Novak Djokovic reached the Wimbledon quarter-finals by completing victory over Poland’s Hubert Hurkacz when the pair returned to finish on Monday.
Djokovic was leading by two sets when they were forced off court on Sunday night because of the 11pm curfew.
The Serb, going for a record-equalling eighth men’s title, dropped the third but won 7-6 (8-6) 7-6 (8-6) 4-6 6-4.
Third seed Daniil Medvedev reached the last eight for the first time as Czech opponent Jiri Lehecka retired.
Medvedev will face Greek fifth seed Stefanos Tsitsipas – a player with who he has developed a spicy rivalry – or unseeded American Christopher Eubanks in the last eight.
Djokovic, 36, has been unbeatable at the All England Club in recent years, winning the men’s title at the past four Championships and not losing a completed match here since retiring injured in 2016.
The 23-time Grand Slam champion’s progress this year had been smooth until facing Hurkacz, not dropping a set in his opening three matches.
“I don’t recall the last time I felt this miserable in returning games thanks to Hubert’s powerful and accurate serves,” said Djokovic, who has not been beaten on Centre Court since the 2013 final against Andy Murray.
“It is one of the best serves in the word and is hard to read.
“It was not really an enjoyable match for me, this match could have gone either way.”
