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.
Meanwhile, 14th seed Sofia Kenin has brought the curtain down on Coco Gauff's Australian Open coming-out party, winning through to a maiden Grand Slam quarter-final.
In an all-American fourth-round affair, Kenin kept her cool to come back from a set down and score a 6-7 (5-7) 6-3 6-0 victory on Sunday over the teen sensation.
Kenin, 21, has never been past the fourth round at a major and she'll have a golden chance to reach semi-finals at Melbourne Park, facing Serena Williams' slayer Qiang Wang or Tunisian surprise packet Ons Jabeur.
