Did anybody watched his matches after AO? I can only see the score of his matches. Either he wins or he loses, it always 7/6, 7/5 or 6/4. (Well, only second set against Roddick was 6/2) I mean all matches look pretty tight. But if you have such score in all your matches, independently of who is your opponent, it's strange. Does he try something new to his game? Does he lack something in his own game? Physcally? Mentally?
