Errani defeats out-of-sorts Kuznetsova

Italy's Sara Errani is through to the quarter-finals of a second successive grand slam after putting out former French Open champion Svetlana Kuznetsova today.

Errani, the 21st seed, was too consistent and too smart for 2009 winner Kuznetsova, who made far too many errors, particularly in the first set, before going down 6-0 7-5.
