Maria Sharapova overcame Sabine Lisicki ,through to the fourth round

Maria Sharapova overcame Sabine Lisicki to set up a tasty fourth-round clash with Caroline Wozniacki at the US Open.

There was nothing pretty or straightforward about Sharapova's 6-2 6-4 victory, which took an hour and 41 minutes, but she was the tougher in the end under the lights on the Arthur Ashe Stadium court.

Lisicki had only won one of six previous meetings against Sharapova, at Wimbledon in 2012, but her big game means she is always a danger.

Last month the German hit a serve measured at 131mph, a world record for a woman.

The Russian was coming under pressure in every service game but resisted impressively, and another Lisicki double fault eventually handed her the set.Her radar was off in her first service game, though, with two double faults proving very costly as Sharapova ground her way into a 3-0 lead.
