Emma Raducanu is moments away from taking to the court in the final of the US Open as she hopes to make history as the first British woman to win a major in 44 years.
The 18-year-old from Kent is taking on Leylah Fernandez, 19, in front of 24,000 fans at Arthur Ashe Stadium in New York - the first all-teenage women's final at Flushing Meadows in 22 years.
On the line is a prize cheque for £1.8million - more than eight times Raducanu's current career earnings - as well as 2,000 ranking points, which would move the teenager up from her current standing of 150 to 23.
Raducanu, the first qualifier to ever reach a Grand Slam final, is being backed by millions at home tonight after she won widespread praise for her semi-final performance, including from the Duke and Duchess of Cambridge, Prime Minister Boris Johnson and footballer Marcus Rashford.
She faces tough opposition in Fernandez who has been a giant slayer at Flushing Meadows, knocking out defending champion Naomi Osaka, former US Open winner Angelique Kerber, fifth seed Elina Svitolina and second seed Aryna Sabalenka.
Despite her sensational run, bookmakers had Raducanu chalked up as the favourite at 4/7 - meaning a £10 bet would return just £15.70.
The match is being shown live on Channel 4 after a last-minute deal said to be worth £30 million was struck with Amazon amid feverish anticipation among the tennis-loving British public.
A ceremony to mark the 20th anniversary of 9/11 took place before the pair got underway, with a massive Stars and Stripes flag unfurled to a performance of the Star Spangled Banner. A '9-11-01' stencil has been painted on the court.
