 Roger set a World Record  today while  playing his 1000th Match against Petor which raced him to the Semi Finals.

 Roger reached 21st consecutive quarter final of a Gran slam .

His Tennis journey started in 1998 to Melbourne in 2012. He faced  lot of pains and joy in this  long spell.

 Roger today  brushed aside the challenge of Argentina's Potro in straight sets  to become the first man through to the Australian Open semifinals.

Federer, who always looked in control, won 6-4, 6-3, 6-2 on a sun-drenched Rod Laver Arena and will next face either long-time rival Rafael Nadal or Czech Tomas Berdych.

In a rematch of the 2009 US Open final won by the Argentine, the third seed started in ominous fashion, unveiling his full repertoire of strokes and breaking del Potro at his first opportunity.

"I'm very happy," Federer said. "I thought it was a great match. It was tough with the sun and shade creeping across the court but I thought we did well. I thought it was a high-quality match."

Federer said he was aware of the dangers posed by the 6ft 6ins (198 cm) tall  Potro but said he was "able to maneuver him around" the court.

He said he would probably tune in to watch the later semi-final between Nadal and Berdych, even though he knew the games of both well.

"There are no secrets out there but I will still enjoy it. I love good tennis," he said.

Victory for 16-time grand slam winner Federer, who has not yet dropped a set -- although he had a walkover in the second round -- means he advances to his 30th grand slam semifinal, just one behind Jimmy Connors on the all-time list.

The Swiss is chasing his first major since his Australian Open triumph in 2010 after failing to win a grand slam last year for the first time since he captured his first, at Wimbledon in 2003.
