Can't connect right now! Djokovic won the match 6-4, 3-6, 7-6, 3-6, 10-8. It was back in 2010, and he came out on the winning side against Nicolas Mahut in 11 hours 5 minutes, across a span of three days.
First Kevin Anderson and John Isner played out the longest match ever seen on Centre Court - the athleticism to continue throwing down serving bombs for six-and-a-half hours an achievement in itself. "In the end someone has to win", Anderson said, "I feel for John, I don't know what I might have felt at the end of such a long match, to not win".
"I feel pretty bad". If you fancy lumping on something at a short price, then go for it, but I'll be looking elsewhere.
This semifinal featured a high level of emotion from both athletes right off the bat. In the six-plus hour match, he served 53 aces and hit 129 winners. "Match point, I saw him coming in, I played a relatively solid shot", Djokovic said.
Victory for Djokovic would elevate the 31-year-old above Australian Roy Emerson into fourth place on men's tennis's all-time grand slam title leaderboard behind only Federer (20), Nadal (17) and Pete Sampras (14).
By 7-6 in the fifth, both players had won exactly 175 points for the match.
That service hold - helped by a 129 miles per hour (207.6km/h) second serve - took the American to 100 service games unbroken at this Wimbledon.
Wimbledon have to introduce tiebreaks in the fifth set because this is just ridiculous.
The 33-year-old American´s composure wasn´t helped by a delay caused by a ball boy slipping and falling. The matches that came down to tiebreaks would be nail-biting.
Now he's going to have to use Saturday to try to rest and recover so he can give it his best shot in Sunday's final. Each man also took a turn shouting toward the crowd after capturing a set, and Isner waved a hand toward the crowd during the third-set tiebreaker to generate more cheering.
The match continued its fiery back-and-forth with Nadal escaping match point 16 games into the final set, bringing spectators to their feet.
A stunning tie-break was a fitting conclusion to the day's play. "It's hard to come back after injuries for a long time and have these kind of results, so I am proud of myself".
Djokovic has endured a lot of setbacks in the past year.
Of the two men's semi-finals, Djokovic and Nadal's 52nd meeting was the proverbial 'final before the final.' And it was as close as it gets.
He is chasing an 18th Grand Slam title which would put him just two behind Federer. There was his run to the final of the US Open last year, of course, but even on grass, where his form has been below his own best, he has previously made the final at Queen's in 2015, and took Djokovic to five sets here in the same year.
