The Marlins designated Weimer for assignment Tuesday.

The 26-year-old had a .715 OPS in 27 games for Miami in 2025 but will lose his place on the 40-man roster in order to create roster space ahead of the Rule 5 Draft. Weimer could be outrighted to Triple-A Jacksonville or elect to refuse the assignment and become a free agent.

The Marlins selected Kempner's contract from Triple-A Jacksonville on Tuesday.

Kempner was acquired from the Giants last winter in exchange for international bonus pool space, and the Marlins won't leave him exposed to potentially being selected during the upcoming Rule 5 Draft. Across three minor-league levels in 2025, the 24-year-old pitched to a 2.26 ERA, 1.15 WHIP and 95:40 K:BB over 67.2 innings.

The Pirates designated Holderman for assignment Tuesday, Jason Mackey of the Pittsburgh Post-Gazette reports.

With the Pirates adding six prospects to their 40-man roster in preparation for the Rule 5 Draft, Holderman will end up as one of the casualties necessary to clear space. The 30-year-old righty wasn't quite his usual self in 2025, finishing the year with a 7.01 ERA and 1.95 WHIP across 25.2 innings after entering the season with a 3.58 ERA across his three years in the big leagues. His prior performance may draw some attention from other bullpen-needy teams browsing the waiver wire.

The Marlins selected Mack's contract from Triple-A Jacksonville on Tuedsay.

Mack is one of Miami's top prospects, so it's no surprise the organization is protecting him from the Rule 5 Draft. The 22-year-old spent most of last season at Triple-A Jacksonville and had a .786 OPS with 18 homers and seven steals in 98 games.

Ellard retired from professional baseball Tuesday.

The 28-year-old Ellard will hang up his cleats after just two seasons in the majors, during which he posted a 3.95 ERA and 1.39 WHIP alongside a 48:31 K:BB across 41 innings with the White Sox.

The White Sox selected McDougal's contract from Double-A Birmingham on Tuesday.

McDougal turned in a 3.26 ERA and 1.33 WHIP to go with a 136:49 K:BB over 113.1 innings between High-A and Double-A in 2025. Considered one of the top pitching prospects in the White Sox's farm system, the 22-year-old will officially receive a spot on the 40-man roster to prevent another team from selecting him in the Rule 5 Draft, and he has a strong chance to make his MLB debut in 2026 and join a talent-deficient White Sox rotation.

The Red Sox selected Drohan's contract from Triple-A Worcester on Tuesday, Chris Cotillo of MassLive.com reports.

Drohan missed nearly four months of the Triple-A season with a forearm injury but was extremely effective when healthy, turning in a 2.27 ERA and 1.02 WHIP alongside a 67:16 K:BB through 47.2 innings. The 26-year-old southpaw will be ineligible for the Rule 5 Draft in December now that he owns a spot on Boston's 40-man roster, and he could compete for a spot on the Opening Day roster if his strong performance continues into spring training.

The Red Sox selected Sandlin's contract from Triple-A Worcester on Tuesday, Chris Cotillo of MassLive.com reports.

Sandlin began 2025 at Double-A Portland and posted a 3.61 ERA and 1.18 WHIP across 82.1 innings before receiving a promotion to Worcester. The 24-year-old righty struggled upon arriving at Triple-A (7.61 ERA, 2.07 WHIP), but the Red Sox will give him a 40-man spot to ensure he remains with the organization past December's Rule 5 Draft. He is likely to report to Worcester to begin the 2026 season.

The Red Sox traded Murphy to the White Sox on Tuesday in exchange for Ronny Hernandez, Bob Nightengale of USA Today reports.

Murphy was effective as a big-league reliever in 2025, finishing the regular season with a 3.12 ERA and 1.18 WHIP across 34.2 innings. The White Sox aren't working with much depth in their bullpen, so the 27-year-old left-hander could see regular work in high-leverage opportunities with his new organization.

The Angels selected Urena's contract from Triple-A Salt Lake on Tuesday.

The right-hander spent most of the 2025 campaign at Double-A Rocket City, where he had a 4.33 ERA, 1.35 WHIP and 121:74 K:BB across 139.1 innings. Urena moved up to Triple-A for his final outing of the season and could be back at the highest level of the minors to begin 2026.
