Quarter-finals

Djokovic, Federer and Ash Barty through to quarters

Djokovic continued his imperious progress through the men's draw, negotiating a potentially tricky encounter with Diego Schwartzman 6-3 6-4 6-4 to reach the last eight at Melbourne Park for the 11th time.

The seven-times champion only added to a strong feeling around the tournament that the Serbian is again the man to beat at the year's first Grand Slam as he ousted the Argentine in just over two hours at Rod Laver Arena.

Federer, chasing a record-extending 21st Grand Slam, came from behind to beat Hungarian Marton Fucsovics 4-6 6-1 6-2 6-2.
