American 12th seed Taylor Fritz dumped last year’s Australian Open runner-up Stefanos Tsitsipas out of the tournament on Sunday to set up a quarter-final with defending champion Novak Djokovic. 

There was little to separate them in the opening two sets but Fritz stepped up a gear to beat the Greek seventh seed 7-6 (7/3), 5-7, 6-3, 6-3 in a shade over three hours. He said the key was “just trusting my shots” and that he had served well throughout.
