Serena Williams vs. Venus Williams
As expected, Serena struggled but eventually subdued Caroline Wozniacki. Can she escape against her sister, Venus Williams? The elder sister has been inspirational throughout the week, fighting her heart out on the court. She knows her smaller sister's game inside out, so that is an advantage that the other players don't have. However, yet another draining 3 setter will definitely put Venus at a disadvantage. Serena always plays her best in big matches, and this is as big as it gets. Venus might pull a set off, but Serena will steady the ship eventually.
Pick: Serena in 3 sets
Agnieszka Radwanska vs. Ekaterina Makarova
A surprise semi-final appearance for Makarova here, and she will like her chances against Radwanska. The Russian won their last 2 matches, including a hammering in Wimbledon just 2 months ago. Nevertheless, Radwanska seems to be back in her groove as evidenced by her dismantling of Azarenka. I believe this should be a close match, with Makarova nervous at the prospect of entering a Premier final. I'm going to go with my heart and pick Makarova to cause an upset here to reach her first Premier final.
Pick: Makarova in 3 tight sets
