World number one Ana Ivanovic’s luck finally ran out at Wimbledon on Friday when she was toppled 6-1 6-4 in the third round by China’s Zheng Jie.

Forty-eight hours after the Serb saved two match points against Nathalie Dechy, the second with the help of a netcord, she suffered an astonishing meltdown on Court One.

The French Open champion struggled to keep the ball in play as she either sprayed errors off the court or scooped shots into the net with alarming regularity.

The 133rd-ranked Zheng could hardly believe her eyes when Ivanovic shovelled a service return into the net to gift her the first set in 30 minutes.

It was all over 42 minutes later when Ivanovic miscued a shot high into the sky on match point.
