The White Sox did not tender Booser a contract for 2026 on Friday.

Booser was acquired from the Red Sox last winter and made 39 appearances for the White Sox in 2025, finishing with a 5.52 ERA, 1.52 WHIP and 35:19 K:BB over 31 innings.

The Mets non-tendered Young on Friday.

Young made the Mets' Opening Day roster, but his 2025 season was cut short after undergoing Tommy John Surgery in May. If he does manage to sign with a team, he's unlikely to be healthy enough to contribute until at least the second half of the 2026 campaign.

De Los Santos signed a one-year contract with the Astros on Friday, Brian McTaggart of MLB.com reports.

De Los Santos put up a 4.03 ERA and 1.25 WHIP over 22.1 innings after signing with the Astros in August, and his new deal will ensure he remains in the organization for the start of the 2026 campaign -- likely serving as a middle reliever.

The Mets non-tendered Castillo on Friday.

Just two weeks after claiming Castillo off waivers from Baltimore, the Mets will now send him into free agency. The 29-year-old southpaw posted a 3.94 ERA and 1.69 WHIP across 32 innings between four different teams in 2025. He'll now have an opportunity to pick where he begins the 2026 campaign, though he may have to settle for a minor-league deal.

The Rangers non-tendered Webb on Friday.

Webb signed a one-year deal with the Rangers in December after spending the 2024 campaign with the Orioles, but the 32-year-old right-hander will now be on the lookout for a team in need of bullpen depth. He finished the 2025 regular season with seven holds along with a 3.00 ERA, 1.03 WHIP and 58:19 K:BB across 66 innings.

The Rangers non-tendered Sborz on Friday.

Sborz started the 2025 season on the 60-day injured list after undergoing surgery on his right shoulder in November of 2024. He was able to begin a rehab stint in July but was unable to progress enough in his recovery to see major-league action. Sborz will now enter free agency and will look to sign with a team in need of right-handed depth out of the bullpen.

The Royals non-tendered Clarke on Friday.

Clarke enjoyed the best season of his MLB career in 2025, turning in a 3.25 ERA and 0.85 WHIP alongside a 44:9 K:BB across 55.1 innings. Despite his success, the Royals will elect to let the 32-year-old righty enter free agency, where his breakout campaign is likely to draw some interest from bullpen-needy teams.

The Red Sox non-tendered Winckowski (elbow) on Friday, Chris Cotillo of MassLive.com reports.

Winckowski was pushed off Boston's 40-man roster Tuesday and will now exit the organization altogether after not receiving a contract offer for 2026. The 27-year-old allowed five earned runs in 11.2 innings with the Red Sox in April before being sent down to Triple-A, where he ended the season on the injured list after suffering an elbow strain in mid-May. It's unclear whether he'll be ready for the start of spring training.

The Dodgers did not tender Phillips (elbow) a contract for 2026 on Friday, making him a free agent, Ken Rosenthal of The Athletic reports.

The right-hander made just seven appearances in 2025 before undergoing Tommy John surgery in June, which will sideline him for at least the first half of the 2026 campaign. According to Jack Harris of the Los Angeles Times, the Dodgers are interested in re-signing Phillips at a lower salary.

The Orioles non-tendered Suarez (forearm) on Friday.

Suarez turned in a 2.31 ERA and 0.94 WHIP over 11.2 innings in 2025 while healthy, though that was a rare occasion, as he missed five months of the year with a shoulder injury before landing on the injured list again in September with a flexor strain in his right forearm. The 36-year-old righty posted a 3.70 ERA and 1.29 WHIP over 133.2 frames during his latest full season in 2024, which could still be enough to draw interest from other clubs in free agency.
