Novak Djokovic survives Tomas Berdych test

Novak Djokovic has defeated Tomas Berdych in straight sets to progress through to the semi-finals at Wimbledon.

The world number one was tested by the Czech during the first two sets, before moving on to seal a 7-6 6-4 6-3 triumph.

The opening set was dominated by serve, but despite falling behind in the resulting tie-breaker, Djokovic stormed back to take the final three points to earn a set advantage.

Berdych stunned his opponent with two breaks of serve at the start of the second, but Djokovic produced some scintillating play to take six out of the next seven games to move closer to the semi-finals.

The 26-year-old Serbian player stole an early break at the beginning of the third, and that proved enough to take his place in the last four, where he will play Juan Martin del Potro.
