Roa cleared waivers Thursday and was sent outright to Triple-A Jacksonville.

Roa pitched three scoreless innings for the Marlins this season but spent most of his time in Triple-A, where he posted a 2.83 ERA and 1.10 WHIP over 60.1 frames. Despite his strong performance, he'll now lose his place on Miami's 40-man roster and aim to earn it back during spring training.

The Red Sox activated Guerrero from the 60-day injured list and designated him for assignment Thursday, Chris Cotillo of MassLive.com reports.

Guerrero missed a significant chunk of the 2025 season with an elbow issue, but he's healthy now, having made four appearances in the Dominican winter league. The 25-year-old has an uninspiring 19:16 K:BB over 27.1 innings at the big-league level, but he has a 29.8 percent strikeout rate in the minors and has minor-league options remaining, so Guerrero could draw interest on waivers.

The Marlins claimed Brzykcy off waivers Thursday from the Nationals.

Brzykcy appeared in 26 games with the Nationals in 2025, posting a 9.00 ERA and a 24:12 K:BB across 23 innings. He closed out the season at Triple-A Rochester and logged a 17.18 ERA across 11 innings after being optioned there Aug. 5.

The Mariners claimed Loutos off waivers from the Washington Nationals on Thursday.

Loutos, a 26-year-old right-hander, made 12 MLB appearances during the 2025 season, split between stints with the Dodgers and Nationals. He posted a 12.75 ERA and a 2.33 WHIP with an 8:8 K:BB over 12 innings. He fared significantly better with the Nationals' Triple-A affiliate in Rochester, posting a 4.32 ERA and a 27:13 K:BB across 25 innings. He'll join the Mariners' 40-man roster.

The Dodgers exercised Vesia's (personal) $3.55 milion club option for 2026 on Thursday, Fabian Ardaya of The Athletic reports.

With a 3.02 ERA and 0.99 WHIP across 59.2 regular-season innings, Vesia played a crucial part in stabilizing a Dodgers bullpen that often struggled in 2025. He also gave up two earned runs over 4.2 innings in the postseason, but personal matters prevented him from pitching during the World Series. The left-hander is expected to take on a high-leverage role again in 2026.

Atlanta outrighted Payamps to Triple-A Gwinnett on Thursday.

Payamps has the ability to decline the outright assignment and elect free agency, which he seems likely to do. The 31-year-old reliever held a 6.84 ERA over 30 appearances between Milwaukee and Atlanta in 2025, but a 2.78 ERA over 137 regular-season appearances for the Brewers across 2023 and 2024 should be enough for a team to take a flier on the righty.

Atlanta outrighted Cox to Triple-A Gwinnett on Thursday.

Cox made 13 appearances for Atlanta in 2025, posting an 8.86 ERA and 22:7 K:BB over 21.1 innings. The lefty reliever is no longer on the 40-man roster but remains in the organization.

The Rockies claimed Acton off waivers from the Rays on Thursday.

Acton posted a 3.68 ERA and 1.13 WHIP across 58.2 innings at Triple-A Durham in 2025, which is evidently enough for the Rockies to feel comfortable adding him to a very weak pitching staff. Colorado's lack of depth gives the 27-year-old a decent chance to break spring training with the big club; otherwise, he'll report to Triple-A Albuquerque.

The Tigers declined Sewald's $10 million mutual option for 2026 on Thursday, Evan Petzold of the Detroit Free Press reports.

Sewald exercised his part of the option, but the Tigers declined their side and will pay the reliever a $1 million buyout instead. The 35-year-old Sewald was limited to only 19.2 regular-season innings in 2025 due to a shoulder issue, posting a 4.58 ERA and 20:6 K:BB between the Guardians and Tigers. He finished the season healthy, but Sewald didn't pitch during the wild-card series versus the Guardians and was not included on the Tigers' ALDS roster.

Criswell signed a one-year, $800,000 contract with the Red Sox on Thursday, Robert Murray of FanSided.com reports.

Criswell appeared in seven games for Boston in 2025, finishing the regular season with a 3.57 ERA and 1.58 WHIP through 17.2 innings. He put up similar numbers at Triple-A Worcester (3.70 ERA, 1.35 WHIP) before elbow inflammation put an early end to his season in late August. The 29-year-old righty doesn't have any more minor-league options remaining, so he will have to make the Red Sox's Opening Day roster to avoid losing his 40-man spot.
