The 27-year-old righthander was a dominant, hard-throwing setup man for division rival Detroit in 2006, a head-turning rookie capable of throwing 100 mph heat who helped the Tigers advance to the World Series. He hasn't pitched an entire season since then, however, because of a series of arm problems. The latest injury was a broken elbow he suffered at Minnesota in gruesome fashion during a game against the Twins at Target Field in June 2010, and he hasn't pitched in the majors since.
