Top seed Novak Djokovic has had to rally to overcome a minor glitch against Czech Radek Stepanek in the third round at Wimbledon.

Stepanek broke Djokovic's serve to take the first set, before the Serbian eased to the next three sets 6-2, 6-2, 6-2.

The defending champion says he wasn't surprised by the way his opponent started.

He says Stepanek was out there to win a match, but he fought back well.

Novak Djokovic takes on fellow Serb Viktor Troicki in the fourth round.

In the women's, Agnieska Radwanska and Maria Sharapova have breezed into the fourth round while Kim Clijsters is also through after Vera Zvonareva had to retire hurt with health issues.

Kiwi Marina Erakovic is through to the third round of the doubles with her Thai partner Tamarine Tanasugarn.
