The Detroit Tigers signed former St. Louis Cardinals closer Trevor Rosenthal to a minor league deal after he threw a bullpen session Saturday at Comerica Park.
The veteran right-hander pitched in 12 games this season with the Washington Nationals, posting a 22.74 ERA.
The 29-year-old Rosenthal had 121 saves in six seasons with the Cardinals and was an All-Star in 2015. He underwent Tommy John surgery in 2017 and missed all of the 2018 season.
Rosenthal will be assigned to Triple-A Toledo.
