He's ranked 25 in the race now so I don't know if it's possible.
Maybe if he wins Lyon and all other tournaments he has entered!
Anyway I'm not sure how much he wants to travel to China. That was great last year, how he qualified by winning the last tournament of the season and then surprising everybody reaching the Masters final but at least it was in Australia, like the Davis Cup final.
This year I think he'll be happy to get a rest and good practice for the Davis Cup and let Kafel and Marat tire themselves in Shanghai.
