Trent Thornton: Everything you need to know

The Cubs signed Thornton (Achilles) to a contract Monday, Tread Athletics reports. It's not clear whether it's a major- or minor-league contract, but Thornton has landed a deal after throwing for teams in a "Pro Day" at Tread Athletics training facility. Thornton had surgery in August to repair a torn left Achilles tendon but has a chance to be ready in time for Opening Day. The right-handed reliever posted a 4.68 ERA, 1.30 WHIP and 32:14 K:BB over 42.1 innings for the Mariners in 2025 before getting hurt.

The Mariners non-tendered Thornton on Friday, Daniel Kramer of MLB.com reports. Thornton's 2025 season came to an abrupt halt in late July after he tore a left Achilles tendon. Prior to the injury, Thornton posted five holds along with a 4.68 ERA, 1.30 WHIP and 32:14 K:BB across 42.1 innings while operating out of the bullpen. Thornton's expected timeline to recover was estimated as 6-to-8 months after undergoing surgery in August, which will impact his availability for spring training should he sign with a team.

The Mariners transferred Thornton (Achilles) from the 15-day injured list to the 60-day injured list Tuesday. The transaction frees up a spot on the 40-man roster for the addition of Sauryn Lao. Thornton is out for the season after tearing his left Achilles on July 31.
