Wednesday's weather: Cloudy and cool with sunny breaks. High of 74 degrees.
• Venus Williams digs deep. After raising eyebrows with her latest fashion statement -- the Associated Press called it a "revealing peek-a-boo lattice-style top with a multicolored satiny short skirt" -- Williams made an even bigger impression with her gutsy performance against Sandra Zahlavova. The 30-year-old American suffered a muscle injury on the final point of the first-set tiebreak and appeared in agony during a 10-minute medical timeout between sets. Naturally, she won the next set at love before coasting to the 6-7(6), 6-0, 6-4 victory.
• More disappointment for the Americans. After three days, Venus is the lone Yank remaining in the women's draw. Just four American men remain after virus-stricken Mardy Fish's come-from-ahead loss to Tommy Robredo.
• The upsets that didn't happen. Second-seeded Roger Federer held a two-sets-to-none lead over Gilles Simon, but was pushed to the limit in a 6-2, 6-3, 4-6, 4-6, 6-3 victory. Earlier, No. 9 seed Fernando Verdasco rallied from two sets down to beat chronic giant-killer Janko Tipseravic, who was unable to capitalize on three match points in the fourth.
• Top seeds march on. Many doubt Caroline Wozniacki's claim to the top ranking, but she's played like a No. 1 so far. With her 6-1, 6-0 victory over American Vania King, Wozniacki has dropped just eight games through two rounds. Other women's winners included No. 6 Francesca Schiavone, No. 8 Victoria Azarenka, No. 9 Li Na, No. 11 Justine Henin and No. 14 Maria Sharapova, with No. 3 Novak Djokovic, No. 6 Tomas Berdych and No. 12 Gael Monfils among the men to advance.

They Said It
"The outfit is inspired by Alice in Wonderland. It's kind of about a surprise, because when Alice goes down the rabbit hole, she finds all these things that are so surprising. This outfit is about having a surprise in tennis a dress, and showing some skin and then just having a print. Prints don't happen that often in tennis. So it's called the Wonderland dress."
--Venus Williams, on her much-talked-about outfit after Wednesday's victory
