Anderson ousted by Berdych

Berdych, who was in the driving seat the entire match, powered his way to a 6-2, 6-2, 6-3 victory over Anderson in a match that lasted one hour and 58 minutes.

The pair have previously met on nine occasions during the last two years - including at the Australian Open in 2012 and 2013 - where Berdych came out on top in all nine matches.

Anderson got off to a great start in Melbourne, scraping through the first round, beating Czech Republic's 82nd-ranked Jiri Vesely 2-6, 6-7 (4/7), 6-4, 6-4, 6-4, in his opening match.

He then beat Austria's Dominic Thiem 6-4, 6-3, 6-4, securing his passage to the next round of the tournament.

In the third round, the big-serving South African put up a brave performance, beating Edouard Roger-Vasselin of France 3-6, 4-6, 6-3, 7-6 (7/5) 7-5.

Berdych will next face Spain’s David Ferrer in the quarter-finals.
