Hamilton signed a one-year, non-guaranteed contract with Atlanta on Friday.

Hamilton finished 2025 with a 4.28 ERA and 1.25 WHIP across 40 regular-season innings -- the worst numbers of his three-year tenure in the Bronx. The 30-year-old righty will now attempt to land a spot in Atlanta's bullpen, but even if he makes the big-league club, he won't be likely to receive many high-leverage opportunities with Raisel Iglesias, Robert Suarez, Dylan Lee and Joe Jimenez (knee) already on the roster.

The Mets outrighted Waddell to Triple-A Syracuse on Friday, Anthony DiComo of MLB.com reports.

New York designated Waddell for assignment earlier this week, and he'll remain in the organization after clearing waivers. Waddell posted a 3.45 ERA, 1.28 WHIP and 22:11 K:BB across 31.1 major-league innings last season.

Arizona outrighted Jarvis to Triple-A Reno on Friday, Alex Weiner of ArizonaSports.com reports.

Jarvis was booted from the 40-man roster and designated for assignment last Friday but cleared waivers and will remain with the Diamondbacks' organization. The 27-year-old right-hander appeared in 12 games at the big-league level with Arizona last season and carded a 5.73 ERA, 1.50 WHIP and 21:10 K:BB across 22 innings.

The Phillies acquired Backhus from the Diamondbacks on Friday in exchange for Avery Owusu-Asiedu, Matt Gelb of The Athletic reports.

Backhus is a sidearming lefty reliever who held left-handed hitters to just a .139/.225/.278 slash line in 2025. Righty bats slashed .365/.417/.571 off the 27-year-old, so manager Rob Thomson will have to be judicious with his usage of Backhus.

The Phillies acquired Bowlan from the Royals on Friday in exchange for Matt Strahm, Mark Feinsand of MLB.com reports.

Bowlan had a mini-breakout in 2025 in his first full season as a reliever, posting a 3.86 ERA and 46:17 K:BB over 44.1 innings with the Royals. The 29-year-old righty had significant splits, as he held right-handed bats to a .182/.255/.250 batting line but was torched by lefties to the tune of a .288/.358/.575 line. Bowlan is not yet eligible for salary arbitration and will be under team control through 2031.

King agreed to a one-year contract with the Padres on Thursday that includes player options for 2027 and 2028, Mark Feinsand of MLB.com reports.

King had two excellent seasons with the Padres in 2024 and 2025 and passed on a qualifying offer with the team earlier in the offseason, but he'll ultimately remain with San Diego. According to Feinsand, King will make $17 million in 2025 and will net at least another $5 million in the form of a buyout for the 2027 option. His player options for 2027 and 2028 are worth $28 million and $30 million, respectively. Assuming King can avoid any lingering issues with his shoulder -- which cost him much of the 2025 season -- he should headline the Padres' rotation in 2026.

The Diamondbacks re-signed Curtiss to a minor-league contract Tuesday.

Curtiss had chosen free agency after being booted off Arizona's 40-man roster last month, but he's now back in the organization on a new deal. The 32-year-old pitched well in 30 relief outings for the Diamondbacks in 2025, collecting a 3.93 ERA, 0.93 WHIP and 24:5 K:BB over 36.2 innings. Curtiss is likely headed to Triple-A Reno to begin the 2026 season.

The Mets designated Waddell for assignment Wednesday.

The move clears a spot on the 40-man roster for Drew Romo, who was claimed off waivers. Waddell had re-signed with the Mets last month after proving useful in a swingman role in 2025, holding a 3.45 ERA and 22:11 K:BB over 31.1 innings. If he clears waivers, Waddell would have the ability to elect free agency.

Garabito signed a minor-league contract with the Brewers on Wednesday that includes an invitation to spring training, Adam McCalvy of MLB.com reports.

Garabito finished the 2025 season with the Samsung Lions of the Korea Baseball Organization, holding a 2.64 ERA and 84:37 K:BB over 78.1 innings covering 15 starts. The 30-year-old has made 21 appearances (two starts) at the big-league level, producing a 5.77 ERA. Garabito is likely to begin the 2026 season in the rotation at Triple-A Nashville.

The Mets signed Weaver to a two-year, $22 million contract Wednesday, Anthony DiComo of MLB.com reports.

Weaver becomes the second former Yankees reliever to sign with the Mets this offseason, joining closer Devin Williams. The 32-year-old Weaver struggled at times during the second half in 2025, but he finished his tenure in pinstripes with a 3.22 ERA and 191:49 K:BB across 162 regular-season innings. Weaver will help set up for Williams with the Mets.
