The Cubs acquired Cabrera from the Marlins on Wednesday in exchange for Owen Caissie, Cristian Hernandez and Edgardo De Leon, Jeff Passan of ESPN.com reports.

Cabrera experienced a breakthrough in 2025 after lowering his arm slot, finishing the season with a 3.53 ERA, 1.23 WHIP and 150:48 K:BB across 137.2 innings. It was a career-high workload for the righty, and he will remain a major injury risk moving forward, but Cabrera injects some much-needed upside and bat-missing ability into the Cubs' rotation. He is under team control through 2028.

The Cubs claimed Rolison off waivers from the White Sox on Wednesday, Bruce Levine of 670TheScore.com reports.

It's the fourth organization since November for Rolison, who posted a 7.02 ERA and 25:20 K:BB over 42.1 innings with the Rockies in 2025. The left-hander will compete for a spot in the Cubs' bullpen, but he does have minor-league options remaining.

The Rockies claimed Thompson off waivers from the Reds on Wednesday.

Thompson signed a one-year, $1.3 million split contract with the Reds in November, but he was booted off their 40-man roster in December and is now headed to Colorado. He's been used almost exclusively in relief over the past three seasons, but Thompson does have past starting experience, so the Rockies could consider him in a swingman role.

The Reds outrighted Richardson to Triple-A Louisville on Wednesday.

Richardson is no longer on the 40-man roster but will remain in the organization after passing through waivers unclaimed. The right-hander finished 2025 with a 4.54 ERA, 1.54 WHIP and 30:21 K:BB across 37.2 regular-season innings for Cincinnati.

The Giants designated Dean for assignment Tuesday, Susan Slusser of the San Francisco Chronicle reports.

Dean arrived in San Francisco in November via waiver claim, but he'll now depart the 40-man roster to make room for Tyler Mahle. Dean slashed .289/.378/.431 and stole 27 bases across 347 plate appearances with the Dodgers' Triple-A affiliate in 2025, and he's likely to work as minor-league depth again in 2026.

The Cardinals designated Kent for assignment Tuesday.

The move clears a spot on the 40-man roster for the addition of Justin Bruihl, who was acquired via trade. Kent was a waiver claim by the Cardinals in December and will now go through the waivers process again. The righty reliever posted a 4.58 ERA and 16:8 K:BB over 17.2 innings for the Guardians in 2025.

The Cardinals acquired Bruihl from the Guardians on Tuesday in exchange for cash considerations.

Bruihl has bounced around from the Blue Jays to the Guardians and now to the Cardinals since mid-December. The left-handed reliever holds a career 4.72 ERA and 69:32 K:BB over 89.2 frames covering parts of five major-league seasons. Bruihl does not have minor-league options remaining, so he's a good bet to make the Opening Day roster if he's still with St. Louis in spring training.

Keirsey signed a minor-league contract with Atlanta on Dec. 18.

Keirsey has found a new home with Atlanta after being non-tendered by the Twins and electing free agency in November. The outfielder appeared in 74 matchups with Minnesota during the 2025 season, struggling to a .107 average with two home runs, six RBI, 10 stolen bases on 13 attempts and 11 runs scored.

The Nationals claimed Wiemer off waivers from the Giants on Monday, Robert Murray of FanSided.com reports.

It's the third organization Wiemer has been in since November and fourth since August. The 26-year-old slashed .236/.279/.436 with a 2:23 BB:K over 27 contests for the Marlins in 2025. Wiemer is out of minor-league options, so he should have a good chance to make the Nationals' Opening Day roster in a reserve role.

The Giants signed Kennedy to a minor-league contract Dec. 15.

Kennedy spent a little time in the majors with three different teams in 2025, going just 2-for-29 at the plate. The 27-year-old will likely begin the 2026 season at Triple-A Sacramento, where he'll give the Giants some experienced infield depth.
