Andy Roddick swept into the quarter-finals of the Australian Open after a phenomenal display of power against Sjeng Schalken. The world number one is yet to drop a set in the tournament and that record never looked in danger from the moment he broke at the first attempt.
Roddick wrapped up the opening set in 18 minutes before racing to a 6-1 6-2 6-3 victory in just over an hour.
The 21-year-old will now play Marat Safin, who saw off James Blake.
Roddick hit 14 aces against Schalken, one to save the only break point against him, and 27 winners. "That's probably the best I've hit the ball from the back of the court in a while," Roddick said.
"I served well today, that was one of the keys.
"I feel like I'm getting better with each match out there and I felt really good from the baseline today."
Roddick admits there is no room for a dip in form, as the quality of the field still left in the tournament is very high.
He said: "I can't remember the last time in a Slam where you had this many big names and pre-tournament favourites still battling out this late in the second week.
"As a fan of tennis, it's pretty exciting - I'm looking forward to getting out there."
And of all the big names, Roddick believes Andre Agassi is the man to beat.
"I think it's Andre's title until someone takes it away from him," he said.
