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 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 Mariners signed Dunning to a minor-league contract Thursday, Chris Cotillo of MassLive.com reports.

Dunning had to settle for a minor-league deal after posting a 6.97 ERA and 21:7 K:BB over 20.2 innings between Texas and Atlanta in 2025. The 31-year-old could be useful swingman depth for Seattle at Triple-A Tacoma.

The Twins signed Rogers to a one-year, $2 million contract, Aaron Gleeman of The Athletic report.

Rogers was drafted by the Twins and spent the first six of his 10 big-league seasons in Minnesota. The left-hander split his time between the Reds and Cubs in 2025, finishing with a 3.38 ERA and 53:23 K:BB over 50.2 regular-season innings. The 35-year-old Rogers isn't as effective as he once was, but he could be part of the late-inning mix in an unsettled Twins bullpen.

Bickford signed a minor-league contract with the Tigers on Tuesday, Evan Woodbery of MLive.com reports.

Bickford spent time with the Cubs' and Phillies' Triple-A affiliates in 2025, posting a 3.38 ERA and 0.98 WHIP to go with a 54:17 K:BB across 48 total innings. The 30-year-old righty will likely spend the majority of 2026 at Triple-A Toledo but could return to the big leagues if he continues to find success in the minors.

The Rangers re-signed Sborz (shoulder) to a minor-league contract Tuesday that includes an invitation to spring training.

After being non-tendered by the Rangers in November, Sborz is now back in the fold on a minor-league deal. The 32-year-old missed much of the 2025 season while recuperating from shoulder surgery and was eventually shut down in September due to poor velocity and results during his rehab assignment. It's unclear whether Sborz will have any restrictions at the beginning of spring training.

Junis and the Rangers agreed on a one-year, $4 million contract Sunday, Ken Rosenthal of The Athletic reports.

Junis will head to Texas after posting a solid 2.97 ERA and 1.23 WHIP with 55 strikeouts over 66.2 innings in 57 regular-season appearances out of the bullpen with the Guardians in 2025. The Rangers will be the right-hander's fifth team in the last four seasons, and he'll provide his new squad with another experienced option in the bullpen ahead of the 2026 campaign.

Castro (knee) signed a minor-league contract with the Angels on Thursday, Jon Heyman of the New York Post reports.

Castro made six appearances with the White Sox last year, and he allowed five runs on five hits and five walks while striking out four batters over six innings before suffering a season-ending knee injury in late May. It's unclear where he currently stands in his recovery, but once healthy, the 31-year-old reliever will provide organizational depth at Triple-A Salt Lake and could make a handful of appearances for the Halos over the course of the season.
