Duffey signed a minor-league contract with the Rangers on Friday, Evan Grant of The Dallas Morning News reports.
Duffey was released by the Twins on Monday after struggling to a 4.91 ERA in 44 innings this season. It's not surprising that he quickly latched on with another club, however, as he cruised to a 2.69 ERA from 2019 to 2021. A modest bounceback would make Duffey a useful option down the stretch for the Rangers, and a full return to his previous form would make him one of the team's best relievers.
