Defending Australian Open champion Novak Djokovic has set up a quarter-final showdown with Milos Raonic with a straight-sets win over Diego Schwartzman on Rod Laver Arena.

The No.2 seed was rarely troubled by the 14th-seeded Argentine during Sunday’s fourth-round clash and advanced 6-3 6-4 6-4.

Earlier, Raonic was the first player through to the men’s quarter-finals when he accounted for 2018 finalist Marin Cilic 6-4 6-3 7-5 on Margaret Court Arena.
