Emma Raducanu ended Britain's 44-year wait for a women's Grand Slam singles champion as she beat Leylah Fernandez to win the US Open in the most thrilling style.
The 18-year-old ended her scarcely believable run in New York with a 6-4 6-3 win over her 19-year-old Canadian opponent in a high-quality final.
Raducanu threw herself to the floor in disbelief as she fired down an ace to conclude what has been the most remarkable journey.
Raducanu served for the match at 5-3 but cut her leg as she went break point down, leading to a medical time-out and a clearly irritated Fernandez expressing her frustration to the match official.
However, Raducanu shrugged off the delay, saving a further break point before closing out her third championship point.
The two shared a warm hug before Raducanu headed up the stairs at Arthur Ashe Stadium to celebrate with her support box.
Raducanu was cheered on by an emotional Virginia Wade, who was the last British woman to win a major trophy at Wimbledon in 1977.
Emma Raducanu is the first qualifier to win a Grand Slam and has done so without dropping a set
"It means so much to have Virginia Wade here and also Tim Henman," Raducanu said in her on-court speech.
"They are British icons and for me to follow in their footsteps gave me the belief I could do it."
With the victory, Raducanu becomes:
• The first British female winner at Flushing Meadows since Virginia Wade in 1968
• The first qualifier in the Open era to win a Slam
• The youngest women's Slam champion since Maria Sharapova at Wimbledon in 2004
• The youngest Briton to win a Grand Slam title
The first woman to win the US Open without dropping a set since Serena Williams in 2014
She will take home £1.8m in prize money, rise to 23 in the world rankings and will become the British number one on Monday.
Raducanu will also know that she has starred in one of the biggest moments in British sporting history - and captured the imagination of the fans at home and in New York.
Astonishing. Ridiculous. Meteoric. Unbelievable. Take your pick - but no word can ever really sum up what Raducanu has achieved.
Two weeks ago, Raducanu had a flight booked back to the UK, just in case she did not come through qualifying in New York. Seventeen days later, she has lifted the trophy in front of a rapturous crowd.
Raducanu did not just come through qualifying: she dominated it. The most games she lost in one set in her entire run in New York - five - came in the second round of qualifying.
It is not just that Raducanu has kept on winning, but she has done it with such dominance. She did not drop a set en route to the final, despite meeting Olympic champion Belinda Bencic and in-form Maria Sakkari on the way.
In the big moments, she has held her nerve, trusting in her power and serve, even when she saw two championship points go by in the final.
This is someone who, two months ago, was collecting her A-Level results. She only made her WTA main-draw debut in June. All this has happened so quickly, and yet not once has Raducanu not looked like she belongs.
With all the attention on Raducanu after Wimbledon - as well as questions from some about her mental toughness - she could have easily been overwhelmed.
Instead, she trusted in herself, hired a new coach in Andrew Richardson and went to America to play in the various events.
No-one could have seen this coming; not the ease with which Raducanu would brush her opponents aside, or the calmness with which she would approach every match.
But Raducanu always believed. And she will leave New York as the US Open champion.
