The 18-year-old has now surpassed her breakthrough run at Wimbledon where she reached the fourth round in the summer.
Here, the PA news agency takes a closer look at Raducanu.
Raducanu was actually born in Toronto in 2002 to a Chinese mother and Romanian father and the family moved over to England when she was two. Although she has lived in London, she has fond memories of going to see her grandmother in Romania. She said: “My grandma, Mamiya, still lives in central Bucharest. I go back a couple of times a year, stay with her, see her. It’s really nice. I love the food, to be honest. I mean, the food is unbelievable. And my grandma’s cooking is also something special. I do have ties to Bucharest.”
A sporting youth
It was perhaps inevitable Raducanu would have a career in professional sport, given the way her father pushed her as a youngster. She started off attending ballet classes, but her father decided sport was the way forward and had his daughter do horse riding, swimming, tap dancing, basketball, skiing, golf, go-karting and motocross, all alongside her tennis practice.
A recent debut
It is incredible to think that Raducanu only made her first WTA Tour main draw appearance at this year’s Nottingham Open. She lost 6-4 6-3 to compatriot Harriet Dart in the first round before making the quarter-finals of a lower-level tournament at the same venue the following week. That persuaded Wimbledon to offer her a wild card into the main draw and she went on to become the youngest British woman to reach the second week at SW19 in the Open era.
Success at an early age
Raducanu has some sort of form at the US Open, having made it to the 2018 juniors quarter-finals. She won the first ITF junior title she was allowed to compete in, aged just 13.
