Worth is a career minor-leaguer in the Tigers system; an infielder, he was beginning his fourth season at Triple-A Toledo. Don Kelly played left field in Young’s place on Friday night, and Jim Leyland will likely use Kelly, along with Brennan Boesch and Andy Dirks, to fill in until Young’s status is clear.
Players on the restricted list don’t count against 25- or 40-man roster limits and don’t get service time while they’re on the list. Depending on the situation, they can be paid, or not paid; that’s generally subject to negotiation between the team and the MLBPA.
