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.
