The 27-year-old Briton saved three set points but could do nothing about the fourth as Djokovic wrapped up the opener. Having delayed the start of the match for a few minutes while he was in the treatment room, Djokovic wasted no time in racing into a 3-0 lead before Norrie slowed down his opponent's charge with a couple of holds.
'It's not how we treat each other, but it is allowed.' 'Those are the things we players know are not fair play,' Djokovic said. He had already been irritated by the British number one's shouts of 'Come on', before being hit in the ankle when he had already given up the point.
