Sara will fight to avoid the double bagel against Vika
She has nothing to hurt her and Vika will hit so many ROS winners
Radwanska and Kerber are great players, but nothing that average Azarenka hasn't beaten before in straight sets. She knows their level and their game well.
Sam, Bartoli and Petra are completely unpredictable. They can be awful or play superb attacking tennis and beat most top players, including Vika. That's why Vika has the easier draw in my opinion
