The Czech seventh seed powered past seeded South African Kevin Anderson 6-2, 6-2, 6-3 in just under two hours to set up a quarter-final with Spain's world number three David Ferrer.

Berdych maintained his impressive serving which, for the fourth match at the tournament, was not broken once -- a run of 53 service games.

It is Berdych's fourth straight quarter-final at the Australian Open and it is the only Slam where he has yet to reach the semi-finals. He trails Ferrer 4-7 in their meetings.

"I have a good memories from last season. We played twice, in Bercy and in London," Berdych said.

"I beat him in London and the week before in Paris Bercy, I was very close. I lost to him in three sets. So I'm going to have a plan and I hope it's going to be the right one."
