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.

Chavis signed a minor-league contract with the Reds on Wednesday that includes an invitation to big-league spring training, Kiley McDaniel of ESPN.com reports.

Chavis spent the entirety of 2025 with the Dodgers' Triple-A affiliate, slashing .291/.350/.547 with 13 homers, 45 RBI and 45 runs scored across 283 plate appearances. The 30-year-old infielder will get a chance to compete for a roster spot during spring camp, but he'll most likely return to the minors to begin the '26 campaign.

Mervis signed a minor-league contract with the Nationals on Wednesday, Bobby Blanco of MASNSports.com reports.

Mervis, who turns 28 shortly after Opening Day, has a career .165/.238/.322 slash line with 10 home runs, a 7.7 percent walk rate and a 34.5 percent strikeout rate in 261 MLB plate appearances over the past three seasons. He has been worth -1.5 fWAR over that span, in part because he is also a negative defender at first base. Mervis is a native of Washington D.C. and will be competing with players like Jose Tena, Warming Bernabel and Yohandy Morales for opportunities this year if injuries strike the big club.

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 Pirates signed O'Hearn to a two-year, $29 million contract Tuesday, Robert Murray of FanSided.com reports.

He'll have the opportunity to stretch the total guarantee to $30 million if he reaches $500,000 in incentives each year of the deal. O'Hearn has slashed .277/.343/.445 over the last three regular seasons between the Orioles and Padres and made his first All-Star team in 2025. The left-handed hitter reversed a career trend and hit better versus lefties (.832 OPS) than righties (.795 OPS) in 2025, so he could be an everyday player in Pittsburgh. With Spencer Horwitz manning first base, O'Hearn will likely see most of his playing time at designated hitter.

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.

Young is expected to see the majority of playing time at second base for the Mariners in 2026 even if the team acquires a second baseman from outside the organization, Ken Rosenthal and Will Sammon of The Athletic report.

The Mariners remain very high on Young even after he had just a .607 OPS in 257 plate appearances during his rookie season. Young is just 22, but the Mariners appear committed to giving him some leash in the majors in 2026. It seemingly makes a trade for Ketel Marte unlikely, and if Brendan Donovan is acquired, he would be in line to see the bulk of his reps at a position other than second base.
