Samaniego was traded along with Johan Oviedo and Adonys Guzman from the Pirates to the Red Sox in exchange for Jhostynxon Garcia and Jesus Travieso on Thursday, Jeff Passan of ESPN.com reports.

The Pirates added Samaniego to the 40-man roster in mid-November, but he'll now try to reach the majors with the Red Sox. He'll be entering his age-27 season and has yet to pitch above Double-A, though he did post a strong 3.08 ERA and 0.92 WHIP across 26.1 innings with Altoona while working exclusively as a reliever. Samaniego is a strong candidate to begin the 2026 season with Triple-A Worcester, but he could provide depth to the Boston bullpen at some point in 2026.

The Padres signed Adcock to a one-year contract Thursday.

Adcock got into three games with the Mets in 2025 but spent most of the season at Triple-A Syracuse, where he posted a 4.66 ERA and 35:14 K:BB over 36.2 frames. The right-handed reliever does not have minor-league options remaining and has previously been outrighted, so he'll either be part of the Padres' Opening Day bullpen or have a chance to return to the open market.

The Phillies re-signed Mercado to a minor-league contract Nov. 24.

Mercado was non-tendered by the Phillies but quickly re-signed to a minor-league pact. The 26-year-old has had a rough go of it at the major-league level thus far, allowing 21 runs and a whopping 10 home runs over 16 innings.

The Twins signed Hartwig to a minor-league contract with an invitation to spring training Thursday, Darren Wolfson of Channel 5 Saint Paul reports.

Hartwig split the 2025 season between Triple-A Syracuse in the Mets organization and with the Hanshin Tigers of Nippon Professional Baseball in Japan. Slated to turn 28 later this month, Hartwig has collected a 5.14 ERA and 34:19 K:BB over 42 innings during his time at the big-league level.

Pagan signed a two-year, $20 million contract with the Reds on Wednesday, Ken Rosenthal of The Athletic reports.

Pagan thrived as the Reds' primary closer this past season, posting a 2.88 ERA and 0.92 WHIP alongside an 81:22 K:BB across 68.2 innings while converting a career-high 32 saves during the regular season. Assuming the Reds don't make another move for a high-leverage reliever, the 31-year-old righty will presumably maintain his hold on ninth-inning duties for Cincinnati.

The Guardians signed Brogdon to a one-year, $900,000 contract Wednesday, Zack Meisel of The Athletic reports.

Brogdon made 43 appearances for the Angels in 2025, putting up a 5.55 ERA and 49:18 K:BB over 47 innings. Slated to turn 31 next month, Brogdon hasn't had much success at the big-league level since 2022, but the Guardians felt the right-handed reliever was worthy of a major-league deal. Brogdon will have an additional year of arbitration eligibility in 2027.

The Diamondbacks re-signed Henry (elbow) to a minor-league contract with an invitation to spring training Monday.

Henry was non-tendered by Arizona last month, but the two sides have reunited on a minor-league pact. The left-hander missed much of 2025 due to injury and could be out for all of next season following Tommy John surgery in June. Henry holds a career 5.07 ERA over 37 appearances (32 starts) at the big-league level.

Jax, Garrett Cleavinger and Edwin Uceta are expected to be part of a closer-by-committee for the Rays in 2026, Marc Topkin of the Tampa Bay Times reports.

There's been some talk of Jax potentially stretching out to join the Rays' rotation, but the current plan is to leave the 31-year-old in the bullpen. Acquired from the Twins at the trade deadline, Jax had an elevated 4.23 ERA in 2025, but a 2.51 FIP and 35 percent strikeout rate were more indicative of how he pitched. Mason Montgomery, Bryan Baker, Hunter Bigge, Steven Wilson and Manuel Rodriguez (elbow) could also work their way into high-leverage work, but the tentative plan seems to be for Jax, Cleavinger and Uceta to share the closer role.

Uceta, Garrett Cleavinger and Griffin Jax are expected to be part of a closer-by-committee for the Rays next season, Marc Topkin of the Tampa Bay Times reports.

Pete Fairbanks easily paced the Rays with 27 saves in 2025, but he is a free agent after the team declined his $11 million option. That leaves a vacancy in the ninth inning, and it seems the Rays plan to fill that void with multiple arms. Uceta finished with a 3.79 ERA in 2025, but he had a 32.1 percent strikeout rate and boasts a 33.3 percent strikeout rate in his two seasons with Tampa Bay.

Cleavinger, Griffin Jax and Edwin Uceta are expected to be part of a closer-by-committee for the Rays in 2026, Marc Topkin of the Tampa Bay Times reports.

The Rays elected to decline Pete Fairbanks' $11 million option, and the plan for now is to fill that ninth-inning vacancy with multiple players. Cleavinger had the best season of his career in 2025, holding a 2.35 ERA and 82:18 K:BB over 61.1 innings. The lefty has neutral splits, so he should not be at a matchup disadvantage when it comes to who manager Kevin Cash chooses to deploy in save situations.
