German 10th seed Angelique Kerber has been knocked out of Wimbledon in the third round by unseeded Spanish youngster Garbine Muguruza.

Muguruza, 21, took the victory in three sets by a score of 7-6(12) 1-6 6-2 in two hours and 37 minutes.

Kerber had chances to break and take an otherwise close first set, but her comparatively inexperienced opponent showed resilience to take it to a tie-break.

There was little to separate the duo in the decider, with Muguruza eventually taking it 14-12 to seal the first set in one hour and 25 minutes.

Kerber showed her class in the second set though, racing into an early lead and then breaking again to take the set 6-1.

However, Muguruza reeled off a break of her own early in the third, and despite sustained pressure from Kerber, she held on to advance to the fourth round.
