Novak Djokovic steamrolled local hope Alex De Minaur 6-2, 6-1, 6-2 to ease into the quarter-finals of the Australian open with a statement win in his quest for a 10th title at the grand slam.

Djokovic drew first blood after a breathless start to the match when de Minaur crashed a forehand into the net to allow the fourth seed to go up 4-2 and the Serbian consolidated the break and struck again to claim the first set.

Having never lost at Melbourne Park since the fourth round in 2018, the 35-year-old was in no mood to give de Minaur a chance, as he raced out of the blocks and dominated his opponent with blistering shots on both wings.

Up two sets to love and with his heavily-strapped hamstring cooperating after scares in the last two rounds, Djokovic moved in for the kill by taking the first four games of the third and finished in style to gear up for fifth seed Andrey Rublev next.

Unseeded Tommy Paul ensured three American men will contest the quarter-finals for the first time since 2000 after he beat 24th seeded Spaniard Roberto Bautista.
