Defending champion Novak Djokovic was taken the distance by Gilles Simon in the Australian Open men’s singles fourth round on Sunday. The five-time champion took the first set 6-3 before surrendering the second 7-6. The Serb took the third 6-4 before Simon struck back by the same scoreline in the fourth.
The world number one grabbed the deciding set 6-3 in 41 minutes at the Rod Laver Arena. In total the pair spent four hours and 32 minutes on court. Djokovic hit 62 winners but committed an unusually high number of unforced errors – 100 in total.
The 28-year-old will meet Kei Nishikori in the quarters after the Japanese saw off Jo-Wilfried Tsonga 6-4, 6-2, 6-4. Tomas Berdych is also into the quarter-finals after a gruelling 4-6, 6-4, 6-3, 1-6, 6-3 win over Spain’s Roberto Bautista Agut at the Margaret Court Arena. The Czech will come up against Roger Federer or David Goffin next.
