The Mets claimed Criswell off waivers from the Red Sox on Friday, Jorge Castillo of ESPN.com reports.

Criswell had been designated for assignment following Boston's five-player trade with Pittsburgh on Thursday. The 29-year-old has been a useful swingman for the Red Sox the last two seasons, holding a 4.00 ERA and 82:36 K:BB over 117 innings covering 19 starts and 14 relief appearances. Criswell does not have minor-league options remaining but is not yet arbitration-eligible, so the Mets will have several years of control of the righty.

The Diamondbacks re-signed Rashi to a minor-league contract with an invitation to spring training Friday.

Arizona non-tendered Rashi last month, but he'll return to the organization. Slated to turn 30 in January, Rashi posted a 4.41 ERA and 22:8 K:BB across 16.1 innings with the Diamondbacks in 2025.

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.

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 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.

Atlanta signed Young (elbow) to a one-year contract Tuesday.

It's a split contract for Young, who will miss at least the first half of the 2026 season while recovering from Tommy John surgery. The left-handed reliever holds a career 4.01 ERA and 78:25 K:BB over 60.2 innings covering parts of four major-league seasons, which includes stints in Atlanta in 2022 and 2023.

Williams agreed to a three-year contract with the Mets on Monday, Will Sammon of The Athletic reports.

Williams will remain in New York but is headed to Queens following Monday's signing. The 31-year-old had his fair share of struggles with the Yankees during the 2025 campaign, ending the year with four blown saves in 22 chances and ultimately losing his grip on the closer's role. He finished the regular season with a 4.79 ERA and 1.13 WHIP with a 90:25 K:BB across 62.0 frames. Williams will receive a fresh start with the Mets on a deal that will guarantee him more than $50 million, per Jeff Passan of ESPN.com.

The Giants signed Hentges (shoulder/knee) to a one-year, $1.4 million contract Thursday, Robert Murray of FanSided.com reports.

Non-tendered by the Guardians last week, Hentges missed the entire 2025 season while recovering from left shoulder surgery and also underwent arthroscopic right knee surgery in September. The expectation is that he will be ready for spring training. Hentges could be a weapon for the Giants if he can regain his pre-surgery form, as he held a 2.93 ERA and 155:42 K:BB over 138 regular-season innings from 2022-to-2024 after being moved to a relief role.

The Marlins re-signed Zuber to a minor-league contract Wednesday.

Zuber got into 10 games between the Mets and Marlins in 2025, yielding 15 runs over 12 frames. The 30-year-old reliever has a career 6.26 ERA at the big-league level but has struck out 73 across 64.2 innings. Zuber is likely to start next season at Triple-A Jacksonville.
