MELBOURNE (Reuters) - Jannik Sinner was far from his best but found a way to come out on top in the key moments as he reached the quarter-finals of the Australian Open with a 6-4 7-5 6-3 win over Karen Khachanov on Sunday.

The Italian fourth seed, widely tipped as a title contender after a scorching finish to last season, had stormed into the fourth round without really being tested but knew he had been in a match on a blustery Margaret Court Arena.
