Petra Kvitova is not usually a name you'd associate with Australian Open success but in her side of the draw, where Agnieszka Radwanska is, she came out as the top player based on the head-to-head.
I would've picked Aga, because of her recent win at the year-end championships but sometimes the head-to-head comes statistically correct.
Petra has her hands full though as her prospective opponents include the up-and-coming Daria Gavrilova, former finalist Dominika Cibulkova, the wily Andrea Petkovic and former US Open champion Samantha Stosur. Then Serena looms in the semifinals.
Well, it would be interesting to see if Petra finally breaks through this year, in the other grand slams and not only at Wimbledon.
