Dominika Cibulkova vs. Agnieszka Radwanska
Agnieszka seems to have recovered from her injury which was hampering her in Indian Wells. She will be out for revenge against Cibulkova, who upset her in the semi-finals of Melbourne. Cibulkova subdued a resurgent Venus Williams, and is just one win away from the top 10. She will be confident of her chance against Radwanska, but I think the Pole just had an off day in Melbourne. If Agnieszka is healthy and plays to her normal standard, she should be able to win this.
Pick: Radwanska in 2 sets
Caroline Wozniacki vs. Li Na
Destroying Sloane Stephens ought to give Caroline Wozniacki a much needed confidence boost. However, the American was just horrid in her match and Li is a much tougher opponent. Caroline's game is just too reactive to make a dent on Li's aggressive game. If the Chinese hits her spots, Wozniacki can provide little resistance. Well, it's an achievement for Caroline to reach the quarter-finals, but this should be where her journey ends.
Pick: Li in 2 sets
