Novak Djokovic came through a testing Wimbledon workout to stay on course for a record-equalling eighth men's title on Thursday as Andy Murray prepared to launch his emotional farewell. Jessica Pegula became the highest-ranked player to exit the tournament so far, dumped out by China's Wang Xinyu in the second round but women's top seed Iga Swiatek cruised through. Seven-time champion Djokovic did not have it all his own way against British wild card Jacob Fearnley but came through 6-3, 6-4, 5-7, 7-5 in a match lasting three hours. It appeared to be business as usual for the Serbian as he coasted into a two-set lead on Centre Court but the 277th-ranked Fearnley broke his illustrious opponent twice in the third set to reduce the deficit.
