That is based on 52 weeks. Most of his points will drop down this fall during indoors season. When he comes back in 2010 he will have 665 points and will be ranked somewhere at 80-100th place.
He won Stockholm, made a 1000 Final, and a few smaller tournament F's and semi's. A few other early round exits at 1000's and grand slams make him the 14th best player in the world right now!?
