Novak Djokovic battled to a 17th consecutive victory over Kei Nishikori to keep his bid for the calendar Grand Slam on track.

Not since a semi-final win over the Serbian in New York in 2014 had Nishikori got the better of Djokovic, and he won just two games at the Olympics in Tokyo earlier this summer.
