MELBOURNE, Australia (AP) Rafael Nadal beat Marin Cilic 6-2, 6-4, 6-3 at the Australian Open on Monday to maintain his chance of owning all four Grand Slam trophies at once, a feat that hasn't been achieved since Rod Laver won four majors in 1969.

Playing on Melbourne Park's center court named for the Australian star, Nadal advanced to a quarterfinal against Spain's David Ferrer as he attempts to add to the Grand Slam titles he won last year at the French Open, Wimbledon and the U.S. Open.

Nadal hasn't dropped a set through four rounds at Melbourne Park, despite carrying the effects of a virus he picked up two weeks ago in Qatar.
