Petra Kvitova vs. Maria Kirilenko
Kirilenko wil attempt to beat Petra for the 2nd consecutive time after upsetting her in the important Olympics. Maria is coming off an impressive win over Radwanska and will be very confident of her chances. However, that match was gruelling and Kvitova will be the fresher one. After struggling with form the whole week, Kvitova showed what she's capable of by demolishing Klara Zakopalova. Given the slow conditions of the court, it might favour Kirilenko, but if Petra is patient enough, she can come to the net to knock some winners of it.
Pick: Kvitova in 3 sets
Sara Errani, the ever pesky player, confirms her top 10 spot with a win over Marion Bartoli. However, there's always a player who they just cannot defeat. Errani's nightmare is Maria Sharapova. Sharapova's deep and penetrating groundstrokes went away in her 4th round match's first set. But once it's back, she was absolutely untouchable. Sara won't stand a chance against the relentless ball bashing of the tall Russian.
Pick: Sharapova in 2 easy sets
