Melbourne  - Tomas Berdych has joined Roger Federer in slamming the Hawk-Eye electronic linecalling system after its failure struck him at a key moment in his losing fourth-round match to the Swiss star at the Australian Open.

It's no secret that traditionalist Federer has never been a fan of the system - and his poor record on challenges proves that point.

But the system really caught Berdych at a bad time when it failed to function on a challenge he made - likely because of a deep shadow over one side of the court in late afternoon.

It seemed that Tomas Berdych would derail Roger Federer's run at a record 14th Grand Slam title for two sets at the Australian Open.

However, just then, a meltdown was experienced by the 6-foot-5 (1.96-meter) Czech, thus giving a chance to Federer to recover for a 4-6, 6-7 (4-7), 6-4, 6-4, 6-2 win Sunday. This marked only his fourth career comeback from two sets down - to reach the quarter finals.

Until Novak Djokovic took a 5-0 lead, he was not pushed, who then had to work all the way for a 6-1, 7-6 (7-1), 6-7 (5-7), 6-2 victory over 2006 runner-up Marcos Baghdatis of Cyprus.

Melbourne, jan. 23 : British tennis star Andy Murray has blasted rivals Roger Federer and Novak Djokovic and says the moaning pair are only putting pressure on themselves.

The Sun quoted Murray as saying that Federer keeps whinging about being continually asked about Murray's chances of winning the Australian Open.

Murray said: "A few players disagree that I have been made the favourite. There have been some quite big contradictions from both of them. By saying they should be the favourites, they are putting more pressure on themselves."

Melbourne  - Even ice-calm Roger Federer admits that his stress levels have eased in recent months as he slipped from tennis' top ranking.

Still ranked second, the Swiss star said that he feels an eerie calm as he pursues a fourth title in six years at the Australian Open.

"Maybe I'm a bit more relaxed," he said after passing the first round against Italy's Andreas Seppi. "When you're number one you put your head down, you try to win as many tournaments as possible."

Melbourne  - Roger Federer knows he's in tennis for the long haul, now expecting to figure in the sport well beyond the 2012 London Olympics.

With his immediate objective a fourth Australian Open title as the first Grand Slam of the season began on Monday, the 27-year-old has - as always - cast his eye well into the future.

"I want to do well not only this year but many more years to come," said the 13-time Grand Slam champion. "I don't feel like this year is my last chance to either win the French Open or pick up a few Slams more easily.

Melbourne  - Roger Federer was all business at the Australian Open player party, putting in a quick appearance before making an exit out the back door to return to his peace and tranquility prior to his Monday start.

The Swiss second seed was concentrating his energies on stopping first-round opponent Andreas Seppi, with little time for socializing.

Federer's pit stop at the Mexican restaurant in the Crown casino complex, where he has stayed for some years during the annual Grand Slam event, was as well-choreographed as his straight-set wins on court.
