The Orioles claimed Walker off waivers from Atlanta on Wednesday, Roch Kubatko of MASNSports.com reports.

Walker went from Baltimore to Atlanta via waiver claim less than a month ago, and he'll now head back to the Orioles. The left-hander holds a career 6.59 ERA and 31:14 K:BB over 27.1 innings covering parts of three big-league seasons. Walker does not have minor-league options remaining.

Adam (quadriceps) is expected to be ready to throw off a mound sometime during spring training, Kevin Acee of the San Diego Union-Tribune reports.

Adam underwent surgery in September to repair a torn left quad tendon. While it seems a stint on the injured list to begin the 2026 season is likely, Adam might not need to miss much time. The 34-year-old boasts a 1.66 ERA and 101:32 K:BB over 92 regular-season innings during his time with the Padres.

Herget will enter spring training as a starting pitcher, Ken Rosenthal and Will Sammon of The Athletic report.

Herget was a starting pitcher in college but has not made a traditional start in his entire professional career. He did, however, record more than three outs in 31 of his 59 appearances for the Rockies in 2025. Herget was excellent out of the Rockies' bullpen last season, posting a 2.48 ERA and 81:26 K:BB over 83.1 innings.

Reynolds signed a contract with the Yokohama Bay Stars on Tuesday, Jon Heyman of the New York Post reports.

Reynolds was non-tendered by San Diego after he turned in a 5.33 ERA and 1.37 WHIP over 27 regular-season innings in the majors. Rather than looking to rebound with another MLB organization, the 27-year-old righty will now take his talents to Japan in an effort to give new life to his career.

Finnegan signed a two-year, $19 million contract with the Tigers on Tuesday, Robert Murray of FanSided.com reports.

After turning in a 4.38 ERA and 1.28 WHIP over 39 innings with the Nationals, Finnegan became dominant on the mound once he moved from Washington to Detroit at the trade deadline, posting a 1.50 ERA and 0.72 WHIP with a 23:4 K:BB in 18 regular-season innings with the Tigers. He'll now officially stay put in the Motor City for the 2026 campaign and figures to remain in the mix for saves along with Will Vest.

Soto signed a one-year, $7.75 million contract with the Pirates on Tuesday, Jorge Castillo of ESPN.com reports.

Soto improved in nearly every major statistical category in 2025, finishing the regular season with a 4.18 ERA and 1.43 WHIP alongside 22 holds and a 70:24 K:BB over 60.1 innings between the Orioles and Mets. He'll receive a $2.4 million raise upon moving to the Pirates and is likely to remain in a high-leverage role; however, the majority of save opportunities will presumably continue going to Dennis Santana.

Cardinals president of baseball operations Chaim Bloom said Tuesday that Thompson (lat) should be ready for the start of spring training, Derrick Goold of the St. Louis Post-Dispatch reports.

Thompson missed the entirety of the 2025 season due to a left lat strain, encountering multiple setbacks along the way. He was removed from the Cardinals' 40-man roster last month, but the southpaw remains in the organization and will compete for a roster spot in spring training.

Atlanta manager Walt Weiss said Tuesday that Lopez (shoulder) will be stretched out as a starting pitcher during spring training, Mark Bowman of MLB.com reports.

Weiss noted that Lopez could eventually become a bullpen option if that's the route the team ultimately decides to take, but for the time being Lopez will prepare to be in Atlanta's 2026 rotation. The right-hander missed nearly the entire 2025 season following arthroscopic shoulder surgery in April, but he was throwing off a mound by September and should be ready for the start of spring training.

Dodgers general manager Brandon Gomes has said that Graterol (shoulder) will be "full-go" for spring training, Fabian Ardaya of The Athletic reports.

Graterol missed the entire 2025 season following November 2024 labrum surgery on his right shoulder. He experienced a setback with the shoulder during the second half, but it appears the hard-throwing reliever is back on track now. Graterol has hardly pitched the last two seasons because of injury, but he held a 1.20 ERA over 68 appearances in 2023, his last full season.

The Dodgers signed Diaz to a three-year, $69 million contract Tuesday, Jeff Passan of ESPN.com reports.

For the second straight offseason the Dodgers have inked the top closer on the free-agent market. The $23 million average annual value sets a new record for a reliever. Diaz will turn 32 in March but is coming off one of his best seasons, having collected a 1.63 ERA, 0.87 WHIP and 98:21 K:BB over 66.1 innings while notching 28 saves. He will take over as closer for the two-time defending World Series champs.
