Italy vs Argentina = Clay Court
Czech Republic vs France = Indoor Hard Court
Serbia vs Great Britain = Clay Court
USA vs Croatia = Hard Court
My pick
Lukas Rosol vs Tsonga = Jo-Wilfried Tsonga @ 1.18
Jack Sock vs Marin Cilic = Marin Cilic @ 1.50
Cilic form is quite unstable on Atp Tour but he always done pretty nice job in major tournament as we already saw in last Wimbledon , he almost beating Roger Federer in quarter final
Toto Parlay @ 1.83
shame that murray and djokovic won't play
think that this match will be very interesting
I have been seeing matches of federer and nadal after that i dont got much knowledge about other players, but after seeing your all experience will try to bet on your prediction, but i think jack sock can give some tough competition and int this match jack sock will win one set ,
