The Marlins didn't have a chance to get excited about Logan Morrison and Joe Mahoney beginning rehab assignments with Jupiter Monday. Before they took the field, they announced another player was head to the disabled list. Matt Diaz is the 11th Marlin currently on the shelf (13th this season). Earlier this month he suffered a bone bruise to his left knee. The Marlins limited him to pinch-hitting duty, but without the needed rest it wasn't improving.
