The Yankees selected Castro's contract from Triple-A Scranton/Wilkes-Barre on Thursday.

Castro dominated minor-league hitters in 2025, turning in a 1.53 ERA, 1.04 WHIP and 52:22 K:BB across 47 innings with Scranton/Wilkes-Barre. He'll be rewarded with a place on New York's 40-man roster as a result of his performance, and he'll have a chance to win a spot in the Yankees' bullpen during spring training.

The Cardinals outrighted Thompson (lat) to Triple-A Memphis on Thursday, Derrick Goold of the St. Louis Post-Dispatch reports.

Thompson missed the entire 2025 season with a left lat strain he suffered in March. He endured several setbacks during his recovery, and it's unclear whether he will be ready for spring training. Thompson is now off the 40-man roster but will remain in the organization.

Atlanta claimed Siani off waivers from the Cardinals on Thursday, Jeff Jones of the Belleville News-Democrat reports.

Siani, who turns 27 in July, appeared in just 19 games for the Cardinals in 2025 after logging 334 plate appearances for the team in 2024. The defense-first outfielder will head to Atlanta with hopes of securing a larger role. Siani slashed .209/.307/.329 with eight home runs and 28 stolen bases for the Cardinals' Triple-A affiliate last season.

The Cardinals selected Torees' contract Thursday, Jeff Jones of the Belleville News-Democrat reports.

The move ensures Torres won't become a minor-league free agent. The outfielder, who turns 29 in July, hasn't made his MLB debut yet. He slashed .326/.441/.456 with nine homers and 28 stolen bases in 2025 for Triple-A Memphis.

The Rays activated Van Belle (elbow) from the 60-day injured list and designated him for assignment Thursday.

Van Belle suffered a UCL sprain in September, and it's unclear if the injury will be addressed via rest and rehab or surgery. Regardless, the 29-year-old will be placed on waivers. He appeared in four games with Tampa Bay in 2025, marking his first MLB action.

The Pirates selected Harbin's contract from Triple-A Indianapolis on Thursday, Alex Stumpf of MLB.com reports.

Harbin began 2025 at High-A Greensboro but managed to reach Triple-A Indianapolis by season's end, and he'll now begin the offseason by securing a place on Pittsburgh's 40-man roster. The 24-year-old righty figures to have an outside chance to make the Pirates' Opening Day roster, but considering he gave up 17 earned runs in just 13.1 innings at Indianapolis, the team may look to get him more reps in Triple-A before letting him make his MLB debut.

The Rays activated Lavender (elbow) from the 60-day injured list and designated him for assignment Thursday.

Lavender underwent surgery in late August or early September to remove a bone spur from his left elbow. It's possible he'll be available for the start of spring training. However, he'll be exposed to waivers after Thursday's move. Lavender, who turns 25 in January, has yet to make his MLB debut.

Fairchild cleared waivers and elected free agency Thursday.

Fairchild will test the open market after being designated for assignment earlier this week. The outfielder appeared in 28 big-league games this season -- all for Atlanta -- and slashed .216/.273/.333 across 55 plate appearances.

Faedo (shoulder) cleared waivers and elected free agency Thursday.

After being designated for assignment by Tampa Bay earlier this week, Faedo will hit the open market. Faedo underwent season-ending thoracic outlet syndrome surgery in early August, and it's uncertain if he'll be available for the start of 2026.

The Pirates designated Darnell (hip) for assignment Thursday.

Thursday marks the second time in six days that Darnell has been DFA'd, as he joined the Pirates via waiver claim from Colorado last Friday. The 28-year-old righty posted a 3.19 ERA and 1.15 WHIP across 53.2 Triple-A innings during 2025 despite playing in the hitter-friendly Pacific Coast League, giving him a fair amount of appeal for bullpen-needy teams browsing the waiver wire.
