Grabow initially planned to have minor surgery after the 2007 season to remove bone chips in his left elbow. But after receiving a cortisone shot in August, he changed his mind. "I've been symptom-free for the past few weeks", Grabow said. "I want to see what my options are. I don't think I'll really need to have surgery. Maybe I can manage it, and pitch through it." He had his left elbow examined by Los Angeles Angels orthopedist Lewis Yocum, who suggested that rest would be an effective alternative to arthroscopic surgery. Grabow then decided against surgery, and instead followed a program of rest and rehabilitation, extending his period of rest from three to eight weeks, and concentrating his workouts more on strengthening his legs and shoulders.
