Federer, Nadal ease through

Roger Federer and Rafael Nadal have eased into the third round of the Australian Open after convincing victories.

Top seed Nadal moved through the gears as he blew away the overmatched Thanasi Kokkinakis 6-2 6-4 6-2 on Rod Laver Arena.

And at the same time Federer, ranked sixth for the tournament, powered past Blaz Kavcic to record a 6-2 6-1 7-6 (7-4) victory on Hisense Arena.

Federer broke Kavcic six times in the first two sets as he moved into a commanding lead, before he took his foot off the gas against the Slovenian.

Kavcic enjoyed his best spell on the match in the third set but although he held serve to force the tie-break it only delayed the inevitable - with Federer securing victory in 103 minutes.

Nadal needed 10 minutes more to take care of Kokkinakis - with the former Australian Open and US Open junior finalist putting in a determined display.

And Nadal was full of praise of the 17-year-old, saying: "He has fantastic potential, with a great serve and a great forehand. He has all the ingredients to be a fantastic player so I wish him all the best."

Advantage

Former Melbourne finalist Jo-Wilfried Tsonga avoided a potential banana skin as he beat Thomaz Bellucci in straight sets.

The 10th seed registered a 7-6 (8-6) 6-4 6-4 victory under the roof of the Hisense Arena - with Tsonga making the most of the conditions as the temperatures rose outside.

"I think it was an advantage for me to play in these conditions," Tsonga said. "It was great for me but not for my opponent.

"He played qualies (qualifying) and he had a tough match two days ago, while I just played one match and that's it. It makes a difference."

Kei Nishikori, the 16th seed, needed just one hour 49 minutes to overcome Dusan Lajovic 6-1 6-1 7-6 (7-3).

However Andreas Seppi crashed out after another five-set epic. The 24th seed had dug deep to beat Lleyton Hewitt in the opening round but he was ousted 6-4 2-6 6-3 4-6 7-5 by Donald Young.
