The Twins signed Hartwig to a minor-league contract Thursday, Michael Mayer of MetsmerizedOnline.com reports.

Hartwig split the 2025 season between Triple-A Syracuse in the Mets organization and with the Hanshin Tigers of Nippon Professional Baseball in Japan. Slated to turn 28 later this month, Hartwig has collected a 5.14 ERA and 34:19 K:BB over 42 innings during his time at the big-league level.

Conine will be given reps at first base during spring training, Ken Rosenthal and Patrick Mooney of The Athletic report.

Conine has not played anywhere other than the corner-outfield spots in pro ball, but the Marlins plan to give him a test run at first base. The position is wide open, so Conine could even start there if he adapts well to first base. Conine missed most of the 2025 season following surgery to repair a dislocated left shoulder, but he returned late in the year and enters the offseason healthy.

Pagan signed a two-year, $20 million contract with the Reds on Wednesday, Ken Rosenthal of The Athletic reports.

Pagan thrived as the Reds' primary closer this past season, posting a 2.88 ERA and 0.92 WHIP alongside an 81:22 K:BB across 68.2 innings while converting a career-high 32 saves. Assuming the Reds don't make another move for a high-leverage reliever, the 31-year-old righty will presumably maintain his hold on ninth-inning opportunities in Cincinnati.

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 infield depth for Los Angeles.

Mullins signed a one-year, $7 million contract with the Rays on Wednesday, Marc Topkin of the Tampa Bay Times reports.

2025 marked one of Mullins' worst seasons at the plate in the majors, as he finished the year with a .216/.299/.391 batting line over 498 plate appearances alongside 17 homers, 59 RBI, 58 runs scored and 22 steals. With fellow lefty-hitting outfielders Chandler Simpson, Jake Fraley and Josh Lowe already in Tampa Bay, Mullins may have a hard time securing an everyday role with the Rays.

The Guardians signed Brogdon to a one-year, $900,000 contract Wednesday, Zack Meisel of The Athletic reports.

Brogdon made 43 appearances for the Angels in 2025, putting up a 5.55 ERA and 49:18 K:BB over 47 innings. Slated to turn 31 next month, Brogdon hasn't had much success at the big-league level since 2022, but the Guardians felt the right-handed reliever was worthy of a major-league deal. Brogdon will have an additional year of arbitration eligibility in 2027.

The Astros signed Perez to a minor-league contract Nov. 28.

Perez spent all of the 2025 campaign at Triple-A Iowa in the Cubs organization, putting up a .944 OPS with 27 long balls. The 35-year-old last saw action at the big-league level in 2023 and will provide the Astros with experienced catching depth at Triple-A Sugar Land.

Atlanta signed Pope to a minor-league contract Nov. 30.

Pope made his major-league debut in 2025 with one scoreless appearance for the Diamondbacks before electing free agency last month after he was removed from the 40-man roster. The 27-year-old held a 4.60 ERA and 34:10 K:BB across 29.1 frames with Triple-A Reno and will likely begin the 2026 season at Triple-A Gwinnett.

The Diamondbacks re-signed Henry (elbow) to a minor-league contract Monday.

Henry was non-tendered by Arizona last month, but the two sides have reunited on a minor-league pact. The left-hander missed much of 2025 due to injury and could be out for all of next season following Tommy John surgery in June. Henry holds a career 5.07 ERA over 37 appearances (32 starts) at the big-league level.

Arroyo will begin transitioning from second base to left field this month during the Columbian Winter League, Adam Jude of the Seattle Times reports.

Arroyo played second base exclusively in 2025 between High-A Everett and Double-A Arkansas, slashing .262/.401/.433 with 17 homers and 12 steals between the two stops. He has never played the outfield before, but with the Mariners' infield depth, the organization has elected to move the 21-year-old to left field. Arroyo could push to debut at some point during the 2026 season.
