Stock signed a minor-league contract with the Mets on Tuesday, Michael Mayer of MetsmerizedOnline.com reports.

Stock saw major-league action for the first time since 2021 this past season and gave up three earned runs over 2.2 innings with the Red Sox. He was more successful at Triple-A Worcester, finishing the year with a 3.92 ERA and 1.33 WHIP over 85 frames. He will most likely begin 2026 at Triple-A Syracuse.

Leahy is expected to open the 2026 season in the Cardinals' rotation, Jeff Jones of the Belleville News-Democrat reports.

The trade of Sonny Gray to the Red Sox further depleted St. Louis' rotation depth, and, barring a poor showing during spring training, it sounds like Leahy will win one of the five rotation slots. Leahy threw three innings in the Cardinals' final regular season game in 2025 in what was his first-ever start at the major-league level. He did work multiple frames out of the bullpen often this season, but Leahy has not been used as a starter regularly since 2022. If he is indeed in the rotation in 2026, some workload restrictions are likely to be in place,

The Rockies signed Mushinski to a minor-league contract with an invitation to spring training Monday, Kevin Henry of The Denver Gazette reports.

Mushinski spent the entirety of the 2025 campaign at Triple-A Columbus in the Guardians organization, holding a 3.78 ERA and 66:33 K:BB over 50 innings. The lefty reliever has made 31 appearances at the big-league level, collecting a 5.45 ERA and 26:12 K:BB across 33 frames. Mushinski will compete for a spot in Colorado's Opening Day bullpen but will likely begin the year at Triple-A Albuquerque.

Atlanta signed Payamps to a one-year, $2.25 million contract Sunday.

Payamps joined Atlanta as a waiver claim in late September and was outrighted to Triple-A on Nov. 6. That move was likely made by the team to avoid an arbitration hearing, as the $2.25 million agreed to by the sides Sunday is probably less than what the veteran reliever would have received in arbitration. Regardless, Payamps now seems ticketed for a role in Atlanta's bullpen in 2026. He's had plenty of major-league success but will be looking to rebound from a career-worst 2025 campaign during which he posted a 6.84 ERA, 1.52 WHIP and 24:9 K:BB over 26.1 innings across 30 appearances between Atlanta and Milwaukee.

Laskey agreed to a minor-league contract with the Rockies on Sunday, Aram Leighton of JustBaseball.com reports.

Laskey spent 2025 in the Marlins organization and split his time between the Double-A and Triple-A levels. He received an invitation to big-league spring training but is likely to open 2026 in the minors based on his production last year and the fact that he's yet to make his MLB debut.

Maton signed a two-year contract with the Cubs on Friday, Will Sammon of The Athletic reports.

Maton's new deal also includes a club option for 2028. The 32-year-old spent time with the Cardinals and Rangers in 2025, finishing the regular season with a 2.79 ERA and 1.06 WHIP along with an 81:23 K:BB across 61.1 innings. Now with the Cubs, he's sure to continue pitching in high-leverage situations and will presumably be in the mix for saves alongside Daniel Palencia.

Brubaker signed a one-year contract with the Giants on Friday, Susan Slusser of the San Francisco Chronicle reports.

Brubaker enjoyed his most successful season in the majors while working primarily as a reliever in 2025, logging a 3.77 ERA and 1.22 WHIP over 28.2 innings between the Yankees and Giants. The 32-year-old righty will likely compete for a rotation spot during spring training, though he could also be used as a long reliever again if he misses the cut.

The Reds and Moll avoided arbitration by agreeing to a one-year, $875,000 contract, Jon Heyman of the New York Post reports.

He'll have a chance to earn an additional $150,000 in incentives. Moll split his time between the Reds and Triple-A Louisville in 2025, posting a 6.38 ERA and 22:10 K:BB over 18.1 frames with the big club. The lefty reliever does not have minor-league options remaining, so he would have to pass through waivers in order to be sent down.

Atlanta and Suarez avoided arbitration by agreeing to a one-year contract Friday.

Suarez made seven appearances (one start) with Atlanta in 2025, finishing with a 1.86 ERA and 16:10 K:BB across 19.1 innings of work. The left-hander holds a career 5.30 ERA over parts of seven major-league seasons and does not have minor-league options remaining, so he could open the 2026 campaign as a long reliever.

Ramirez and the Pirates agreed to a one-year, $825,000 contract Thursday, Alex Stumpf of MLB.com reports.

Ramirez had been looking at arbitration if he and Pittsburgh had not been able to agree upon a deal. The Dominican reliever appeared in 24 games with the Pirates in 2025, posting a 5.40 ERA, 1.47 WHIP and 45:16 K:BB over 33.1 innings while notching one hold and a 3-3 record.
