Ferrer too strong for Chardy

David Ferrer booked his place in the fourth round of a grand slam for the 15th time in succession after a straight-sets win over Jeremy Chardy at the Australian Open.

Ferrer, the No 3 seed, defied the searing Melbourne heat to down the Frenchman 6-2 7-6 (7-5) 6-2 in two hours 12 minutes

The Spaniard will now face Florian Mayer, a 7-5 6-2 6-2 winner over 20th seed Jerzy Janowicz, in the last 16, with Ferrer boasting a 4-3 winning record against the world No 37.

And Ferrer was delighted to have extended his record in the grand slam.

"I am very proud of that, I like to play consistent and over the last four to five years I have been getting some good results," Ferrer said.

"I was relieved to win the second set, it was a miracle because I was a lot of set points down and after winning the second set I played more relaxed and felt better."

Seventh seed Tomas Berdych has joined Ferrer in the fourth round after a straight-sets victory over Damir Dzumhur.

Berdych needed an hour and 45 minutes to brush aside the Bosnian 6-4 6-2 6-2.

Kevin Anderson, the 19th seed from South Africa, recovered from two sets down to beat Edouard Roger-Vasselin 3-6 4-6 6-3 7-6 (7-5) 7-5.
