New York Mets left-hander Jonathon Niese has been diagnosed with a partially torn rotator cuff, although surgery is not immediately recommended, assistant general manager John Ricco said. The diagnosis came after Niese was examined by team doctor David Altchek on Friday at the Hospital for Special Surgery in Manhattan. Niese had departed a start on Thursday in Atlanta in the fourth inning after experiencing pain in his pitching shoulder and a drop in velocity while pitching to Tyler Pastornicky. The southpaw landed on the disabled list Friday. The Mets called up submariner Greg Burke to take Niese's roster spot. Source: ESPN
