Yahoo Sports reports: The slumping Detroit Tigers activated outfielder Kerry Carpenter from the 10-day injured list on Sunday and started him as the designated hitter in their series finale at Chicago against the White Sox. Infielder Gage Workman was optioned to Triple-A Toledo in a corresponding move. Carpenter went on the IL on May 10 with a left AC joint sprain after he crashed into the right-field wall at Kauffman Stadium in Kansas City the day before.
