Eric Gagne could be pitching in Dodgers games in as little as six weeks after undergoing a relatively minor operation on Friday morning to remove a sensory nerve in his right arm. An upbeat Dr. Frank Jobe, who assisted Dr. Ralph Gambardella, said nothing structurally changed in Gagne's elbow and the procedure, which took "30 minutes or less," went smoothly. "I think it's good news," said Jobe. "He'll begin throwing a ball in three weeks, and in six weeks, get in a game. Those are guesses, a week one way or the other. I don't think it will be longer than six to eight weeks."
