ESPN is reporting Mike Pelfrey had MRI in New York this morning for general shoulder tightness. He's been cleared to start this weekend vs. Giants. I noticed him in these past two starts kind of hunching his shoulder after a couple of pitches as if he were trying to shake it loose. Most pitchers feel tightness especially this time of year, as the weather changes, spring going into summer. He was pitching good baseball until his last start. The Mets are taking no chances.
