Two hours and 18 minutes later, Anderson breaks thousands of hearts, across the globe, as he defeats the top seeded player and defending champion Federer from his kingdom Wimbledon! .
Federer had a match point at 5-4 in the third set, but Kevin Anderson-the 6-foot-8 ball smasher from South Africa-saved that break point and went on to win the set.
Federer was 4-0 against Anderson entering the day, winning every set they'd ever played against each other. After fighting back from match point and love-40 on his serve to take the third set, the South African broke Federer in the seventh game of the fourth set.
When Wimbledon got underway July 2, tennis fans of all loyalties seemed united in rooting for one pairing in Sunday's men's final: a reprise of the 2008 clash between Federer and Nadal, which produced what many believe is the greatest match in tennis history.
That ended Federer's streak of consecutive sets won at the All England Club at 34, with the former world No 1 unable to break his own record.
When he finished runner-up to Rafael Nadal at the US Open past year, he was the first South African man in a Slam final since Curren at the 1984 Australian Open.
Nishikori, who had won only two matches in 15 meetings with the 12-time major victor, broke for 1-0 in the fourth but was broken straight back.

On Friday, Anderson will play another big server, John Isner of the United States, who defeated Milos Raonic, 6-7 (5-7), 7-6 (9-7), 6-4, 6-3, to reach his first Grand Slam semifinal at age 33. I scraped through the third and fourth sets.
The three-time champion spoke to Serbian media after his straight sets victory over Khachanov and revealed he has put in a request to play on Centre Court, having played there only once in this year's tournament. There's hopefully two more matches still to be played.
Novak Djokovic, Nadal's one-time archrival, has had a lot of ups and downs over the past few years, but he's back in the semifinal to face off against Nadal.
Soon enough, Djokovic was on his way to the semi-finals, where he will meet Rafael Nadal.
It would be unwise to write off his chances of adding to his 20 grand slam titles in light of his three in the past 18 months but it is not going to get any easier, certainly at Wimbledon.
"I was actually playing really high-quality tennis, having a few sniffs on his serve, nearly felt my mind wondering, Well, maybe I can do this".
'I'm pleased I'll be staying there right now'.
