'Crip walk' repeat for Serena?

Will Serena Williams dance at the US Open? The Olympic singles champion isn't sure.
Williams caused a stir with her celebratory "crip walk" dance when she beat Maria Sharapova at the Olympics this month, but has nothing planned if she wins next month's Open. She says the first dance was impromptu. She adds: "I have to win seven matches, so we'll see."
The Wimbledon champ joined fellow tennis players Victoria Azarenka, the Bryan Brothers and James Blake at Thursday's annual Taste of Tennis, where top chefs provide culinary delights in an event for charity. Blake brought his infant daughter, who was cradled by Williams.
Williams says she's still on an Olympics high. She says she and sister Venus plan to be in Rio de Janeiro for the next Summer Games.
The Williams sisters also received a wild-card entry into the US Open doubles draw Friday, giving them a chance to play for their 14th career Grand Slam title.
The sisters won Wimbledon, then followed with a gold medal at the London Olympics and will now try for their first US Open championship since 2009.
Also receiving a wild card was three-time singles champion Kim Clijsters, who is playing in what she says will be her last tournament. She's paired with another Belgian, Kirsten Flipkens.
NCAA champions Mallory Burdette and Nicole Gibbs got a wild card, as did American Melanie Oudin, who will team with Grace Min.
Ryan Harrison and his younger brother, Christian, were among the men to receive doubles wild cards.
