A Magnetic Resonance Imaging (MRI) exam taken on Mariners' left-hander Erik Bedard Tuesday afternoon showed there is nothing structurally wrong with the pitcher's left shoulder, and he will continue his current rehabilitation program. Bedard has been sidelined since July 4 with tightness in his left shoulder. The exam, taken and examined by Mariners' medical director Edward Khalfayan, confirmed the previous diagnosis of an internal impingement. "I was pretty encouraged by what I heard, and I think Erik was encouraged," interim Manager Jim Riggleman said after the Mariners' 4-2 loss to the Red Sox. "Whatever was found there, whatever terminology, my understanding is that Erik feels he will be able to get out there and start throwing again pretty soon. That's the hope." "I don't know when he'll throw again, throw to a catcher or just play catch, but we need him out there, and he wants to be out there. There are some things going on [in his shoulder] that is not allowing him to be free and easy. When he is, he'll be out there."
