Williams sisters downed in doubles

Defending champions Venus and Serena Williams were knocked out of the women's doubles quarterfinals at Wimbledon on Wednesday, piling on the misery for Venus.

While Serena progressed to the singles semifinals on Tuesday, five-time Wimbledon champion Venus was knocked out by Tsvetana Pironkova.

Winning the doubles title would have given Venus at least something to remember this year's Wimbledon by.
