World tennis number three Venus Williams has followed her sister Serena out of the Madrid Open when she was beaten in 3 sets by unseeded Russian teenager Alisa Kleybanova in the second round.
The American was broken seven times by the 19-year-old world number 26 from Moscow, a day after Serena retired from her first round match against Francesca Schiavone with a knee injury.
Kleybanova knocked Ana Ivanovic out of this year's Australian Open.
