LONDON, ENGLAND - JULY 14: Novak Djokovic of Serbia shakes hands with Rafael Nadal of Spain (R) after their Men's Singles semi-final match on day twelve of the Wimbledon Lawn Tennis Championships at All England Lawn Tennis and Croquet Club on July 14, 2018 in London, England.
Djokovic's thriller against long-time rival Rafael Nadal lasted a mere five hours 15 minutes, but only three sets of that could be completed before the Wimbledon curfew at 11 pm on Friday, and the pair had to come back on Saturday to finish off before the women's final.

The world was a demonstrably different place when Kevin Anderson and John Isner first took the court Friday for what would become a marathon Wimbledon semifinal.
The right-handed Anderson slipped and fell, but scrambled back to his feet in time to hit a return left-handed and continue the point before Isner eventually pushed a forehand just wide.
On Sunday, he plays Nadal or Novak Djokovic, who have a combined 29 major titles.
Djokovic, the Wimbledon champion in 2011, 2014 and 2015, will be bidding for a 13th Grand Slam title when he faces Anderson on Sunday.
I won some great matches, especially in the quarter-finals against Del Potro. "I can feel the crowd (get) pretty antsy for us to get off the court".
It was the kind of ingeniousness that was needed to break the serve-hold-serve-hold deadlock that went on for nearly three hours in the deciding set alone as Anderson became the first South African man in 97 years to reach the Wimbledon final.More news: Hard to see Serena losing to Kerber: Boris Becker

"I really hope we can look at it and address this, because at the end, you don't even feel that great out there".
Almost three punishing hours later they both left Centre Court with their title hopes still intact. "When playing for 3, 4, 5 hours straight, you need the right fuel... and for me, the right fuel is plant-based".
The 12-time grand slam victor will compete against South African eighth seed Anderson, who plays in his second major final, at 2 pm (1200 GMT) on Sunday.
Having the roof shut meant every sound was amplified as it ricocheted off the dome - the thwack of ball off racket, the players' grunts, the spectators' applause.
Isner, who has now competed in the two longest matches in Wimbledon history, also called for change. Still, Isner did jokingly ask chair umpire Marija Cicak at one point during the last set whether they could play a tiebreaker.
Nadal missed 5 break points in the decider and had to pay the price at last as 12-time Grand Slam champion Djokovic reached the major's final.
"If the previous part of the match started with the roof on, there was logic but I don't understand why it had to be closed".
Djokovic gives Nadal a challenge no other player can.
Following his defeat Friday, Isner said the time was "overdue" to institute fifth-set tiebreaks - for the good of players, fans and broadcasters alike.
