Swiss Grand Slam master Federer was stung into action after losing the first set to reel in Italian Simone Bolelli in four sets and take his place in the seeded round. Murray, a three-time runner-up in Melbourne, extended his record against Australian opponents to 10-0 with a consummate straight sets victory over Marinko Matosevic.

Elsewhere, 10th seed Grigor Dimitrov overcame Lukas Lacko in four sets and seventh seed Tomas Berdych accounted for Jurgen Melzer. World number three Rafael Nadal was bidding to join them in his night match against American qualifier Tim Smyczek on Rod Laver Arena.

Second seed Federer, chasing his fifth Australian Open title, problem-solved his way to a 3-6, 6-3, 6-2, 6-2 win over Bolelli and will play another Italian Andreas Seppi in the third round.

The 17-time Swiss Grand Slam champion, who developed a mystery swollen finger during the contest, lost the opening set after the only break on his serve, but he found a solution and swept through the next three sets.

"It's always a good feeling fighting your way out of a match, winning the last three sets convincingly and actually playing really positive tennis," Federer said.

"Today I had to do some adjustments because he was doing things very well. By figuring things out it's a great feeling to have once you've got it."

Federer has always made the third round in 16 attempts in Melbourne and has reached the semi-final stage for the last 11 Australian Opens. The Swiss legend was non-plussed by a swollen finger that may have been caused by a bee sting.

"It's the weirdest thing. I don't know. I feel it on the tip of my finger. I feel like it's numb and swollen," he said.

- Momentum building -

Murray got some payback on vocal local hope Matosevic as he cruised into the third round. The British sixth seed had few problems in winning 6-1, 6-3, 6-2 in 1hr 42min and will next face Portugal's Joao Sousa.

It was also some riposte for Murray after Matosevic criticised the surprise appointment of Amelie Mauresmo as his coach last year. Matosevic created headlines back then when he dismissively said of Murray's decision to replace Ivan Lendl with Mauresmo: "I couldn’t do it because I don’t think that highly of the women’s game."

Bulgaria's Dimitrov reached the third round after downing Lacko 6-3, 6-7 (10/12), 6-3, 6-3 and will now play former finalist Marcos Baghdatis. "Lukas moves all around the court pretty well. He played a really good second set," Dimitrov said.

"After that I had a good momentum throughout the whole match. I think I was in control ever since that set." Big-serving Czech Berdych, who this week announced his engagement to model girlfriend Ester Satorova, is happy the way things are progressing with his Open campaign.

"Everything is going well. There were a couple of changes for me in my team at the end of last season," Berdych said. "I'm having a good run so far, two wins, and looking forward to adding some more."

Rising Australian younger Nick Kyrgios advanced with a four-set win over big-serving Ivo Karlovic.
