Kevin Anderson became the first South African man to reach the Wimbledon final since 1921 after outlasting American John Isner 7-6 (6) 6-7 (5) 6-7 (9) 6-4 26-24 in a marathon encounter Friday.
The two players battled for six hours and 36 minutes, the longest ever singles semi-final at the All England Club, before Anderson advanced to the title clash in his 10th main draw appearance.
Eighth seed Anderson will meet either twice champion Rafael Nadal or three-time winner Novak Djokovic in Sunday's final.
"I don't know what to say. Just playing like that in those conditions was really tough on both of us. At the end you feel like it is a draw, but someone has to win," Anderson said.
"John is a great guy and I really feel for him. If I was on the opposite side I don't know how you can take that playing for so long and coming out short...getting through something like that is quite different.
"I've known John for such a long time, he is a great guy. To be honest he has pushed me through my career and had a great one himself. I have pushed myself harder because of the success he has had."
In the day's second semi-final, contested under the roof, Djokovic led Nadal 6-4 3-6 7-6 (9) before play was suspended for the day after the 2200GMT deadline was reached.
The match will resume Saturday.

Isner said he was looking forward to a few days' rest after his taxing last-four defeat by Anderson.
"I feel pretty terrible. My left heel is killing me. I have an awful blister on my right foot. I've felt better before," the American said. "A few days' rest, maybe more than that, and I'll recoup and try to get all healed up again.
"It stinks to lose, but I gave it everything I had. I just lost to someone who is just a little bit better at the end."

ANDERSON SEEKS FORMAT CHANGE AFTER EPIC WIN
Anderson said grand slam authorities had to mull changing their format following his draining semi-final encounter with Isner which lasted over six hours.
"I really hope this a sign for grand slams to change this format. For us to be out there for that amount of time, I really hope we can address this," the South African, who won the fifth set 26-24 to beat Isner, said.
"At the same time I'm through to the final. I'm definitely going to have to recover as much as I can. It'll take a long time to process what's happened [Friday] but I'm into the final and that's a dream come true."
