An exhausted Andy Murray broke down in tears after coming through his marathon last-16 clash at the Citi Open, only finishing at an astonishing time of 3am.
Afterwards, Murray slammed the playing schedule at the event. The match against Romania's Marius Copil did not start until shortly before midnight in Washington and took three hours and two minutes, resulting in the latest ever finish for a match at the event.
It is the first time the 31-year-old Murray has passed the three-hour mark in a clash since his return from a hip problem which kept him out of action for nearly a year.
The Scot came back from a set down to win 7-6(5), 3-6, 7-6(4), but a mixture of fatigue and relief saw him sobbing into his towel moments after putting the match to bed.
But he was clearly angry at the prospect of having to play again later on Thursday after his gruelling last-16 tie, and made his feelings clear.
'Finishing matches at three in the morning is not good,' he said. 'It's not good for the players, not good, I don't think, for anyone involved in the event. Not good for fans, not good for TV, nobody.
'I don't think it's reasonable [to have to play again later in the day]... and I'm disappointed in that.
'I know that the weather's tricky—I know it is—for the scheduling. But it's a very difficult position to be in when you're coming back from such a long layoff.'
