Petra Kvitova's reign as Wimbledon champion came to a shock end on Saturday as Jelena Jankovic staged a superb fightback to claim a 3-6, 7-5, 6-4 third round victory. Kvitova's exit marks the first time since 2009 that the two-time Wimbledon winner has failed to make at least the quarterfinals at the All England Club. Jankovic looked down and out when she trailed by a set and was 4-2 down in the second against the Czech world number two.
