Tom Glavine has grown impatient with his sore left shoulder, and may retire if it doesn't improve within the next few weeks. "I'm willing to put in a little more time but I'm not willing to put in another six weeks or eight weeks because by then, you know what, I'm going to have to start all over again and I'm not interested in doing that," Glavine told the Associated Press. Dr. James Andrews advised that Glavine rest for at least two weeks after inflammation was found in his left rotator cuff.
