Emma Raducanu has vowed to keep her free-swinging and carefree approach to tennis after pulling off one of the great sporting feats with victory at the US Open – just the British 18-year-old’s second ever major tournament, in which she won 10 matches after coming through qualifying, all of them in straight sets. Raducanu’s 6-4, 6-3 victory over fellow teenager Leylah Fernandez in the final made her the first British woman since Virginia Wade, who was watching from the stands, to win a slam singles title in 44 years. Raducanu said: “I’ve always dreamed of winning a grand slam. You say, ‘I want to win a grand slam’, but to have the belief I did, and actually executing, winning a grand slam, I can’t believe it. I first started when I was a little girl but I think the biggest thing that you have visions of, for me it was just winning, the winning moment, and going to celebrate with your team in the box. That’s been playing in my head a couple of nights. I’ve fallen asleep to that.” Raducanu is yet to win a match on the WTA Tour and little over three months ago she was completing her A-levels, with competitive tennis having taken a back seat for more than a year. But the teenager’s extraordinary talent was evident from an early age and she showed in her run to the fourth round of Wimbledon this summer that a big future lay ahead. Raducanu has been inundated with congratulatory messages, including from the Queen, but she said: “I still haven’t checked my phone. I have absolutely no idea what’s going on outside of the little world that we’re in here. We’ve just been in the quiet room, just enjoying the moment, taking it all in. I think today we just really need to shut out from everything, just enjoy it as a team, because it was a team effort. “I have no idea when I’m going home. I have no idea what I’m doing tomorrow. I definitely think it’s the time to just switch off from any future thoughts or any plans, any schedule. I’ve got absolutely no clue. Right now, no care in the world, I’m just loving life.” Raducanu’s team includes her parents, Ian and Renee, who were forced to watch their daughter on TV because of the continuing difficulties of international travel. One of Raducanu’s proudest achievements was impressing her dad, who has been the driving force behind the scenes. “I would have loved them to be here, and we can all celebrate together where they could be with me and experience the same things,” Raducanu continued. “But they’re watching from home very proud. My dad, he said to me, ‘You’re even better than your dad thought’, so that was reassurance. Tinie Tempah reference there. My dad is definitely very tough to please. But I managed to today.” Much was made of Raducanu’s unfortunate retirement at Wimbledon with breathing difficulties but the teenager quickly put it behind her and used it as a springboard to this incredible feat. She worked hard on being physically strong enough to compete at the top level and, through a series of matches first at lower-tier events and then at Flushing Meadows, made leaps forward with each one. She said: “At the beginning of the grass courts, I was coming fresh off my exams. I had three weeks to practise before my first tournament. I just built up every single match, every single win. I thought Wimbledon was such an incredible experience. Fourth round, second week, I couldn’t believe it. I thought, ‘What a great achievement’. “But I was still hungry. I was working hard after the grass. I didn’t have much time off. With each match and tournament, I think I’ve really built in terms of confidence, in terms of my game, in terms of my ball striking. Everything came together today. I think to pull off some of the shots I did in the big moments when I really needed it was just an accumulation of everything I’ve learnt in the past five weeks.” This was the first all-teenage final this millennium, with Canadian Fernandez having pulled off a giant-killing run including victories over two former champions in Naomi Osaka and Angelique Kerber as well as top-five seeds Elina Svitolina and Aryna Sabalenka. The 19-year-old looked the more nervous of the two initially and Raducanu surged into a 6-4, 5-2 lead. Fernandez saved two match points and fought back before a medical timeout for Raducanu’s bloodied knee delayed the match at the most inopportune of moments. Fernandez seemed furious but Raducanu composed herself, saved two break points and clinched victory in fittingly clinical style with an ace. Of the medical timeout, the teenager said: “I didn’t actually want to stop because I thought it would disrupt my rhythm. But I couldn’t play on. I wasn’t allowed to because my knee was gushing with blood. I guess I just went over and was really trying to think what my patterns of play were going to be, what I was going to try to execute. “Going out there facing a break point after a two or three-minute disruption isn’t easy. I think I managed to really pull off the clutch plays when I needed to.” As well as a cheque for £1.8m, dwarfing her previous career earnings of £220,000, Raducanu collects 2,000 ranking points and will soar up the standings from 150 to 23. She has gone overnight from a rank outsider to one of the top names in the game. “I don’t feel absolutely any pressure,” she said. “I’m still only 18 years old. I’m just having a free swing at anything that comes my way. That’s how I faced every match here in the States. It got me this trophy, so I don’t think I should change anything.”
