Defending champion Roger Federer set up a semi-final against Marat Safin with a brilliant display against America's Andre Agassi at the Australian Open.
Four-time champion Agassi was outplayed by his younger opponent
Agassi, a four-time Australian Open champion, played some fine tennis but was simply out-gunned by Federer.
The Swiss world number one served superbly and the rest of his game matched up as he won 6-3 6-4 6-4.
Federer broke the Agassi serve in the opening games of each of the second and third sets as he powered to victory.
In the end it took Federer just one hour 39 minutes to dispose of Agassi's challenge and claim his 26th win in a row.
Federer said it was his serve that had made the difference after pounding down 22 aces on his way to victory.
"A good start always helps, especially against Andre and I think I really served well, he never broke me," said Federer.
"From the baseline it was clear who was the better man, so I had to serve better."
Agassi paid handsome tribute to Federer.
"He does everything well and a lot of things great. He just outplayed me," said the 34-year-old American.
"I wasn't picking his serve up well. You give a guy like that a lead and he can stretch it pretty quick.
"He was too good. I would suggest to his next opponent that he doesn't look to me for advice."
Agassi went for his shots throughout as he tried to unsettle the ice-cool Swiss but in the end he did not have the weapons to hurt Federer, and may have now played his final match at the Australian Open.
Agassi tried to force the pace from the start but once he was broken in the sixth game he was never ahead.
The shaven-headed shot-maker from Las Vegas battled bravely as Federer served for the first set but he could not take any of the three break points he managed to earn.
Federer took the set at the fourth time of asking, and when he immediately broke Agassi in the first game of the second set the writing was on the wall.
The young Swiss star has the complete game and at times he touched the heights as he dismantled Agassi's challenge.
When he claimed Agassi's serve at the start of the third set the crowd feared Agassi would be swept aside.
Despite Agassi's age his desire is undimmed and he pushed Federer all the way, but there was only ever going to be one winner under the lights in Melbourne.
