Djokovic raced out to a strong opening set, but Nadal found his bearings and his forehand in the second.
Novak Djokovic in action against Rafael Nadal in the Wimbledon semifinal on 14 July 2018.
The eighth seed will face either twice champion Rafael Nadal or three-times victor Novak Djokovic in Sunday's final.
Anderson, 32, will vie for the title on Sunday against the victor of the match between Nadal, the world No. 1, and three-time champion Novak Djokovic.
The clash will go down in history as the second longest semi-final match in Wimbledon's history behind Kevin Anderson and John Isner's thrilling six hour, 36 minute meeting earlier in the week. Just playing like that in those conditions was really tough on both of us.
Along the way, they have fought out a series of classic and epic battles including Djokovic's 5-7, 6-4, 6-2, 6-7 (5/7), 7-5 Australian Open final victory in 2012.
10 killed in second attack on Election Rally
About 131 people were killed and more than 150 injured in Friday's Mastung blast, a health official told Arab News on Saturday. A Pakistani mourns over a dead body of his family member who is killed in a bomb attack, at a mortuary in Quetta, Pakistan .
Of the task against Anderson, Djokovic said: "Hopefully we can first of all play, both of us get out on court".
Nadal had three set points in the third set tiebreaker - one of them created off a lung-busting 23-shot rally. Between that and the energy-sapper against Isner, it's hard to imagine how Anderson will have much left for Sunday's final, his second at a major.
He'll face Kevin Anderson in Sunday's final.
"If I have to compare the game that I've played, the level of tennis that I've had (all of) those years and today, I think it's pretty close".
Nadal will regret his missed opportunity the night before, when he was in the ascendancy but passed up two set points.
Anderson, a 32-year-old from South Africa, eliminated eight-time Wimbledon champion Roger Federer in a 13-11 fifth set in the quarterfinals Wednesday. They combined for 102 aces - 53 by Isner, 49 by Anderson.
Rafael Nadal is slightly favorite against Novak Djokovic, says coach
A set littered with one lengthy rally after another, eventually went to Nadal on serve, finally giving him the match. Del Potro made him pay as he pounced on his first chance to raise the prospect of another upset on day nine.
While Nadal hasn't really been off the scene at all, Djokovic is ending a string of five straight majors in which he didn't play a semifinal match - his longest such stretch since 2006.
"It's been a roller-coaster ride for him the last couple rounds, but he had a day off, which means a lot", Djokovic said. "It is what it is, I'm in the final of Wimbledon and it's an incredible achievement for me". For all the talk of the Federer/Nadal rivalry, the Djokovic/Nadal pairing may have produced the most fiery tennis ever. Marin Cilic beat Sam Querrey in that 2012 third-round match.
Isner, who previously said Wimbledon had become "a house of horrors" for him since his 2010 match, had been trying to become the first American man to reach the final since Andy Roddick in 2009.
For his part, Djokovic is eyeing a 13th major after making the semi-finals of a Slam for the first time since finishing runner-up at the 2016 US Open. I gave it my best, and that's it.
Friday proved to be another long day for Anderson, who said after the match that he hoped the 50-game fifth set would be "a sign for Grand Slams to change".
Could we be about to see the sixth and last break of a match that would end up with 90 holds?
