Wimbledon doesn't use tiebreakers in the fifth set for men, or third set for women, so there's nothing to prevent a match from going on and on and on - and that's precisely what Isner and Anderson did, often thanks to one ho-hum hold after another.
Anderson suggested in the aftermath that change was needed at the Grand Slams to stop players from being forced to keep playing for so long. Even Anderson said he could feel during his match that the crowd would rather be watching the next one.
Kevin Anderson didn't say much, but at the same time, he said a lot.
Djokovic came close to beating Nadal for the first time on clay, only to see the Spaniard save three match points before winning one of the greatest and - at four hours and two minutes - longest three-set matches in history.
Anderson had nearly surely forced the game back to deuce with a close-range dink over the net, but a exhausted Isner somehow stormed across the court to slam home a passing victor.More news: Croatia not just about Modric | FIFA World Cup | Croatia | France | Modric
Anderson, who had dethroned eight-time champion Roger Federer in the quarterfinals in a five-set thriller, advanced to his second grand slam finals.
A 6 hour and 35-minute battle for Greensboro native John Isner ended in defeat Friday at Wimbledon.
Djokovic missed a return as the clock ticked to 11pm but on the final lung-busting rally it was Nadal who faltered.

Djokovic-Nadal had clearly been the headline act of the day - they have five Wimbledon titles between them and met in the 2011 final while Anderson and Isner had never made the semifinals before - and their tennis was at another level from the earlier match. However, Melichar and Peschke won the next two games to seal it.
Both players had set points on their own serve, and both were denied until Anderson scooped a forehand wide and Isner was ahead. Isner has won all 95 of his service games so far.
After taking a medical timeout after the third set, Anderson surprisingly broke Isner's serve at 2-all in the fourth. This is Isner's first-ever Grand Slam tournament semifinal in his 41st appearance.
But there were, in fact, several breaks of serve. Isner, the ninth seed, sealed the tie by sending a backhand victor down the line.More news: HBO's 'Game of Thrones' leads nominations for television's Emmy awards
