Novak Djokovic to face Milos Raonic in Australian Open quarter-finals

Defending champion Novak Djokovic continued his progress towards an eighth Australian Open title with a straight-sets victory against Diego Schwartzman in the fourth round.

The world No 2 defeated the Argentine 14th seed 6-3 6-4 6-4 to reach the last eight at Melbourne Park for the 11th time.

Djokovic, who extended his career record to 4-0 against Schwartzman, struck 38 winners and lost his serve just once as he clinched victory after two hours and six minutes on Rod Laver Arena.

After one break proved enough for Djokovic to win the first set, he opened up a 3-0 lead in the second set only for Schwartzman to break the top seed for the only time, ending a streak of consecutive service holds for the Serb in this event at 35.
