. Waddell had re-signed with the Mets last month after proving useful in a swingman role in 2025, holding a 3.45 ERA and 22:11 K:BB over 31.1 innings. If he clears waivers, Waddell would have the ability to elect free agency.

The Mets claimed Romo off waivers from the Orioles on Wednesday.

Romo has bounced around from the Rockies to the Orioles and now the Mets this month. The switch-hitting catcher is just 9-for-54 at the plate during his brief time in the majors. With Francisco Alvarez and Luis Torrens slated to open 2026 as the Mets' catching duo, Romo is likely to begin the 2026 campaign at Triple-A Syracuse.

The Padres signed Hunt to a minor-league contract Tuesday.

Hunt spent the 2025 season at Triple-A Tacoma in the Mariners organization, slashing .272/.368/.452 with eight home runs in 68 contests. The 27-year-old was up in the big leagues briefly with the Orioles in 2024 but is still looking to make his major-league debut. Hunt was originally selected by the Padres in the second round of the 2017 First-Year Player Draft before being traded to the Rays in the Blake Snell deal.

Donovan said Tuesday that he is "full go" in his offseason workouts following Oct. 7 abdominal surgery, Derrick Goold of the St. Louis Post-Dispatch reports.

Donovan played through an injury to his abdominal wall for much of the second half before getting shut down late in the year and then having surgery. His offseason workouts are no longer restricted and he will arrive at spring training 100 percent. What team Donovan reports to in February remains to be seen, as he's widely expected to be traded this offseason. The Giants and Mariners reportedly are leading a pack of interested teams to land the super utility player.

Garabito signed a minor-league contract with the Brewers on Wednesday that includes an invitation to spring training, Adam McCalvy of MLB.com reports.

Garabito finished the 2025 season with the Samsung Lions of the Korea Baseball Organization, holding a 2.64 ERA and 84:37 K:BB over 78.1 innings covering 15 starts. The 30-year-old has made 21 appearances (two starts) at the big-league level, producing a 5.77 ERA. Garabito is likely to begin the 2026 season in the rotation at Triple-A Nashville.

The Mets signed Weaver to a two-year, $22 million contract Wednesday, Anthony DiComo of MLB.com reports.

Weaver becomes the second former Yankees reliever to sign with the Mets this offseason, joining closer Devin Williams. The 32-year-old Weaver struggled at times during the second half in 2025, but he finished his tenure in pinstripes with a 3.22 ERA and 191:49 K:BB across 162 regular-season innings. Weaver will help set up for Williams with the Mets.

The Phillies signed Keller to a two-year, $22 million contract Wednesday, Matt Gelb of The Athletic reports.

Keller was a full-time reliever for the first time in 2025 with the Cubs and excelled, collecting a 2.07 ERA, 0.96 WHIP and 75:22 K:BB over 69.2 regular-season innings. The Phillies intend to keep him in a bullpen role, though his past starting experience allows for the possibility that he could make some starts, if needed. Keller is in line to help set up for closer Jhoan Duran.
