Though Andy Oliver has been a starting pitcher for the vast majority of his Tigers tenure, he finished out last season in the bullpen at Triple-A Toledo. Dombrowski said the Tigers will most likely have him work out of the bullpen in Spring Training.
By contrast, Detroit plans on having fellow southpaw prospect Casey Crosby work as a starter in camp as long as they have the innings to stretch him out. Between Crosby's stuff and his history of injuries, he has been projected in the past as a relief candidate, but the Tigers aren't committing to that just yet.
The lone lefty assured of a bullpen spot is Phil Coke, who served as closer during the American League Championship Series and World Series. Darin Downs and Duane Below are among the candidates for the second lefty role, if the Tigers decide to carry one.
