Qualifier Olga Govortsova of Belarus was leading their second-round contest 6-0 and 2-1 when Poland's Radwanska, the Wimbledon runner-up, called it a day. Radwanska, who enjoyed a first-round bye, had received treatment on the shoulder after the first set.

Govortsova advanced to a quarter-final clash with Russian seventh seed Maria Kirilenko, who advanced on a walkover when Germany's Mona Barthel withdrew before their scheduled match with a stomach ailment.
