Carlos Delgado, who signed a minor-league deal with the Red Sox last month, has a tear in his left hip and his comeback this season is over. Delgado, who was seen by Dr. Marc Phillipon on Wednesday in Vail, Colo., is expected to rejoin Triple-A Pawtucket and begin reviewing treatment options. "He's extremely disappointed," Delgado's agent David Sloane said. "It would be tough for a human being to not be disappointed. He wouldn't be human if he wasn't very upset about it." Delgado, 38, hasn't played in the majors since May 2009 after undergoing two surgeries on his right hip.
