Serb battles to win over Botic van de Zandschulp

Djokovic: ‘I’m too stressed on the court very often’

Novak Djokovic chalked up his 400th grand slam victory with a 6-3, 6-4, 7-6(4) defeat of Botic van de Zandschulp to reach the fourth round, but the Serbian player was fortunate not to receive a code violation after losing his cool.

Djokovic opened the evening session on a steamy day in which play continued under the main show court roofs and eased to a 5-3 lead before firing a sublime backhand crosscourt winner and celebrating with his arms out to mimic an airplane.

He endured minor turbulence following that point but had no trouble taking full flight again as he broke in the opening game of the second set when a deflated Van de Zandschulp fired his backhand long.
