Petra Kvitova's shock defeat to Jelena Jankovic

Defending champion Petra Kvitova was shocked by Jelena Jankovic at Wimbledon.

It marked the first time since 2009 that two-time Wimbledon winner Kvitova, 25, has failed to make at least the quarter-finals at the All England Club.

Jankovic, the 28th seed, beat the Czech world number two 3-6 7-5 6-4.
