Novak Djokovic has advanced to the Wimbledon round of 16 after overcoming Australia's Alexei Popyrin in a challenging four-set match, showcasing strong mental resolve and impressive tiebreak performance. Despite dropping the first set, Djokovic's experience and skill carried him through to a 4-6, 6-3, 6-4, 7-6 victory. His recent knee surgery has not hindered his performance significantly, although he acknowledges not being at his peak movement yet and hopes to improve as the tournament progresses. Djokovic will next face Denmark's Holger Rune, who mounted a significant comeback in his previous match. The tournament has also seen some surprising outcomes, including Hubert Hurkacz's retirement due to injury and Jessica Pegula's unexpected defeat. Djokovic's journey continues as he aims for an eighth Wimbledon title amidst rigorous competition.
