London: Three-time major winner Stan Wawrinka was knocked out of Wimbledon yesterday, falling in five sets to 6ft 11in (2.1m) Reilly Opelka as defending champion Novak Djokovic waited to push his bid for a fifth title.

Two-time quarter-finalist Wawrinka, 34, was beaten 7-5, 3-6, 4-6, 6-4, 8-6 by his American opponent, the tallest man in the sport and 13 years his junior. Opelka fired 23 aces and 59 winners and goes on to face either 2016 runner-up Milos Raonic of Canada or Robin Haase of the Netherlands.
