In front of the watching Andy Murray, Kyle Edmund came of age as he moved into the second round of the French Open with his first victory at a grand slam.
No other British male besides Murray has won a match at Roland Garros since Tim Henman in 2006, so it was fitting that the Scot was there on No.7 Court to cheer on 20-year-old Edmund.
The world No.121 had never gone to five sets, and was forced to battle through cramp, but he proved his mettle by seeing off Frenchman Stephane Robert, an opponent 15 years his senior and 429 places below him in the world rankings.
Edmund won 2-6 6-4 6-3 5-7 6-2 in just under three hours, finishing at 9.20pm local time, after Murray had dispatched Argentina's Facundo Arguello in straight sets earlier on Monday.
"He's obviously just played his match, and he's gone through all his recovery stuff and he doesn't have to come out and watch me, but he has," said Edmund.
"It just shows that he really cares. I'm just very fortunate someone like that is keen to help me. I will take as much help as I can get from him."
Well done @kyle8edmund on winning first grand slam match and likely breaking top 100 for first time ��������

Edmund next faces Australian Nick Kyrgios, with a potential third-round clash against Murray in the offing.
"I walked off the court at two sets all and said to myself this is why you get up in the morning, this is why you train and do all the hard work," Edmund said.
"I just thought, don't have any regrets. Give it everything you've got on the court. It was important I got a good start in the fifth and towards the end I started cramping. That last game, I was very relieved to get through.
"I'm obviously very pleased. It's one thing to know you have the game to win, it's another doing it. I've won one ATP match in the past, so to win my first grand-slam match with my first five-setter is special."
Heather Watson, the British women's No.1, also progressed to the third round after beating Mathilde Johansson in straight sets.
Elsewhere, Aljaz Bedene's first grand slam as a British player ended in disappointment as he was dumped out of the French Open by Austria's Dominic Thiem.
Born and raised in Slovenia, Bedene was granted UK citizenship in March after seven years spent training in Welwyn Garden City.
While the 25-year-old hopes to be allowed to represent Great Britain in their Davis Cup quarter-final against France in July, his trip to the French capital was spoilt by a 6-3 6-4 6-7(8) 6-3 loss to world No.31 Thiem.
Ranked 75 in the world, and 38th on rankings points this year, Bedene would be a useful addition to Great Britain's Davis Cup set-up, but he is yet to reach the second round at a grand slam.
