Medal table | Olympic schedule | Olympic news
Novak Djokovic is one step closer to claiming an Olympic gold medal, the one piece of hardware that has eluded him throughout his career. The Serbian defeated Germany's Dominik Koepfer 7-5, 6-3 on Wednesday to move on to the quarterfinals.
His next opponent will be Greece's Stefanos Tsitsipas, and there's a little history between the two of them. They've played each other 13 times over the past six years, with Djokovic winning their last 10 matches for 11 wins overall to Tsitsipas' two.
