Emma Raducanu exploits on the court mean she is set to be in huge demand off it and Conrad Wiacek, head of sport analysis at GloblaData, says the 18-year-old will become a "commercial phenomenon".

“By reaching the US Open Final at just 18 years of age, Emma Raducanu will become a commercial phenomenon in the UK," said Wiacek. "Should she win, it is likely her profile will go global.

"With British tennis having a gap at the top of the tree following the decline in Sir Andy Murray’s abilities through injury, the chances are that Emma Raducanu will fill that gap and generate millions through commercial partnerships.

“With just two deals currently in place with Wilson and Nike, Raducanu can expect her earnings potential to grow significantly. Just by renewing her existing deals, Raducanu can expect to be generating revenue in excess of $1m from these two deals alone, while other brands will no doubt be looking at Raducanu as a potential brand ambassador.

“Emma Raducanu may have become the face of British tennis for the foreseeable future.”

Emma Raducanu will become the new British number one when the rankings are updated on Monday, but began her campaign in New York as the world number 150.

Ranked too low to make the main draw, the 18-year-old had to come through three rounds of qualifying and has become the first qualifier to reach a major final.

This evening she will seek to become the first British woman to win a Grand Slam singles title in 44 years, the last person to do so being Virginia Wade at Wimbledon in 1977.

She has already achieved so much in just three months, reaching the last 16 at Wimbledon on her Grand Slam debut and rising from 338 in the rankings to what will be just outside the top 30 when the rankings are updated.

Of course, it has also been a sensational run to the final for Leylah Fernandez, who was handing out cupcakes to celebrate her 19th birthday on Monday and is now a serious Grand Slam contender.

The Canadian world number 73 has brushed aside a series of leading players en route - taking out defending champion Naomi Osaka, fifth seed Elina Svitolina, world number two Aryna Sabalenka and three-time Grand Slam champion Angelique Kerber.

This blockbuster may being played out in New York but it has been a Hollywood-worthy few weeks for Emma Raducanu.

Even the most brazen directors might have felt the tale of the 18-year-old's rise to Grand Slam finalist was too unrealistic, with Raducanu coming through qualifying at Flushing Meadows and winning all six of her main-draw matches so far without dropping a set.

Repeat the feat this evening and she will leave the Big Apple as the US Open champion.
