The Rockies signed Bellozo to a minor-league contract Monday, Francys Romero of BeisbolFR.com reports.

Bellozo elected free agency back in November after being removed from the Marlins' 40-man roster. The right-hander held a 4.65 ERA and 1.33 WHIP across 81.1 innings in 2025. Bellozo will likely begin the 2026 season at Triple-A Albuquerque as swingman depth.

The Rays acquired Williamson from the Mariners on Monday as part of a three-team trade involving the Cardinals, Adam Jude of The Seattle Times reports.

Brendan Donovan is headed to Seattle as part of the deal. Williamson is a glove-first third baseman who slashed just .253/.294/.310 with one homer in 85 regular-season games for the Mariners in 2025. He is now stuck behind Junior Caminero in Tampa Bay, so Williamson could begin the 2026 campaign at Triple-A Durham.

The Mariners acquired Donovan from the Cardinals on Monday as part of a three-team deal involving the Rays, Katie Woo of The Athletic reports.

The Cardinals will receive Jurrangelo Cijntje and Tai Peete from the Mariners and Colton Ledbetter and a compensatory draft pick from the Rays. Ben Williamson will go to Tampa Bay. Second base is Donovan's primary position, but he is also an option to see playing time at third base for Seattle and is a good bet to bat leadoff. Donovan slashed .287/.353/.422 with 10 homers over 118 contests for the Cardinals in 2025 and is under team control through the 2027 campaign.

Mariners general manager Justin Hollander said Sunday that he expects Raley to start against most right-hander this season, Adam Jude of the Seattle Times reports.

Hollander does not anticipate a "hardcore platoon" in right field and designated hitter, but as a "baseline," he expects left-handed hitters Raley and Dominic Canzone to play against most righties and right-handed hitters Victor Robles and Rob Refsnyder to start versus most lefties. Raley collected a disappointing .202/.319/.311 batting line during the 2025 regular season, but he slashed .242/.333/.453 versus right-handers.

Mariners general manager Justin Hollander said Sunday that, "as a baseline," he expects Luke Raley and Dominic Canzone to start against right-handers and Rob Refsnyder and Robles to start versus lefties, Adam Jude of the Seattle Times reports.

Hollander does not believe the team will employ a "hardcore platoon" in right field and at designated hitter, but as a general rule, the left-handed hitting Raley and Canzone will start most days versus righties and the left-handed hitting Refsnyder and Robles will be in there against southpaws. Robles missed much of the 2025 season with a dislocated shoulder, and when healthy, he had just an 84 wRC+ in the regular season versus righties.

The Guardians re-signed Allard to a minor-league contract Monday that includes an invitation to spring training.

Allard elected free agency after being outrighted off the Guardians' 40-man roster back in November, but he's ultimately found his way back into the organization. The left-hander was effective as a multi-inning reliever in 2025, posting a 2.63 ERA and 1.20 WHIP to go along with a 42:14 K:BB across 65 regular-season frames. Allard will have to win a roster spot but could fill a long relief role again.

The Angels designated Laweryson for assignment Monday, Rhett Bollinger of MLB.com reports.

The transaction frees a spot on the 40-man roster for the re-signing of Yoan Moncada, which was officially announced Monday. Laweryson was a waiver claim of the Angels back in November after he yielded two runs (one earned) with a 7:0 K:BB over 7.2 frames covering five relief outings for the Twins in 2025. He could be appealing on waivers to teams in need of bullpen depth.

The Angels outrighted Meckler to Triple-A Salt Lake on Monday.

He's no longer on the 40-man roster, but Meckler will remain in the organization after passing through waivers unclaimed. The 25-year-old slashed .287/.390/.370 at Triple-A Sacramento in the Giants organization in 2025, though he hit just one home run across 87 games.

Waldrep could begin the season at Triple-A Gwinnett, Mark Bowman of MLB.com reports.

Waldrep seemingly did enough last season to be locked into Atlanta's rotation, posting a 2.88 ERA, 1.19 WHIP and 55:22 K:BB over 56.1 innings covering nine starts and one extended relief outing. However, several other of the team's rotation candidates cannot be optioned to the minors, while Waldrep can, so the 23-year-old could be a roster casualty as Atlanta seeks to retain depth. Bowman writes that while Waldrep might wind up being the most valuable of the current fifth-starter candidates by the end of the season, if he becomes a "lasting part" of the rotation early on, "then something disastrous will have already happened." Atlanta has Chris Sale and Spencer Strider locked into rotation spots, with Spencer Schwellenbach (elbow), Reynaldo Lopez (shoulder) and Grant Holmes (elbow) expected to fill the other slots, if healthy. Bryce Elder, Joey Wentz, Martin Perez (shoulder) and Waldrep are among the club's depth starters, and Waldrep is the only one in the group that has minor-league options remaining. Atlanta also remains in the market for additional rotation help, which could push Waldrep farther down the pecking order.

Ryan (elbow) said Saturday that he added 30 pounds over the offseason in hopes of increasing his durability, Fabian Ardaya of The Athletic reports.

Ryan believes his relatively slight build contributed to the Tommy John surgery that knocked him out for the entirety of the 2025 season. While rehabbing that injury, Ryan "ate a lot of calories" and "lifted like an animal," which resulted in his weight going from 195 to 225. Ryan said he's had a normal offseason, having already thrown 10 bullpen sessions and touched triple digits on the radar run. The 27-year-old is unlikely to be on the Dodgers' Opening Day roster, but he could be a key rotation depth piece. Ryan held a 1.33 ERA and 18:9 K:BB over 20.1 innings covering four starts for the Dodgers in 2024.
