The Astros designated Kessinger for assignment Monday, Chandler Rome of The Athletic reports.

The move clears a spot on the 40-man roster for the signing of Christian Walker, which was made official Monday. Kessinger, 27, is 8-for-61 at the plate over the last two seasons in the majors and has a career .694 OPS in the minors, but it's possible he'll draw interest from a team in need of utility infielder depth.

The Rangers designated Huff for assignment Monday, Kennedi Landry of MLB.com reports.

Huff has put up a .768 OPS with 10 home runs in 214 career plate appearances in the majors, albeit with a 33.6 percent strikeout rate. He never really got an extended look at the major-league level, but Huff should draw some interest via trade or waivers, especially if a team believes he can be capable enough defensively at catcher.

The Red Sox signed Davis to a minor-league contract Saturday.

Davis broke the news himself on his Instagram account. The right-hander holds a 7.71 ERA and 43:23 K:BB over 51.1 innings covering parts of three seasons at the major-league level. Davis has experience as a starter and reliever and it's not clear what role Boston has planned for him, but he'll likely begin the 2025 season at Triple-A Worcester.

The Rays signed Jimenez to a minor-league contract Monday that includes an invitation to spring training, Jesse Rogers of ESPN.com reports.

Per Hector Gomez of Z101Digital.com, Jimenez will earn $2 million if he makes the Opening Day roster, with an additional $2 million bonus waiting if he gets to 500 at-bats. Jimenez, 28, slashed only .238/.289/.336 with six home runs over 98 games between the White Sox and Orioles in 2024. He's reached 100 games played just twice in his career and hasn't hit 20 home runs since his rookie season back in 2019. Jimenez did still have a 49 percent hard-hit rate this past season and represents a no-risk, moderate-upside play for the Rays on a minor-league deal.

The Red Sox signed Buehler to a one-year, $21.05 million contract Monday, Russell Dorsey of Yahoo Sports reports.

The salary matches this year's qualifying offer total, with Buehler having the ability to make more in incentives. Buehler held a 5.38 ERA over 16 regular-season starts in his first full season back from Tommy John surgery and has thrown just 140.1 innings over the last three seasons combined. The 30-year-old will attempt to re-establish his value in 2025 before re-entering the market next winter.

The Rangers signed Pederson to a two-year, $37 million contract Monday, Buster Olney of ESPN reports.

The deal has an opt out after the first year. Pederson is coming off arguably the best offensive season of his career, having slashed .275/.393/.515 with 23 home runs over 132 contests. The left-handed hitting Pederson didn't make a single start against a traditional left-handed starter, and while the Rangers might not be quite as strict as the Diamondbacks were, the overwhelming majority of the 32-year-old's playing time should come at designated hitter versus righties.

The Nationals traded Garcia to the Rangers on Sunday in exchange for Nathaniel Lowe, Jeff Passan of ESPN.com reports.

Garcia appeared in 72 regular-season games for the Nationals in 2024 and finished with a 4.22 ERA, 1.19 WHIP and 75:16 K:BB across 59.2 innings while notching 13 holds. Garcia gives the Rangers a high-leverage, left-handed option out of the bullpen for the 2025 campaign.

The Red Sox signed Adams (forearm) to a minor-league deal Sunday with an invitation to spring training, Ari Alexander of KPRC 2 Houston reports.

Adams ended the 2024 regular season on the 15-day injured list due to right forearm tendinitis. He appeared in 56 games for the Athletics prior to the injury and registered a 3.92 ERA, 1.48 WHIP and 53:23 K:BB over 41.1 innings. The 33-year-old right-hander has a chance to earn a regular spot in the Red Sox's rotation once he is fully healthy.

The White Sox designated Julks for assignment Saturday.

Julks' departure from the 40-man roster opens up a spot for Cam Booser, whom Chicago acquired via trade earlier Saturday. Julks appeared in 66 games for the White Sox in 2024, slashing .214/.275/.306 with three homers and five stolen bases.

The Guardians signed Santana to a one-year, $12 million contract Saturday, Jeff Passan of ESPN.com reports.

Santana's signing came shortly after Cleveland traded Josh Naylor to Arizona for pitcher Slade Cecconi, so Santana appears set to take over as the starter at first base for the Guardians. The $12 million contract represents a nice pay raise for the veteran slugger, who joined Minnesota on a one-year, $5.25 million dollar deal last February and enjoyed a solid campaign with a .748 OPS -- his highest since 2019 -- while slugging 23 homers and notching 71 RBI over 594 plate appearances during the regular season. Santana is nearing the end of his career -- he'll turn 39 years old in April -- but should provide a decent amount of run production in the middle of Cleveland's lineup while serving as a bridge to the team's future.
