Emma Raducanu "Didn't Want To Give Up On the trophy."

She is also the first qualifying woman to win a major title. "It means everything to have this trophy, and I don't want to play it right now," he told former England number one Tim Henman on Amazon Prime. "Yesterday, I had a strange feeling that I can't correctly classify - I feel like it's pretty standard. So when I came out, everything was, as usual, point by point.

"I had to fight hard for the first set and move on to the second. At key moments I came out with some clutch fixes." His sensational run at Flushing Meadows stimulated the audience's imagination, and he hopes his win will make others dream big. But I can't believe the trust I've put in and won," he said.

"I started as a little girl, but I think the biggest thing you can think of is a moment of victory, and you will celebrate with your team trying to get into the box. "It went round in my head for a few nights. Then, finally, I fell asleep to it."

"I only have freedom of movement."

Victory over Canadian Leila Fernandez meant a tremendous improvement for Raducanu, who debuted for the WTA main draw in June. He is only playing in his second Grand Slam tournament after reaching the fourth round of Wimbledon as a substitute earlier this year.

Raducanu is the youngest women's champion since Maria Sharapova won Wimbledon in 2004 and the youngest Briton to win a slam title. "It shows the future of women's tennis, and the depth of the game is great - every player who enters the draw has a chance to win every tournament," she said in an on-court interview.

"I hope the next generation will follow in the footsteps of some of the legends like Billy Jean [King] here." He recovered 5-3 from an uncomfortable fall as he served for the game, saving two breakpoints from a relentless Fernandez before scoring his third championship point.

"I kind of thought it would throw me off balance - I'm not praying for double guilt!" said Radukanu. The level is very high, and I look forward to competing against each other in more tournaments and looking forward to the final." Raducanu played ten games to win the title, including three qualifying rounds, beating Olympic gold medalists Belinda Bencic and Maria Sakari, respectively, in the quarter-finals.

"I don't feel any pressure at all. I'm 18 years old and have the freedom to whatever comes my way," he said. "That's how I see every game here in the US. But, yes, it gave me that trophy, so I don't think I have to change anything."
