Since the fourth inning last Friday, when Jacoby Ellsbury had his right shoulder crunched under the weight of Tampa Bay Rays shortstop Reid Brignac, the Red Sox have held out hope that their Gold Glove center fielder wouldn't require surgery. Yesterday, they finally were able to uncross their fingers. The results of Ellsbury's MRI exam were sent to Los Angeles and reviewed by orthopedic surgeon Dr. Lewis Yocum, who concurred with the Sox medical staff's diagnosis of a shoulder subluxation, or partial dislocation.
