Novak Djokovic has overcame an uncharacteristically unsteady start to avoid what would have been his earliest exit at Wimbledon since 2016.

Novak Djokovic may never quite know how he came through on Centre Court against Alex De Minaur, but the beauty of Grand Slam tennis is that he doesn’t need to know. His mind switches immediately to the Wimbledon quarter-finals, which he has reached for the 16th time.

Things looked shaky early, but Novak Djokovic eventually found his form in a fourth round win over Alex de Minaur at Wimbledon on Monday. After dropping the first game 6-1, Djokovic rallied to win the next three sets 6-4, 6-4, 6-4 to advance to the quarterfinals.
