Stosur over Li(Stosur is in better form, better clay court play and has the H2H advantage)
Wozniacki over Sharapova(Sharapova is just too error prone for this matchup vs the wall)
Nadal over Gasquet(Obvious. Gasquet is out of gas and can't beat Nadal anyways)
Djokovic over Murray(Djokovic made Murray his bitch in AO finals. This court suits him even more)
Wozniacki vs Stosur
Nadal vs Djokovic
If there's one upset, I'd say Li maybe wins due to Stosur playing like a WTA player.
