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. Of those 11 matches, all bar one has been played on a hard court, with the sole exception coming on the grass at Queen's in 2008 where Isner won 7-6 6-4.
John Isner and Kevin Anderson were level at 20-20 with the match, which has crossed six hours, the second-longest singles contest ever at the All England Club.
"I hope this is a sign for Grand Slams to change".
Isner had previously come out victorious in the longest match in history in 2010 at Wimbledon against Nicolas Mahut, which lasted 11 hours and five minutes over three days.
Until Friday, he had not dropped serve until Anderson halted that run at 110 service games in the third set. In most cases, this is still a compelling finish, but when you put two heavy-hitting goliaths against each other, what results is a six-hour slog that can cause delays across the tournament.
Anderson will now have to recover quickly in order to overcome a giant of a different kind in the men's finals on Sunday: either the top-seeded Rafael Nadal of Spain, a two-time victor at Wimbledon, or three-time champion Djokovic, who posted a picture on social media of himself playing marbles.
Krejcikova and Siniakova missed two chances to serve out the first set from 5-2 up, but regained their composure to break once more at 5-5 and served out at the third attempt.
That point ended up actually setting up the winning break for Anderson.
But not only did Anderson jump back to his feet, the South African astonishingly switched his racket into his left hand and, gripping it half way up the handle, hit a forehand to get the ball back and take the point before he broke and then went on to win the match.
Many would argue Anderson and Isner deserve similar recognition after the friends warmly embraced at the net before receiving a standing ovation from tennis's most famous centre-court crowd.
Reflecting on the gruelling game, Anderson called on grand slam authorities to consider changing the format of matches. Isner wasted a set point in the opener.
"I think it's long overdue", Isner said.
"I don't know what to say right now".
