Among the sport's four Grand Slams, only the U.S. Open played tiebreaks to settle the fifth set. Anderson's serve will keep him in this match when other parts of his game desert him, and this can be enough to see him take the contest to five sets. The No. 9 seed Anderson will square off against the victor of Rafael Nadal and Novak Djokovic, which was suspended after three sets, and will be continuing on Saturday.
The two semi-finals were the longest ever played at Wimbledon, and Djokovic said the physical toll was enormous.
- At 6 hours 36 minutes, Anderson's victory against John Isner in the semi-finals was the second-longest match in Grand Slam history.
Isner was bidding to become the first US man to make a Grand Slam singles final since Andy Roddick at 2009 Wimbledon, to end the nation's longest drought in his 41st career Grand Slam.
After five hours and 15 minutes - played over two days - Djokovic secured a berth in his first Major final since the runner-up finish at US Open 2016, beating Nadal 6-4, 3-6, 7-6 (9), 3-6, 10-8 to set up a clash against Kevin Anderson.
Calls for fifth-set tiebreakers only grew louder after the suspension of Nadal-Djokovic, as the match was pushed back because Isner and Anderson's match went so long as they played out the fifth set.
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 was very emotional after the match, as well, because it's been a long 15 months for me, you know, trying to overcome different obstacles".
Anderson made it clear Grand Slam tournament organisers should consider a rule change to make the deciding set of five-set matches less gruelling. However, Djokovic confirmed that he does not to eat meat for both ethical and health reasons.More news: Industrial park blast kills 19, hurts 12 in southwest China
The 11-time French Open champion reflected upon his journey in this summer's grass court event in Wimbledon, saying: "I played great. I think we're quite even", Djokovic said.
"Right now I feel awful", the 33-year-old Isner said, noting he developed a foot blister at some point in the match.
Anderson will be playing in his second Major final after losing to Nadal at Flushing Meadows a year ago. "Basically until the last shot, I didn't know if I was going to win".
The eighth-seeded Anderson became the first person to break the serve of ninth-seeded Isner, doing so once in the third set, twice in the fourth set and again during the fifth set.
Fans in stands expressed due appreciation for Isner and Anderson's effort and skill - to a point.
Saturday on Twitter, Isner not only thanked Anderson for responding to the epic with humility and empathy, but he also wished the South African player the "best of luck" in the final.
"I need to reset as much as possible", Anderson said. At Wimbledon he's shown the hunger to go a step further.
The Serb led by two sets to one when play stopped at 23:02 BST on Friday. Djokovic would have his first break-point - and match-point - when the score was 8-7, but Nadal saved that with a courageous and cheeky drop shot.
