Leasure was placed on the 15-day injured list with a right shoulder impingement Saturday, retroactive to July 17, LaMond Pope of the Chicago Tribune reports.
Leasure last appeared in a game Sunday when he gave up four runs on four hits and a walk over one inning against the Pirates. He'll now be forced to miss at least 15 days. In a corresponding move, left-hander Sammy Peralta was recalled from Triple-A Charlotte.
