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.

The Pirates selected Brannigan's (shoulder) contract from Double-A Altoona on Tuesday, Alex Stumpf of MLB.com reports.

Brannigan slashed .225/.329/.358 across 237 plate appearances at Double-A Altoona in 2025 before suffering a shoulder injury in June that required season-ending surgery. The 24-year-old infielder will join Pittsburgh's 40-man roster to ensure he remains with the organization past the Rule 5 Draft in December, though he shouldn't be expected to appear in the big leagues in 2026.

The Pirates selected Valdez's contract from Double-A Altoona on Tuesday, Francys Romero of BeisbolFR.com reports.

Valdez split his time between High-A and Double-A ball in 2025, slashing .284/.375/.521 with 27 homers, 87 RBI and 76 runs scored between the two levels. His impressive performance will grant him a place on Pittsburgh's 40-man roster heading into the 2026 campaign, but he's likely to begin the year at Double-A Altoona or Triple-A Indianapolis.

Spiers (elbow) was designated for assignment by the Reds on Tuesday, Charlie Goldsmith of Fox 19 Now Cincinnati reports.

Cincinnati needed a 40-man spot for one of its young prospects, and Spiers was a likely choice to be bounced given he's expected to miss most, if not all, of 2026. The right-hander made three appearances (two starts) in the majors this past season before undergoing Tommy John surgery at the end of July. Spiers has put up a 5.69 ERA and 1.57 WHIP over 117 career innings in the majors.

The Reds selected Rodriguez's contract from Double-A Chattanooga on Tuesday, Charlie Goldsmith of Fox 19 Now Cincinnati reports.

Acquired in a rather inconspicuous trade with the Mets in 2022, Rodriguez has emerged as a legitimate major-league prospect thanks largely to his hitting ability. He advanced to the Triple-A level this past season, and while most of his numbers fell off compared to what he was doing at Double-A Chattanooga, he still hit seven homers and stole nine bags in 53 games with Louisville. Now protected from the Rule 5 Draft, Rodriguez will have a chance to debut late in 2026.

The Nationals selected Franklin's contract from Triple-A Rochester on Tuesday.

The 25-year-old was acquired from the Cubs in the Michael Soroka trade over the summer, so it's no surprise the Nationals are protecting him from the upcoming Rule 5 Draft. Franklin spent the year at the Triple-A level between the two organizations and posted an .817 OPS with 12 homers and 19 steals in 117 games.

Woodruff (lat) accepted the one-year, $22.025 million qualifying offer from the Brewers on Tuesday, Ken Rosenthal of The Athletic reports.

The veteran right-hander declined his $20 million mutual option for 2026 earlier in November, but he'll return to Milwaukee for a ninth season on the qualifying offer. Woodruff spent the first three months of the 2025 campaign rehabbing from shoulder, ankle and elbow issues, but he was effective when available with a 3.20 ERA, 0.91 WHIP and 83:14 K:BB across 64.2 innings. He went down with a lat strain in September and missed the final weeks of the season but is expected to be healthy for spring training.
