Jelena Jankovic retires from fourth-round match at Wimbledon

Serbia's Jelena Jankovic became the biggest casualty of the women's singles so far at Wimbledon when she retired at 6-1 3-0 down to Russian Vera Zvonareva in the fourth round on Monday. 

The fourth seed received treatment for an injury to her back and looked ill at ease throughout the match in the glorious sunshine on Court 12.   

Zvonareva raced to the opening set in 24 minutes and claimed two breaks in the second when Jankovic had a medical timeout.

She returned for three more points before strolling to the net and offering her hand after 43 minutes of play.

Zvonareva, the 21st seed, will now play the winner of the all-Belgian fourth-round clash between Kim Clijsters and Justine Henin for a place in the semi-finals.
