Britain's Emma Raducanu beat Canadian Leylah Fernandez 6-4 6-3 in the battle of the teens to be crowned US Open champion.
She is the first qualifier to win a Grand Slam title and the first British woman to hoist a major trophy since Virginia Wade triumphed at Wimbledon in 1977.
Here are some reactions to the win:
In a message to Raducanu, Queen Elizabeth said, "I send my congratulations to you on your success in winning the United States Open Tennis Championships. It is a remarkable achievement at such a young age, and is testament to your hard work and dedication."
'I have no doubt your outstanding performance, and that of your opponent Leylah Fernandez, will inspire the next generation of tennis players.'

A star is born- Emma Raducanu makes history - never has a qualifier won a major- men or women- and she is just getting started. And will never have to qualify again:)

Seven-time Grand Slam winner Mats Wilander on Eurosport said, "I have never heard a crowd in Grand Slam tennis being this loud, this appreciative of the players and the player responding. This was an epic of the US Open. It was a great comeback of the US Open, it was just an amazing two weeks."
Alex Corretja, former World No.2 and Eurosport Tennis Expert said, "I don't think we will see this again from a player from qualifiers, not losing games, sets, that's something superior Emma did very well. It's such great news for tennis, women's tennis and sports in general."
British actor Stephen Fry called it a 'glorious day' for both Emma Raducanu and Canadian Leylah Fernandez in his tweet.
What a glorious day for two remarkable young women. Yes, it may be ‘only’ sport, but in that ‘only’ there can be found so much of human joy, despair, glory, disappointment, wonder and hope. A brief flicker of light in a dark world. #EmmaRaducanu #LeylahFernandez #USOpenFinal
