Novak Djokovic established himself as the clear favourite to win a 10th Australian Open title by dismantling home hope Alex De Minaur in the fourth round.
Djokovic reported no pain from his suspect hamstring after a 6-2 6-1 6-2 victory that sets up a clash with fifth seed Andrey Rublev, who defeated Holger Rune over five sets in one of the matches of the tournament.
Fifth seed Aryna Sabalenka produced a terrific display to see off Belinda Bencic while Pole Magda Linette knocked out fourth seed Caroline Garcia in the latest shock.
