Less than three weeks ago, Emma Raducanu began battling for her place in the US Open main draw.
On Monday, she stumbled across a giant billboard of her face on the streets of New York as she squeezed some sightseeing between appearances on prime-time American breakfast television.
It is this unexpected, unpredictable change in circumstances that has made the 18-year-old's first Grand Slam title front-page news around the world.
Raducanu has not only made British history as the country's first woman to win a Grand Slam singles title in 44 years, but becoming the first qualifier to win a major means she has made tennis history too.
