Melbourne: Rafael Nadal stormed past Croatia`s Marin Cilic into the Australian Open quarter-finals in his bid to unite the Grand Slam titles, as Kim Clijsters and Andy Murray also went through.
World number one Nadal was in devastating touch against the 15th seed, who struggled throughout and double-faulted on match-point to go down 6-2, 6-4, 6-3 after 2hr 31min on a cool evening at Rod Laver Arena.
Nadal, who caught a virus this month and sweated buckets in Saturday night`s encounter with Australian teen Bernard Tomic, said he was now feeling "perfect" just three matches away from a non-calendar year Grand Slam.
"I didn`t sweat as much tonight," he smiled. "Two days ago I was sweating like crazy and I felt tired, but today is the first day that I felt perfect physically."
With the win, Nadal moves to 25 consecutive Grand Slam match victories, equalling runs by Jimmy Connors and Pete Sampras in the 1970s and 1990s. Only Rod Laver (29) and Roger Federer (27, twice) have longer streaks.
Nadal will meet David Ferrer on Wednesday in the Australian Open`s first all-Spanish quarter-final in 14 years. The French Open, Wimbledon and US Open champion can become the first man to hold all four major titles since 1969.
Earlier Murray barely gave Austria`s Jurgen Melzer a look in his 6-3, 6-1, 6-1 win which maintained British hopes of ending a men`s Slam drought dating back to Fred Perry`s 1936 US Open victory.
The world number five, beaten by Federer in last year`s final, said he was surprised by the easy win over the 11th seed which, like Nadal, puts him into the last eight without dropping a set.
"I`ve played Jurgen in the Slams a few times, including here two years ago, and I was expecting a tough match and I was surprised by beating him in three sets," Murray said.
"I hit the ball well from the start of the match and I played some of my best tennis (here) last year. I don`t want to get carried away as I haven`t won this kind of thing
