Bill Bray has been sent back to the Nationals' spring training complex to rehab a sore left shoulder. Bray reported to Double-A Harrisburg on May 6 after spending the first five weeks of the 2013 regular season recovering from lingering back and groin problems. And now he's back in Viera, Florida because of a shoulder issue. "It's working its way out," the veteran reliever told Andrew Simon of MLB.com on Wednesday.
