I'm with Ivanovic in this match, but unfortunetely she's too weak to beat Serena, but of course I wish her luck, maybe it'll be surprise and she'll take a set.
Nole will win easily
I think very interesting will be also Pavyluchenkova - Schiavone, both have chances to win.
Wozniacki - Kuznetsova, hmm I think Carolina won't have big problems to beat Svetlana.
and Petkovic - Suarez Navarro, I bet Andrea as the winner of this match, she's in quite a good shape in this tournament.
