Emma Raducanu says she is on her "own journey" after sensationally reaching the semi-finals of the US Open.

Raducanu's 6-3 6-4 win over Belinda Bencic – her first career top-40 opponent – saw her become the first qualifier in the Open Era to advance to the last four at Flushing Meadows, the 18-year-old doing so without dropping a set.

She also became the lowest-ranked player in history (150) to make this stage of the tournament, with Kim Clijsters in 2009 and Billie Jean King in 1979 achieving the same feat having been unranked.

Raducanu, who will face either Karolina Pliskova or Maria Sakkari for a place in the final, said: "I have an absolutely amazing team. I have a team back home who could not be here. I am sure they are watching, I hope!

"Thank you so much everyone. I wish you could be here with me but everything we have been working for has shown here.

"To have so many young players here doing so well shows how strong the next generation is. Everyone is on their trajectory, so I am just here doing what I can control, and it is my own journey."

Raducanu grew into the contest after being immediately broken to love and trailing 2-0, proving particularly robust on her opponent's serve.

Bencic landed 61 per cent of her first serves yet managed only a single ace. The Olympic champion was made to work for the 23 points she won on her first serve and then took just nine of a potential 21 on her second.

Raducanu, who managed six aces of her own, added: "Of course, playing Belinda, she is such a great opponent and is in great form, she hits the ball so hard, I had to adjust and adapt and it was a really tough match.

"I am so happy to come through and thank you so much for all your support today.

"It was 0-30 in my last couple of service games so to hold was pretty big, it was one point at a time and trying to focus on what I can control.

"Belinda was going to fight to the end but I am really pleased to come through that."
