Although "tennis whites" are no longer a requirement for either men or women on most courts, I still love tennis skirts and dresses. Putting on the right gear is half the fun for me (as I know it is for Venus and Serena Williams.) So, who is still in the running after the fourth round of women's singles matches? Elena Dementieva (Russia), Jelena Jankovic (Serbia), Sybille Bammer (Austria), Patty Schnyder (Switzerland), Flavia Pennetta (Italy), and Dinara Safina (Russia). Fourth-round play scheduled for today: Venus Williams (USA) versus Agnieszka Radwanska (Poland), and Serena Williams (USA) versus Severine Bremond (France). Both Venus and Serena Williams will play their fourth round matches today, Monday, September 1, 2008.
