Defending champion Serena Williams and four other past winners, including her sister Venus and wild-card entry Kim Clijsters, head the women's field for the US Open. Ninety-nine of the top 100 women in the current WTA rankings received direct entry Thursday into the hard-court Grand Slam tournament, played Aug. 31 to Sept. 13 in New York. The one missing is No. 88 Nathalie Dechy of France, who announced her retirement this week. Serena Williams will be bidding for her fourth US Open championship and third major title of 2009. Clijsters will be playing at Flushing Meadows for the first time since winning her only major title at the 2005 US Open. She is making a comeback after retiring in 2007. Dinara Safina is atop the list of 104 direct entries. They'll be joined in the 128-player field by the eight women (including Clijsters) who receive wild cards and the 16 who will earn berths in Aug. 25-28 qualifying.

Sharapova ‘100 percent' Maria Sharapova declared her surgically repaired right shoulder fully healed and that she was ready to return to the court for the first time since a disappointing performance at Wimbledon. “I am a hundred percent,” Sharapova said Wednesday before making an appearance for the Newport Beach Breakers in their World Team Tennis match against Kansas City. “I mean, if I wasn't at that point, I certainly wouldn't be playing. That's why I took my time and gave myself a chance to really go out there and to feel like I didn't have any excuses.”
