Orioles reliever Danys Baez informed team officials yesterday that he has decided to have surgery to repair a partially torn ligament in his right elbow. Baez, who started the season as the Orioles' top setup man but struggled mightily after a solid April, still hasn't set a date or chosen a doctor for the surgery, but it will force him to miss next season, joining closer Chris Ray on the sideline. "We feel that's clearly the right course of action with the information that we have," Orioles president of baseball operations Andy MacPhail said about Baez's decision to have the surgery.
