Volandri only played 3 mtahces on hard. The ones he lost were against calleri and Ferrero and the game he won was against Kiefer. Not so bad.
At the end of last year he did very bad on the hard courts but that was because he was playing with a back injury, he just wanted to play to try and get his rankings higher.
I admit that Sargsian is better on grass but Volandri who I saw at Wimbledon last year had the potential on grass, he played some points but his incosistency kills him on grass. One thing you need to be on grass is consistent otherwise you will go downhill fast.
Thats what i thought, his serve on grass is so funny, his serve on any surface is quite funny. Thats the one thing he will need to improve if he wants to reach the top 20 which the rest of his game has the potential to do. He is even a good player at the net.
