Harvey (groin) signed a one-year contract with the Cubs on Saturday, Will Sammon of The Athletic reports.

Shoulder and adductor injuries limited Harvey to just 12 appearances with the Royals this past season, during which he struck out 11 batters and walked one over 10.2 shutout innings. The 31-year-old righty boasts a 3.11 ERA and 1.10 WHIP across his big-league career and will likely see action in high-leverage spots with the Cubs, though he doesn't project to take many save chances away from Daniel Palencia.

The Reds designated Thompson for assignment Saturday.

Thompson signed a major-league contract with the Reds in November, but he'll now be kicked off the 40-man roster to make room for JJ Bleday. The 30-year-old Thompson owns a 3.64 ERA across his MLB career but spent the entire 2025 campaign with the Cubs' Triple-A affiliate, posting a 4.43 ERA and 1.42 WHIP over 65 innings.

White signed a one-year contract with the Hanwha Eagles of the Korea Baseball Organization on Wednesday, Dan Kurtz of MyKBO.net reports.

White has struggled during his brief stints in the big leagues, allowing 20 earned runs over just 14 innings in his MLB career. He fared a bit better at Triple-A Charlotte in 2025, posting a 4.44 ERA and 1.44 WHIP over 81 frames, and he'll now aim to further hone his craft overseas.

Fairbanks and the Marlins agreed Wednesday on a one-year, $13 million contract, Jeff Passan of ESPN.com reports.

Tampa Bay declined Fairbanks' $11 million club option for 2026 earlier this offseason, but the reliever ended up securing an extra $2 million after hitting the open market. The deal also includes a $1 million signing bonus and another $1 million in appearance-based incentives, per Mark Feinsand of MLB.com. The Marlins took a committee approach to the closer position in 2025, but Fairbanks' contract should give him some security as the Marlins' preferred ninth-inning man heading into spring training. Though staying healthy has often been an issue for Fairbanks throughout his career, he continued to pitch effectively in his age-31 season in 2025, logging a 2.83 ERA, 1.04 WHIP and 59:18 K:BB while converting 27 of 32 save chances across 60.1 innings with the Rays.

The Cubs signed Webb to a one-year contract Tuesday that includes a club option for 2027, Patrick Mooney of The Athletic reports.

Webb was non-tendered by the Rangers last month even after posting a 3.00 ERA, 1.03 WHIP and 58:19 K:BB across 66 innings during the 2025 season. The 32-year-old right-hander should fill a middle-relief role in the Cubs' bullpen.

The Pirates signed Mosqueda to a minor-league contract Tuesday that includes an invitation to spring training.

Mosqueda pitched for Triple-A Memphis in the Cardinals organization in 2025, holding a 4.52 ERA and 68:31 K:BB over 65.2 innings. The left-handed reliever has yet to reach the big leagues but will compete for a roster spot in spring training.

The White Sox designated Rolison for assignment Tuesday.

The transaction frees up a spot on the 40-man roster for Sean Newcomb, who was signed Tuesday. Rolison was a waiver claim of the White Sox earlier this month and will now be up for grabs on waivers again. He held a 7.02 ERA and 25:20 K:BB over 42.1 innings with the Rockies in 2025.

The White Sox signed Newcomb (elbow) to a one-year, $4.5 million contract Tuesday.

Newcomb was terrific as a full-time reliever after being traded to the Athletics last season, collecting a 1.75 ERA and 50:14 K:BB over 51.1 innings. The left-hander will get an opportunity to start in Chicago, per Will Sammon of The Athletic, though he could eventually shift back to a relief role. Newcomb's 2025 campaign ended prematurely due to left elbow inflammation, but he should be ready to go for spring training.

Henriquez underwent a UCL reconstruction surgery with an internal brace procedure on his right elbow and will miss the 2026 season, Christina De Nicola of MLB.com reports.

Henriquez appeared in line to compete for save chances heading into the 2026 campaign after putting together an impressive 2025 season. He posted a 2.22 ERA and 1.10 WHIP with a 98:27 K:BB and seven saves in 11 chances across 73.0 innings. However, he'll now shift his focus to rehabbing following a recent season-ending surgery. The Marlins expect him to be ready for next year's spring training, per an update from the team.

The Tigers re-signed Mattison to a minor-league contract Dec. 18 that includes an invitation to spring training, Evan Petzold of the Detroit Free Press reports.

Mattison was non-tendered by the Tigers last month, but he's now back in the organization and will be in big-league camp this spring. The righty reliever boasts a 32.8 percent strikeout rate in the minors but has been held back by a bloated 13.4 percent walk rate.
