Seven-time champion Novak Djokovic will contest his 11th Australian Open quarterfinal following a commanding victory over dogged Argentine Diego Schwartzman on Sunday.
The second seed had the 14th seed scurrying to the far reaches of the court at Rod Laver Arena in a 6-3 6-4 6-4 victory.
Despite having prevailed on all three occasions the pair had met, Djokovic was well prepared for the danger that zipped about the baseline across from him.
“It feels great. I had a fantastic couple of matches in a row, center court, last two rounds,” Djokovic said.
“I felt more confident going through the ball, hitting serves really well.
“Today was a good test because Diego was in form, he hasn't dropped a set in three rounds. Obviously he can be a very dangerous opponent from the baseline if you give him time. I knew that.
“I stepped out on the court with a clear game plan what I need to do. I think I kept things pretty much in control in all three sets.
“Maybe could have finished the match a bit earlier. But, you know, all in all, it was a very solid performance.”
