Melbourne: Novak Djokovic will contest his 23rd consecutive grand slam quarter-final after easing past Luxembourg journeyman Gilles Muller 6-4 7-5 7-5 at the Australian Open on Monday.
Djokovic was pushed by the 42nd-ranked Muller, a big-serving left-hander with the shots to rally with the top seed, but the four-times champion was almost bullet-proof on serve and cut the 31-year-old down repeatedly when he rushed to the net.
It wasn`t until the sixth game of the third set that Muller had a chance on the Serb`s serve but the former junior world number one could not take it despite four break points.
Djokovic struck a string of sumptuous winners to break Muller in the 11th game of the third set and served out the final game to love to book a quarter-final clash with Canadian eighth seed Milos Raonic.
