The Detroit Tigers claimed left-handed reliever Sean Guenther off waivers from the Miami Marlins, the team announced Wednesday.
Guenther, 26, underwent Tommy John surgery in April 2022 and is on the 60-day injured list. The Tigers now have 10 players on the 60-day injured list that must be reinstated to the 40-man roster by the fifth day after the World Series ends.
The Tigers have claimed three players off waivers since president of baseball operations Scott Harris took control of day-to-day operations in early October: Guenther, catcher Michael Papierski and utility player Jermaine Palacios.

Guenther, a seventh-round pick in the 2017 draft from Notre Dame, pitched 14 games out of the Marlins’ bullpen in 2021. He posted a 9.30 ERA with 10 walks and 15 strikeouts across 20⅓ innings, with a 47.2% ground-ball rate.
In April 2022, Guenther had Tommy John surgery.
Guenther began his professional career as a starting pitcher but shifted to the bullpen in 2019. He pitched 11 games for Double-A Pensacola and 15 games for Triple-A Jacksonville in the 2021 season, registering a 3.12 ERA with seven walks and 54 strikeouts across 40⅓ between the two affiliates.
At the Triple-A level, Guenther averaged 11.1 strikeouts and 1.6 walks per nine innings.
Here’s the Tigers’ full list of players on the 60-day injured list: Guenther, Beau Brieske, Kyle Funkhouser, Rony García, Matt Manning, Casey Mize, Tarik Skubal, Spencer Turnbull, Jake Rogers and Austin Meadows.
Over the next week, the 40-man roster will drastically change as the offseason officially begins.
