Guenther (hip) was designated for assignment by the Tigers on Tuesday, Cody Stavenhagen of The Athletic reports.

Left hip surgery ended Guenther's season in early July after he made nine appearances (one start) with the big-league club over the first two months of the campaign. The left-hander put an impressive 0.86 ERA and 0.52 WHIP in 21 innings out of the Detroit bullpen during the 2024 regular season, and that run of success may be enough to land him on another team's 40-man roster.

The Tigers designated Foley (shoulder) for assignment Tuesday, Cody Stavenhagen of The Athletic reports.

Widely considered the favorite to close for Detroit entering 2025 spring training, Foley didn't even end up making it to Opening Day, with the Tigers choosing instead to send him to Triple-A Toledo. A right shoulder strain then put Foley on the injured list just weeks into the campaign, leading to season-ending arthroscopic surgery in May. While Foley resumed throwing before the end of the regular season, his status for the start of the 2026 season is uncertain.

The Royals selected Zobac's contract from Double-A Northwest Arkansas on Tuesday, Anne Rogers of MLB.com reports.

The right-hander missed time in 2025 due to a knee injury, which limited him to 14 appearances. Zobac spent most of the campaign with Northwest Arkansas and had a 7.68 ERA over 36.1 innings, but the Royals still elected to shield him from potentially being selected in the upcoming Rule 5 Draft.

The Royals selected Kudrna's contract from Triple-A Omaha on Tuesday, Anne Rogers of MLB.com reports.

The 22-year-old righty spent most of last season at Double-A Northwest Arkansas, where he had a 4.21 ERA over 94 innings. Kudrna made four appearances for Omaha late in the season and struggled at the highest level of the minors with a 14.29 ERA.

Darnell (hip) was designated for assignment by the Tigers on Tuesday, Cody Stavenhagen of The Athletic reports.

Darnell received his first big-league call-up in August and made nine appearances with the Rockies before landing on the injured list with left hip inflammation. Surgery was deemed necessary, and Darnell has since jumped to Pittsburgh and Detroit on waivers. He will be subjected to the waiver process once again after being DFA'd.

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 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 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.
