Kyle Edmund produced the performance of his career at Roland Garros - and was cheered all the way by Andy Murray, who dashed from the locker room to lend his high-profile support.
Tennis is an individual sport and it's rare to see a player ranked third in the world step outside their personal bubble to cheer on a rival, unless they share a surname.
But Murray makes no secret he wants more British talent around him and Edmund's first Tour and first Grand Slam victory gives cause for optimism ahead of Great Britain's Davis Cup quarter-final with France in July.
He took just under three hours to beat French veteran Stephane Robert 2-6, 6-4, 6-3, 5-7, 6-2, firing an incredible 41 forehand winners past his rival in the process.
Heather Watson also joined Murray and Edmund in the French Open second round after a straight sets win over Mathilde Johansson, the first time in four years three British players have progressed that far in Paris.
But third seed Murray - who beat Argentinian qualifier Facundo Arguello 6-3, 6-3, 6-1 - urged perspective despite the feel good factor.
"A lot of the other nations have multiple players going deep into these tournaments and ultimately that's where you want to get to," he said.
"Tennis in the UK is obviously a big sport. There's a huge amount of money invested in it, so you want to try to get as much depth as possible in the rankings.
"For us it's great but I don't think the other countries would be saying the same thing. However, it's obviously nice - the more British players in the tournament the better."
Edmund silenced a vocal home crowd to claim victory on a day when fellow British players Jo Konta and Aljaz Bedene both took sets before bowing out against Denisa Allertova and Dominic Thiem.
His win is likely to propel him into the world's top 100 and it's the first time two British men have been in the second round at Roland Garros since Tim Henman and Murray in 2006.
Next up is Australian Nick Kyrgios, who is three months younger than 20-year old Edmund and has already reached a Grand Slam quarter-final and career high ranking of world number 30. More perspective about the challenge ahead.
And the winner of that could face Murray, now unbeaten on clay for 11 matches, who plays either Canada's Vasek Pospisil or Portugal's Joao Sousa in the second round.
"I knew I had the game to beat him but that’s one thing and doing it is another," said Edmund.
"The crowd was almost like having another player against you but I expected it and it's a great experience to beat a player in five sets in their own backyard."
