Kimbrel signed a minor-league contract with the Mets that includes an invitation to spring training, Jon Heyman of the New York Post reports.

Kimbrel spent time with Atlanta and Houston in 2025, appearing in 14 MLB games and posting a 2.25 ERA, a 1.42 WHIP and a 17:7 KBB across 12 innings. Entering his age-38 season, Kimbrel will get an opportunity with the Mets, but he may need a strong showing during spring training in order to earn a place on the Opening Day roster.

Coleman signed a minor-league contract with the Yankees on Jan. 17.

Coleman made 11 appearances in the Orioles' minor-league system last season, posting a 4.91 ERA and 1.84 WHIP over 14.2 innings between Double-A and Triple-A before being released in mid-May. He'll get a chance to bounce back with the Yankees but doesn't project as anything more than organizational depth.

The Mariners designated Diaz for assignment Friday, Adam Jude of The Seattle Times reports.

With Cooper Criswell coming over from the Mets in a trade, Diaz will give up his place on the Mariners' 40-man roster. The 29-year-old southpaw made just one appearance with the Mariners near the start of the 2025 regular season, allowing one hit and striking out one batter over 1.1 innings. He spent the rest of the season at Triple-A Tacoma and turned in a 4.15 ERA and 1.32 WHIP across 138.2 frames.

The Mets traded Criswell to the Mariners on Friday in exchange for cash, Jorge Castillo of ESPN.com reports.

The 29-year-old was DFA'd by the Mets on Wednesday following the team's acquisition of Freddy Peralta and Tobias Myers, but Criswell will recapture a 40-man spot upon moving to Seattle. He posted a 3.57 ERA and 1.58 WHIP in 17.2 regular-season innings with the Red Sox in 2025 and will compete for a spot in the Mariners' bullpen during spring training.

The Yankees designated Ort (elbow) for assignment Friday.

The transaction clears a spot on the 40-man roster for waiver claim Michael Siani. Ort was a waiver claim himself earlier this month, and because he has the ability to refuse an outright assignment, his stint in the Yankees organization will likely be ending soon. The righty reliever posted a 4.89 ERA and 49:27 K:BB over 46 innings with the Astros in 2025 and missed the final month of the season with elbow inflammation.

The Reds signed Misiewicz to a minor-league contract Friday that includes an invitation to spring training.

Misiewicz made five appearances for the Twins this past season, yielding five runs with a 5:4 K:BB over 4.2 frames. The bulk of his year was spent at Triple-A St. Paul, where he held a 3.82 ERA and 30:11 K:BB across 33 innings. Misiewicz will compete for a bullpen job in Cincinnati, but the southpaw is likely ticketed for the Triple-A Louisville bullpen.

The White Sox signed Dominguez to a two-year, $20 million contract Friday, Jeff Passan of ESPN.com reports.

There's also a mutual option for 2028, per Joel Sherman of the New York Post, and the White Sox plan to use Dominguez as their closer. The right-hander has some modest closing experience, having notched 40 saves in his career, including 11 in 2024 between the Phillies and Orioles. The 31-year-old is coming off a 2025 campaign that saw him collect a 3.16 ERA and 79:36 K:BB over 62.2 regular-season frames between the Orioles and Blue Jays. Dominguez boasts a career 27.9 percent strikeout rate, but free passes (career 10.5 percent walk rate) have been a problem. With Dominguez taking over the ninth inning, previous incumbent closer options Jordan Leasure and Grant Taylor will work earlier in games with a rotation job potentially still in Taylor's future.

The Phillies re-signed Mayza to a minor-league contract Friday that includes an invitation to spring training.

Mayza finished last season with the Phillies, putting up a 3.78 ERA and 15:5 K:BB over 16.2 regular-season frames between Pittsburgh and Philadelphia. The veteran left-hander will compete for a spot in the Opening Day bullpen, but with Jose Alvarado and Tanner Banks locks for the roster and Kyle Backhus also around, Mayza is a good bet to begin the year at Triple-A Lehigh Valley.

Acton was designated for assignment by the Rockies on Thursday, Patrick Lyons of JustBaseball.com reports.

The Rockies made their signing of Willi Castro official, meaning they needed to make room on their 40-man roster. Acton was on the wrong end of that roster shuffle, as he lost his roster spot only about three months after he was claimed by the team. He made one appearance in the majors in 2025, firing a scoreless inning for the Rays.

Lovelady was designated for assignment Thursday, Max Goodman of NJ.com reports.

Lovelady re-signed with the Mets in October after closing the 2025 season with the team. He'll likely rejoin the 40-man roster at some point during the 2026 campaign as a depth option out of the bullpen, assuming he clears waivers.
