Lekha, thanks for starting the thread
Hope Roger is healthy, that's the most important thing
Difficult group for Roger to have all the players in his half who have beaten him this season. We have seen how dangerous Muzza is for Roger and although Roger has a comfortable h2h against Roddick we should never underestimate him. Beside the fact that he has beaten Roger this year (well, that was the case with several players
), we shouldn't forget that he had MP's against him 2 years ago in their encounter in Shanghai. Simon had a great season and nothing to lose in the Masters Cup. It's good that Roger has played against him, so that he knows now what to expect from him.
Good luck for the tournament Roger
