The Athletics selected Watson with the sixth pick in the Rule 5 Draft on Wednesday and traded him to the Red Sox, per Chris Cotillo of MassLive.com.

A 28-year-old righty reliever from the Giants organization, Watson was originally drafted by the Orioles back in 2016 and he has never pitched in the big leagues. Last season, Watson logged a 4.26 ERA, 1.46 WHIP, 64 strikeouts, 16 walks and nine saves in 50.2 innings in the Pacific Coast League. The Red Sox will likely use the 6-foot-5 Watson in low-leverage situations if he makes the Opening Day roster.

The Pirates selected Baumler with the fifth pick in the Rule 5 Draft on Wednesday and traded him to the Rangers, per Evan Grant of The Dallas Morning News.

Baumler received a seven-figure bonus from the Orioles out of high school in 2020 but he has dealt with significant shoulder issues over the years. The 6-foot-2 righty touched 98 mph in 2025 while logging a 2.04 ERA, 1.08 WHIP and 46 strikeouts in 39.2 innings as a reliever, primarily at High-A. The Rangers will likely attempt to use Baumler as a low-leverage reliever in 2026 before potentially sending him back to the minors in 2027.

The Orioles claimed Walker off waivers from Atlanta on Wednesday, Roch Kubatko of MASNSports.com reports.

Walker went from Baltimore to Atlanta via waiver claim less than a month ago, and he'll now head back to the Orioles. The left-hander holds a career 6.59 ERA and 31:14 K:BB over 27.1 innings covering parts of three big-league seasons. Walker does not have minor-league options remaining.

Finnegan signed a two-year, $19 million contract with the Tigers on Tuesday, Robert Murray of FanSided.com reports.

After turning in a 4.38 ERA and 1.28 WHIP over 39 innings with the Nationals, Finnegan became dominant on the mound once he moved from Washington to Detroit at the trade deadline, posting a 1.50 ERA and 0.72 WHIP with a 23:4 K:BB in 18 regular-season innings with the Tigers. He'll now officially stay put in the Motor City for the 2026 campaign and figures to remain in the mix for saves along with Will Vest.

Matz agreed to a two-year contract with the Rays on Monday, Jon Heyman of the New York Post reports.

Matz will suit up for the sixth different team in his veteran career after coming to terms on what's believed to be a multi-year contract with Tampa Bay. The southpaw was used in a variety of scenarios during the 2025 campaign with Boston and St. Louis, which included him securing the first two saves of his big-league career along with five wins. He logged 76.2 innings across 53 appearances last season. It's unclear whether the Rays are planning to use Matz as a starter or reliever.

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 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.

VanWey cleared waivers Friday and was outrighted to Triple-A Sugar Land, Chandler Rome of The Athletic reports.

VanWey reached the majors for the first time in 2025 and logged a 5.06 ERA alongside a 1.69 WHIP over 10.2 innings. He now seems poised to begin the new season back in Triple-A, and the Astros could look to fill his spot on the 40-man roster during the Rule 5 Draft.
