Mets placed LHP Jon Niese on the 15-day disabled list, retroactive to July 5, with a left shoulder injury. Niese left his last outing after being hit in the back by a line drive, but it's his shoulder that's sending him to the DL. The left-hander has seen his velocity drop in recent starts and might be dealing with fatigue. Niese will surely undergo an MRI and/or other exams before it's determined how long he might be out.
