Fourth seed Alexander Zverev survived an injury scare and an epic third-set tiebreak to beat Britain's Cameron Norrie and match his best Wimbledon run by reaching the fourth round for the third time on Saturday.

The German produced a sensational display of serving to win 6-4 6-4 7-6(15) - finally ending Norrie's rugged resistance by converting his sixth match point under the Centre Court roof.

Zverev, 27, dropped only two points on serve in the third set, although one of them was a double-fault that gave Norrie an early advantage in what proved to be a gripping tiebreak.
