Defending champion Novak Djokovic of Serbia overcame a scare to notch up a record 80th Wimbledon win on Monday with a hardfought four-sets victory over Kwon Soon-woo of South Korea.

Six-time champion Djokovic triumphed 6-3, 3-6, 6-3, 6-4 under the Centre Court roof. However, the top seed was made to work hard after falling a break down in the opening two sets against his 81st-ranked opponent—losing the second of those.
