The Detroit Tigers placed outfielder Kerry Carpenter on the 10-day injured list Thursday with a back issue.
The 25-year-old rookie has a left lumbar spine strain and finishes the season with a .252 average, six homers and 10 RBIs in 31 games.
The Tigers also placed right-hander Matt Manning on the 60-day injured list with a right forearm strain after he was scratched from Wednesday's game due to arm fatigue.
Manning, 24, finishes the season with a 2-3 record and 3.43 ERA in 12 starts. He missed three months earlier this season with shoulder inflammation.
In corresponding transactions, Detroit called up right-hander Miguel Diaz and utility player Kody Clemens from Triple-A Toledo before Thursday's game against the visiting Kansas City Royals.
