Defending champion Novak Djokovic stayed on track for an eighth Australian Open title with a 6-3, 6-4, 6-4 win over Diego Schwartzman in the fourth round.
It's the 11th time that Djokovic has reached the quarterfinals at Melbourne Park.
He improved his career record to 4-0 over Schwartzman, including previous wins at the 2014 U.S. Open and the 2017 French Open.
Djokovic will next play 2016 Wimbledon finalist Milos Raonic, who advanced over Marin Cilic in straight sets. Djokovic has a 9-0 career record over the big-serving Canadian, including a win in the quarterfinals at Melbourne Park in 2015.
''Quite different match up to the one today,'' Djokovic said of the quarterfinal encounter. ''I've got to be ready for missiles coming from the other side of the net.''
