NEW YORK -- Since making one rehab assignment appearance for Triple-A Louisville, Reds reliever Bill Bray has been in Arizona working at extended spring training. Bray, who is on the disabled list with a strained left groin, has compounded his situation with back soreness. "We're trying to get him through that," Reds general manager Walt Jocketty said. "His mechanics got out of whack because of the [groin] injury. Now he's having problems with his lower back." Jocketty did not have an expected timetable for Bray's return.
