Raducanu made a serveess on her third match ball, threw the racket and lay on her back and took in the moment before she ran to the net and hugged her opponent.
- This is the beginning of something huge, says Eurosport's commentator Maria Strandlund-Tomsvik about both players' future careers.
The two teenagers, both born in 2002, met for the first time as twelve-year-olds.
Both players' path to the final has had a fairytale shimmer over it and the final is perhaps the most unlikely ever played in the tournament's history.
After Fernandez saved two match points at 5-2 in the second set, the atmosphere in the arena was electric with standing ovations and the audience in ecstasy.
When Raducanu served for the match at 5-3 and the position 30-40, she slipped on the track and scratched up a bleeding wound on her left lower leg and was forced to a medical timeout on the track for a few minutes.
Meanwhile, Fernandez had a heated discussion with the referee.
Fernandez had two game balls to break back to 4-5 but Raducanu was able to get together.
Raducanu won the first set after deciding on the fourth set ball.
She shouted out her joy and turned to her own box.
A couple of hours before the match, the news came that it would be shown on public television in the UK, where Raducanu created tennis hysteria.
Fernandez's father, Jorge, who is also her coach, chose to stay at home and watch the match on TV.
He is superstitious and did not want to bring bad luck with him.
The match was played on the 20th anniversary of the 9/11 attacks in New York.
Artist Daphne Rubin-Vega sang the American national anthem accompanied by strings.
Meanwhile, the center court was filled with a giant American flag.
