Raducanu had three qualifying rounds to be eligible for the main draw.
US Open 2021 Venue Flushing Meadows New York Date: 30-08-12 September Coverage. Daily radio commentary on BBC Radio 5 Live Sports Extra/BBC Sport website. Also, match reports and text commentary on selected matches.
Emma Raducanu, a British teenager, put on another incredible performance to reach the quarter-finals of the US Open as she made her dream New York debut.
The 18-year old qualifier won 11 games in succession in a 6-2, 6-1 victory over Shelby Rogers.
Raducanu won the most important match of her career on the largest tennis court in the country, winning a tiebreak in the first game and dominating in style.
For a place in semi-finals, she will be facing Olympic champion Belinda Bencic.
After Shelby's fourth match point, the Briton fell to her knees at Arthur Ashe Stadium.
Raducanu captured the imagination of the British public with his run to Wimbledon's fourth round as a wildcard. In July, he has gone one better. A series of impressive displays have led pundits to predict big things for the world number 150.
It feels incredible. "It feels absolutely amazing. Shelby is a great opponent. She's done so well at the US Open.
"But I'm so glad to have made it through and have been able to overcome some nerves at the start."
Raducanu shakes off nerves at the big stage
Raducanu arrived at court smiling big, waving to the crowd, and looking relaxed. But, early nerves set in on a court that can hold 24,000 people, where the greats of the game, including American Billie Jean King, and Britain's Virginia Wade, were watching.
After being broken in the first game, she was at risk of losing 3-0. She then fought for a hold in her second service match. This saved two break points.
This held seemed to calm her nerves, and she quickly moved up the gears in order to win the match against world number 43 Ashleigh Barty.
Rogers won the second set with a consolation game, but it was Raducanu who came out on top in the final.
Wade, a British woman who won a Grand Slam singles title in 1977, was Wade. Raducanu said to Wade: "Thanks so much for watching me play. It was a great honor to have you here. I'll do my best, and we'll see what happens."
Raducanu's maths add up
Raducanu's Wimbledon run was over before she could retire against Ajla Tomljanovic from Australia in her 16th match. She was experiencing dizziness and difficulty breathing.
She said that she was "caught up" in the Wimbledon experience.
She reached her maiden WTA Final just weeks later and also received her A Level results: an A* in maths, and an A economics.
Shelby was the only one she had to beat. She made just 14 errors unforced compared to Shelby's 29. Shelby also scored 18 wins in a 66-minute match.
Raducanu, who was 338th in the world before she arrived at Wimbledon, will make it into the top 100 when the next rankings are released after the US Open.
This would allow her to automatically enter Grand Slams, and depending on how far she gets in New York, she might even surpass Johanna Konta for British number one.
"It's impossible to not get excited" - reaction
Miles Maclagan (former British Davis Cup player): Miles Maclagan on BBC Radio 5 Live Sports Extra: “There is something special to Raducanu's way of taking it all in. Andy Murray was 16 when I first met him at Roland Garros. He wasn't overwhelmed by the experience, and she keeps reminding me of that. Is there a limit? We don't know the limit yet."
David Law, BBC Radio 5 Live Sports Extra commentator: "It is impossible to not be excited. I don't want to get too excited over a young player, for fear of pulling her into a final before she has even reached the semis. But what it feels like to watch this is what it was like to see Iga Swiatek win the French Open [in 2020].
Raducanu won a Grand Slam's worth tennis matches with four qualifying matches and one match, and has not dropped a set. Raducanu will face Bencic in a tough match, but Raducanu makes it look easy."
Naomi Broady, British player, BBC Radio 5 Live Sports Extra: I spoke to Emma before Wimbledon and was struck by her foresight, belief, and ability to get through.
"She has that self-belief even before she's entered her first Grand Slam. That's why I don't find it surprising or surprising that she got to this point. It is right to feel excited, not only about the future but also about what she does right now. Raducanu's calm and positive attitude in these situations are beyond her years.
