Vargas signed a minor-league contract with the Diamondbacks on Friday, Jon Heyman of the New York Post reports.

Vargas spent most of his time at Triple-A Reno this past season but still managed to appear in 38 games for the D-backs, during which he slashed .270/.292/.383 with 19 RBI and 12 runs scored. He'll officially return to the organization to begin the 2026 campaign, although he's expected to remain an organizational depth piece.

The Pirates acquired Lowe, Jake Mangum and Mason Montgomery from the Rays on Friday in a three-team trade that sent Mike Burrows to the Astros and Jacob Melton and Anderson Brito to Tampa Bay, Chandler Rome and Ken Rosenthal of The Athletic report.

The Rays picked up Lowe's $11.5 million option for 2026 last month but will now ship him to another team. Lowe slashed .256/.307/.477 with 31 home runs over 134 games with the Rays during the 2025 season. The 31-year-old will give the Pirates some much-needed thump to their lineup and also take over at a position of need in second base.

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.

Polanco signed a two-year, $40 million contract with the Mets on Saturday, Will Sammon of The Athletic reports.

After posting a career-worst .651 OPS in 2024, Polanco rebounded to the tune of a .265/.326/.495 slash line while logging 26 homers, 78 RBI and 64 runs scored over 524 regular-season plate appearances in 2025. He'll now help bolster the Mets' offense, though he's unlikely to continue playing at the keystone, considering the team traded for Marcus Semien in November. New York may instead utilize Polanco mainly as a DH or shift him to first base to make up for the loss of Pete Alonso.

The Mets are considering using McNeil (shoulder) as the strong side of a platoon at first base next season, Tim Healey of The Boston Globe reports.

Healey says the club could consider signing Paul Goldschmidt as the short side of that platoon. It wouldn't make for a very exciting replacement for Pete Alonso, who agreed to a long-term contract with the Orioles on Wednesday, and the likelier scenario is still that McNeil is traded this winter. McNeil underwent thoracic outlet surgery after the season but is expected to be ready for spring training.

Rojas signed a one-year, $5.5 million contract with the Dodgers on Wednesday, Daniel Alvarez-Montes of ElExtraBase.com reports.

Rojas has previously stated his intentions to retire from professional baseball after the 2026 campaign, and he will officially remain in Dodger blue for what will be his 13th and final MLB season. The 36-year-old slashed .262/.318/.397 with 27 RBI and 35 runs scored across 317 regular-season plate appearances in 2025 and figures to retain his role as a utility infielder for Los Angeles.

Valdez (shoulder) has returned to game action with the Estrellas Orientales in the Dominican Winter League, Alex Stumpf of MLB.com reports.

Valdez underwent season-ending surgery in May to repair a dislocated left shoulder, but he's played three winter ball games and smacked a grand slam in his third contest for Estrellas on Sunday. Slated to turn 27 later this month, Valdez slashed .209/.294/.363 with two home runs and an 11:16 BB:K over 102 plate appearances for Pittsburgh before getting hurt. It seems Valdez will ready to roll for the start of spring training and he'll compete for a spot on the Pirates' Opening Day roster in 2026.

The Rangers are trading Semien to the Mets in exchange for outfielder Brandon Nimmo, Jeff Passan of ESPN.com reports.

Semien's numbers have been trending down in recent years, and his .669 OPS last season was the lowest mark of his career. However, the 35-year-old still provided a mix of moderate power and speed with 15 homers and 11 stolen bases, and he offers elite defense at second base, as he's coming off winning his second Gold Glove Award. Semien ended the campaign on the 60-day injured list due to a foot injury, but he's expected to have a normal offseason and to be ready for spring training. Nimmo has a full no-trade clause in his contract, but per Will Sammon of The Athletic, the outfielder has already approved the deal.

Atlanta and Dubon avoided arbitration by agreeing to a one-year contract Friday.

Jon Heyman of the New York Post says the deal is worth $6.1 million. Dubon was acquired via trade from the Astros earlier this week and is tentatively slated to open 2026 as Atlanta's starting shortstop. However, further roster additions could push the 31-year-old to a utility role.

The Astros traded Dubon to Atlanta on Wednesday in exchange for Nick Allen, Brian McTaggart of MLB.com reports.

Dubon slashed .241/.289/.355 with seven homers, 33 RBI and 43 runs scored across 398 plate appearances in 2025. While he may not be the most formidable threat at the plate, Dubon offers elite defensive versatility. He could see most of his action at shortstop if Atlanta doesn't make any significant offseason acquisitions.
