The Orioles selected Foster's contract from Triple-A Norfolk on Tuesday.

The 26-year-old was acquired from the Mets in the Gregory Soto trade over the summer, so his addition to the 40-man roster was to be expected. Foster pitched in 13 games for Triple-A Norfolk after the trade and had a 3.38 ERA, 1.38 WHIP and 23:8 K:BB over 16 innings.

The Cardinals designated Alcala for assignment Tuesday, John Denton of MLB.com reports.

Alcala struggled to find his footing on the mound in 2025, finishing the regular season with a 6.22 ERA and 1.75 WHIP across 55 total innings between Minnesota, Boston and St. Louis. He'll have the right to elect free agency if he clears waivers, although he will likely have to settle for a minor-league deal if he does so.

The Tigers designated Mattison for assignment Tuesday, Cody Stavenhagen of The Athletic reports.

Mattison was added to the 40-man roster last November, but he finds himself on the other side of Rule 5 cutdown day this time around. The right-hander has yet to make his major-league debut. He pitched mostly between Double-A and Triple-A this past season after recovering from right UCL reconstruction surgery.

Little was designated for assignment by the Tigers on Tuesday, Cody Stavenhagen of The Athletic reports.

Claimed off waivers from the Pirates earlier this month, Little ended up spending less than two weeks on the Tigers' 40-man roster. Little will now be subjected to waivers once again after spending the 2025 season primarily at the Triple-A level, making just a pair of relief appearances with the Dodgers over the summer.

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.

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 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 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.

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.
