Novak Djokovic overcame a challenging start to defeat unseeded Australian Alexei Popyrin 4-6, 6-3, 6-4, 7-6(3) and advance to the fourth round of Wimbledon on Saturday.
Despite Popyrin's strong performance in the first set, which he sealed with a second-serve ace, seven-time Wimbledon champion Djokovic quickly regained his form and took control of the match.
