Roger Federer eased through his toughest test at the Australian Open so far with a comfortable victory over Tomas Berdych.
The former world No. 1 and four-time champion at Melbourne Park took on the 10th seed in the final night match on the Rod Laver Arena and was in scintillating form.
After six months out through injury, many thought this would prove to be a real test but, in truth, Berdych never got near the Swiss as he was beaten 6-2 6-4 6-4.
Federer, who served brilliantly throughout, will now go on to face Kei Nishikori in the fourth round after the Japanese beat Lukas Lacko 6-4 6-4 6-4.
Federer started the better of the two, breaking for a 3-2 lead in the opening exchanges.
A kind net-cord saw the Swiss secure a double break and the 35-year-old made no mistake in serving it out for 6-2.
The 17-time Grand Slam champion broke in the opening game of the second set and continued to bring out some masterful shotmaking before finishing it at 6-4.
Federer, the world No. 17, broke again at the same point in the third set and never looked back.
