Darvish (elbow) said Monday that he's unsure whether he will continue his baseball career after completing rehab for his November UCL repair with an internal brace and flexor tendon surgery, Dennis Lin of The Athletic reports.

Darvish will miss the entire 2026 season and will be 40 years old heading into the 2027 campaign. He's owed $30 million between 2027 and 2028, so while he has financial incentive to continue pitching, the right-hander is currently focused on his rehab and will make a decision about his playing career at a later date. Darvish posted a 5.38 ERA and 68:19 K:BB over 72 regular-season innings covering 15 starts for the Padres in 2025.

The Mets are considering using Sproat as a multi-inning reliever in 2026, Will Sammon of The Athletic reports.

The Mets still view Sproat as a starting pitcher over the long haul, but there's currently not room for him in the major-league rotation and the club believes he can help in the bullpen. Sproat made four starts for the Mets in September, finishing with a 4.79 ERA and 17:7 K:BB over 20.2 innings. The 25-year-old posted a 4.24 ERA and 113:53 K:BB across 121 frames in 2025 with Triple-A Syracuse.

The Diamondbacks signed Campbell to a minor-league contract Dec. 5.

In parts of three seasons in the majors, Campbell has collected a 5.65 ERA and 42:16 K:BB over 43 innings. The 28-year-old reliever will give the Diamondbacks some experienced bullpen depth at Triple-A Reno in 2026.

The Phillies signed Garcia to a one-year, $10 million contract Monday, Francys Romero of BeisbolFR.com reports.

The Phillies are expected to trade or release Nick Castellanos this offseason, and Garcia is now lined up to replace him in right field. Garcia has just a .675 OPS and 89 wRC+ over the last two seasons, though he graded out as a solid defender in right field in 2025. He should benefit from a ballpark and lineup upgrade in 2026 in what will be his age-33 season.

The Twins signed Bell to a one-year contract with a mutual option for 2027 on Monday, Jeff Passan of ESPN.com reports.

It's the first major-league free-agent signing this offseason for the Twins. Bell should see most of the playing time at first base in Minnesota but is also an option for starts at designated hitter. The 33-year-old slashed .237/.325/.417 with 22 home runs across 140 games this past season for the Nationals.

Elko (knee) agreed to a minor-league contract with the White Sox on Sunday, Jack Ankony of SI.com reports.

The 26-year-old hit the opening market in November after Chicago elected not to tender him a contract for 2026, but he's now back with the organization on a minor-league deal. Elko underwent surgery to repair a torn ACL in his right knee after the season, so he'll be unavailable for at least the first few months of the 2026 campaign.

Brewers GM Matt Arnold said Sunday that the organization is open to utilizing Zerpa as a starting pitcher, Adam McCalvy of MLB.com reports.

The left-hander was acquired from the Royals in exchange for Isaac Collins and Nick Mears, and the Brewers apparently view Zerpa as more than a relief option. The 26-year-old came up through the minors as a starter but operated as a reliever the past two years for the Royals, making all but two of his 129 regular-season appearances out of the bullpen. Even if he sticks as a starter and is fully stretched out to begin the season, Zerpa could have a short leash given his limited workload the last few years.

Kelly agreed to a two-year, $40 million contract with the Diamondbacks on Sunday, Ken Rosenthal of The Athletic reports.

The 37-year-old right-hander was dealt by the Diamondbacks to the Rangers at the trade deadline in July, and he'll now return to the desert for an eighth season. Kelly should step back in as Arizona's ace after posting a 3.52 ERA, 1.11 WHIP and 167:48 K:BB across 184 innings last season.

The Brewers traded Mears to the Royals on Saturday alongside Isaac Collins in exchange for Angel Zerpa, Jeff Passan of ESPN.com reports.

Mears enjoyed the best campaign of his career with Milwaukee in 2025, finishing the regular season with a 3.49 ERA and 0.97 WHIP over 56.2 innings while also notching his first career save. The 29-year-old righty is unlikely to beat out Carlos Estevez and Lucas Erceg in the race for high-leverage opportunities, but Mears will provide some depth into Kansas City's middle-relief unit.

The Brewers traded Collins to the Royals on Saturday alongside Nick Mears in exchange for Angel Zerpa, Jeff Passan of ESPN.com reports.

Collins entered the 2025 season as a relatively unknown player but quickly proved himself as a productive bat, slashing .263/.368/.411 with 54 RBI, 56 runs scored and 16 stolen bases over 441 regular-season plate appearances. However, he struggled down the stretch and didn't have a significant role for the Brewers in the playoffs. His overall performance allowed him to take fourth place in NL Rookie of the Year voting. With Garrett Mitchell (shoulder) expected to return in 2026 and Akil Baddoo signing with the Brewers on Thursday, Milwaukee's outfield room was beginning to become crowded, so the team will now send Collins to Kansas City, where the 28-year-old outfielder should have a much easier path to regular playing time.
