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

Zerpa finished the 2025 season with a 4.18 ERA and 1.38 WHIP across 64.2 innings while also recording 14 holds. The Brewers aren't hurting for high-leverage arms with Trevor Megill, Abner Uribe and Jared Koenig already making up the back end of their bullpen, so Zerpa will likely start out in a middle-relief role with his new club.

The Diamondbacks designated Jarvis for assignment Friday.

The transaction frees up a 40-man roster spot for Michael Soroka, whose signing was officially announced Friday. Jarvis has a 3.69 ERA over 105 innings at the major-league level, but that's come with an unappetizing 71:52 K:BB.

The Cubs signed Milner to a one-year, $3.75 million contract Thursday, Mark Feinsand of MLB.com reports.

Milner will be reunited with manager Craig Counsell, who he pitched for in three of his four years with the Brewers. The left-handed reliever spent the 2025 campaign with the Rangers, collecting a 3.84 ERA, 51.4 percent groundball rate and 58:21 K:BB over 70.1 frames.

Atlanta designated Rolison for assignment Thursday.

The transaction frees up a spot on the 40-man roster for the addition of Robert Suarez, who was signed to a three-year deal. Rolison was just acquired from Colorado for cash considerations last month after he had been removed from the Rockies' 40-man roster. He posted a 7.02 ERA and 25:20 K:BB over 42.1 innings in 2025.

Atlanta signed Suarez to a three-year, $45 million contract Thursday, Jeff Passan of ESPN.com reports.

Atlanta re-signed Raisel Iglesias to a one-year, $16 million contract earlier this offseason, but it wasn't done with high-leverage reliever additions. Ken Rosenthal of The Athletic says Iglesias will remain the team's closer for the upcoming season, with Suarez settling into a setup role. Suarez has put up a 2.87 ERA, 0.97 WHIP and 134:32 K:BB over 134.2 regular-season innings since the start of the 2024, collecting 76 saves along the way.

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.

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.
