Mata has signed a contract in Japan, Chris Henrique of BostonSportsJournal.com reports.

Mata struggled to a 5.48 ERA and 1.68 WHIP with 93 strikeouts over 67.1 innings with Triple-A Worcester, so he's elected to try his luck elsewhere in 2026. He played at Triple-A in 2022, 2023, 2024 and 2025 but was never tapped to make his big-league debut while in Boston's farm system.

Mets president of baseball operations David Stearns said Monday that Minter (lat) is questionable for Opening Day, Anthony DiComo of MLB.com reports.

Minter underwent season-ending left lat surgery in early May and it's unclear where exactly he is in the rehab process. Stearns noted that if Minter is not ready for Opening Day, his absence is expected to be brief. The southpaw exercised his $11 million player option for 2026 and is poised to fill a key setup role for the Mets, if healthy.

Padres manager Craig Stammen said Monday that Morejon will remain in the bullpen next season, Alden Gonzalez of ESPN.com reports.

Morejon has past starting experience and the Padres had considered moving him into their rotation in 2026. However, it's been decided to keep the lefty in a relief role instead. Morejon has posted a 2.42 ERA and 141:38 K:BB over 137.1 regular-season innings as a full-time reliever since the start of the 2024 campaign. The Padres are also keeping Mason Miller in a relief role, so Morejon likely won't see many, if any, save chances unless Miller gets injured.

The Padres signed Acosta to a one-year contract Monday.

Acosta has never pitched in the big leagues but received a major-league deal from the Padres after holding a 2.42 ERA and 72:27 K:BB over 52 innings across three minor-league levels in the Nationals organization in 2025. The 27-year-old has minor-league options remaining and will likely begin the 2026 season at Triple-A El Paso.

Angels general manager Perry Minasian said Monday that Silseth will be used as a reliever in 2026, Jeff Fletcher of the Orange County Register reports.

All 10 of Silseth's appearances for the Angels in 2025 came out of the bullpen, and 11 of his 18 outings at Triple-A Salt Lake were in relief. The 25-year-old is out of minor-league options and will likely begin next season in a middle relief capacity.

The Angels could turn to Joyce (elbow) as their closer during the 2026 season, Jeff Fletcher of the Orange County Register reports.

General manager Perry Minasian indicated Monday that he's undecided whether the team needs to add an established closer from outside the organization. If it doesn't, Joyce and Robert Stephenson (elbow) appear to be the top in-house candidates for the role. Both pitchers, however, are coming off injuries, with Joyce missing most of 2025 following surgery to repair the labrum in his right shoulder. It's unclear where Joyce is currently at in his throwing program, and it's also not a given that his stuff will return to what it was pre-surgery, making him an iffy guy to count on for 2026.

Stephenson (elbow) could get an opportunity to serve as the Angels' closer next season, Jeff Fletcher of the Orange County Register reports.

General manager Perry Minasian said Monday that the team is undecided whether it will add an established closer to replace free agent Kenley Jansen. As things stand right now, Stephenson and Ben Joyce (shoulder) appear to be the top in-house candidates for the role. Stephenson missed the entire 2024 season following UCL reconstruction with an internal brace, and he was limited to just 12 appearances for the Angels and eight rehab outings in 2025 because of more arm issues. The righty finished this past season on the injured list with right elbow inflammation, and it's unclear whether he's been able to have a normal offseason throwing program. Stephenson is owed $11 million in 2026 and the Angels have a $2.5 million option on him for 2027 that vested after he needed UCL surgery.

The Mets signed Edwards to a minor-league contract with an invitation to spring training Monday, Will Sammon of The Athletic reports.

The Mets plan to stretch Edwards out to use him as rotation depth at Triple-A Syracuse, per Sammon and Ken Rosenthal of The Athletic. Edwards made four appearances between the Angels and Rangers in 2025, allowing three runs over six innings. The 34-year-old hasn't spent a significant amount of time in the majors since 2023, when he posted a 3.69 ERA over 32 outings with the Nationals.

The Diamondbacks signed Soroka to a one-year contract Monday, Jesse Rogers of ESPN.com report.

The deal is worth $7.5 million, with $2 million more possible in incentives, per Nick Piecoro of The Arizona Republic. Soroka -- who will slot into the Arizona rotation -- flashed some encouraging signs in 2025, ultimately finishing with a 4.52 ERA, 1.13 WHIP and 95:29 K:BB over 89.2 regular-season innings covering 17 starts and five relief appearances between the Nationals and Cubs. He missed much of the second half with a shoulder injury but returned late in the season in a relief role. Soroka is a poor bet to hold up health-wise given that he hasn't reached 100 innings at the big-league level since 2019, but he has some upside and will only cost Arizona a one-year commitment.

The Nationals traded Ferrer to the Mariners on Saturday in exchange for Harry Ford and minor-league pitcher Isaac Lyon, Robert Murray of FanSided.com reports.

Ferrer finished the 2025 season with a 4.48 ERA and 1.27 WHIP over 76.1 innings, and he also recorded 11 saves upon taking over as the Nationals' closer following the departure of Kyle Finnegan. The Mariners' bullpen is a bit deeper than Washington's, however, so Ferrer is likely to take on a middle-relief role with his new club.
