The Tigers removed reliever Juan Rincon from the active roster in order to make room for Dontrelle Willis. Rincon is 1-0 with a 5.23 ERA in 10 1/3 innings this season. He was designated for assignment, which means the Tigers have 10 days to move him. If he doesn?t go to another big-league club, the Tigers would like to send him to Triple-A Toledo. If he refuses that assignment, he would become a free agent and would forfeit the remainder of his contract.
