despite what results say I think grass could one of his best surfaces : usually
he has time on the ball, he can hit in advance without any problems, doesn't have any problem to hit a backspin ball and his serve is improved a lot. I remember when two years ago he played an amazing match against youzhny (when the russian was very strong
) that endend only at the 5th set.
But we will see, lately he's putting his weight behind during the moment to hit the ball, he lost punch and some of his natural equilibrium during cross court rallies. Of course everything depends by this bad shape he got this whole year...
but it's time to change, to be back at last year
hopefully he will like green more then red like color
