The Tigers added the former Astros closer for a prospect prior to Thursday's trade deadline. He has spent the 2025 season between the Astros and Braves, combining for a 5.40 ERA, although his 4.38 xFIP and 4.31 SIERA suggest some improvement should be had moving forward.

He has worked to a 5.40 ERA in 39 outings between the Astros and Braves in 2025, but his 4.38 xFIP and 4.31 SIERA suggest he has been better than his surface ERA suggests.
