The Cardinals selected Bernal's contract from Double-A Springfield on Tuesday, John Denton of MLB.com reports.

Bernal spent the entire 2025 campaign at Springfield and slashed .247/.332/.394 with 13 homers, 69 RBI, 58 runs scored and 13 steals across 454 plate appearances. The 21-year-old backstop will be ineligible for the Rule 5 Draft now that he owns a 40-man spot, and he could potentially receive a promotion to Triple-A Memphis to begin 2026.

The White Sox traded Hernandez to the Red Sox on Tuesday in exchange for Chris Murphy, Chris Henrique of BostonSportsJournal.com reports.

Hernandez spent the entire 2025 season with the White Sox's Single-A affiliate, slashing .251/.344/.336 over 355 plate appearances. He could receive a bump up to High-A upon joining the Red Sox's farm system, but the 21-year-old backstop doesn't appear to be on the verge of making his MLB debut anytime soon.

The Tigers selected Liranzo's contract from Double-A Erie on Tuesday, Cody Stavenhagen of The Athletic reports.

With that, Liranzo is now ineligible to be selected in next month's Rule 5 Draft. Liranzo endured a harsh dose of reality in his first go at the Double-A level in 2025, as he limped to a .206/.308/.351 slash line in 88 games. However, the Tigers clearly still believe that he will contribute eventually between catcher, first base and DH.

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

Moreta turned in a 3.24 ERA and 1.38 WHIP across 16.2 innings with the Pirates in 2025, and he also finished with a 2.43 ERA over 37 frames at Triple-A Indianapolis. Despite his strong performance, he'll lose his place on Pittsburgh's 40-man roster to make room for a wave of prospects, though another club may be interested in claiming Moreta off waivers.

The Padres selected Mendez's contract from Double-A San Antonio on Tuesday.

The right-hander is one of San Diego's top prospects, so his addition to the 40-man roster was to be expected ahead of the Rule 5 Draft. Mendez posted a 1.78 ERA and 11.2 K/9 over 75.2 frames in the lower minors during 2025 but surrendered 20 earned runs over six late-season starts after being promoted to Double-A.

The Tigers selected Lee's contract from Triple-A Toledo on Tuesday, Cody Stavenhagen of The Athletic reports.

Lee was one of five players added for Rule 5 protection. While Lee is not exactly an imposing presence in the batter's box at 5-foot-9, he has displayed admirable plate skills and enough power and speed to project as a major-league prospect. The infielder spent his age-22 season at Toledo, slashing .243/.342/.406 with 14 homers and 22 steals across 579 plate appearances.

The Pirates designated Simon (shoulder) for assignment Tuesday, Jason Mackey of the Pittsburgh Post-Gazette reports.

Simon appeared in 27 MLB games in 2025 between Miami and Pittsburgh, slashing just .234/.299/.273 across 88 plate appearances. He finished the Triple-A season with an .844 OPS over 308 plate appearances, however, which may be good enough for another team to bring him in via waiver claim.

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

Canario slashed .218/.274/.338 with 20 RBI and 25 runs scored across 234 plate appearances with the Pirates in 2025. He'll now end up as one of the roster casualties necessary to clear room for the six prospects Pittsburgh added to its 40-man Tuesday.

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.
