The Red Sox bullpen has been one of they keys to their success so far this year, and really for the past couple of months it’s been a core group of six guys who have carried the load. Now, they’re going to be down a man in that core with a bit of a surprise injury. The team announced prior to Friday’s game against the Yankees that they are placing Hirokazu Sawamura on the 10-day injured list with right tricep inflammation. Phillips Valdez comes back up from Worcester to take Sawamura’s spot in the bullpen.
