After last night's exhilarating action, we've got some great tennis to follow up.
At 11am, Justine Henin plays at Ashe while Novak Djokovic plays at Louis Armstrong. In the afternoon, Ana Ivanovic, Tim Henman, Marion Bartoli and Serena Williams all play.
Lleyton Hewitt will play on Louis Armstrong at night, while Venus Williams and the injured Rafael Nadal play at Ashe.
Match to watch for: Mardy Fish v. Tommy Robredo at 1pm on Ashe. Fish is hot and he gets the big stage to take on the nunmber 8 player in the world. A solid chance for a major upset.
