Tennis fans knew the Wimbledon semi-final between Kevin Anderson and John Isner might not be a short encounter, but surely they didn't expect it to last this long.
The pair broke the record for SW19's longest ever semi-final match during the fifth set, surpassing the 2013 clash between Novak Djokovic and Juan Martin Del Potro, which lasted four hours and 43 minutes.
At the time of writing, the match had gone past the six-hour mark, with Isner and world number eight Anderson locked at 20-20 in the final set after trading service games for hours.
Three-time Wimbledon winner Djokovic has been waiting all day to step on to Centre Court for the other semi-final against Rafael Nadal, the match where the majority of fans would have solely got tickets for - they might not get to see that match now.
Isner has history for playing long matches at Wimbledon, having endured a 70-68 fifth-set tiebreak against Nicolas Mahut in 2010, a match which spanned three days.
Pre-match, many underplayed Anderson and Isner's all-round on-court talents, thinking that it would be a long slog between two 'serve-bots'.
And they were somewhat right, with numerous aces from both athletes, but at 10-10 in the final set tiebreaker, American giant Isner had the advantage, and what he did next was a thing of beauty.
Anderson had almost surely forced the game back to deuce with a close-range dink over the net, but a tired Isner somehow stormed across the court to slam home a passing winner.
It wasn't so much the shot that the fans particularly loved though, it was Isner's actions following the winner.
As he watched the ball travel past his opponent to go 11-10 up, Isner's movements found him by the side of his chair, and he nonchalantly sat down like nothing ever happened.
Despite his sometimes perceived arrogance during matches, fans couldn't help but react positively to what Isner did.
