Third set: Novak Djokovic 6-3 6-7 (3-7) 3-1 Frances Tiafoe* (* denotes server) Djokovic unleashes a backhand described by commentators as appropriately aggressive". It wins him point one. But not point two, courtesy of another mistake. Tiafoe makes two errors. Who can handle the heat? Both are simultaneously not giving an inch but also giving an inch. Tiafoe is somewhat on the back foot at the minute. but he rescues a break point and at 30-40 races in to drive the ball deep to one corner, from where Djokovic wallops it into the net. He toiled, and Tiafoe finally has a game.
