Mirra Andreeva lived up to the hype and came of age by sealing her maiden Grand Slam title at the French Open at the age of 19.
Eighth seed Andreeva ended the run of 114th-ranked Polish qualifier Maja Chwalinska with a 6-3 6-2 victory at Roland-Garros.
The Russian became the youngest player to win the women's singles title since Monica Seles, who was 18 when she landed her third straight French Open in 1992.
Chwalinska was attempting to become the first qualifier to capture the title in Paris.
Russia's Andreeva, who lives and trains in France, may not have had the majority of the crowd behind her - perhaps in part because of the political landscape and perhaps because of her opponent's underdog status - but there is no doubt she is a phenomenal talent and a worthy Grand Slam champion.
When a final winner landed in the corner, Andreeva, who is also the first Russian female grand slam singles champion since Maria Sharapova here in 2014, dropped to her knees in celebration.
"You're a very tricky opponent. Wouldn't want to play you one more time. No, it's okay. I hope we play âmany more finals in the future," Andreeva said during the trophy ceremony.
"It was a big dream of mine to â win this tournament. I can't believe that I'm holding this trophy."
Andreeva added: "I want to thank myself for believing in myself, giving 100 per cent even when it's been tough, trying everyday to be better as a person and a player, believing I can do this, fighting so many demons inside of me.
"Only I know how tough it was for me and how nervous I was these past two weeks, so thanks to me for working so hard and giving my best."
Attention ahead of the match had understandably been dominated by the remarkable run from qualifying to the final of 24-year-old Pole Chwalinska, who vast swathes of those in attendance appeared to be supporting.
Nine successive victories put her one win away from matching Emma Raducanu's unprecedented achievement in New York in 2021.
Chwalinska is no teenage dreamer, though, having battled away on the lower reaches of the tour for years, including struggling with depression, without ever making the top 100 or beating a top-50 player.
She arrived in Paris in good form but not even in her most fanciful moments could she have imagined how things would play out over the next three weeks.
Four successive victories over top-50 players, including Andreeva's doubles partner Diana Shnaider in the last four, made Chwalinska at 114 in the world the lowest-ranked finalist since the inception of the rankings in 1975.
She will climb to 21 on Monday, and Wimbledon organisers will look churlish in the extreme if they do not give her a wild card for a tournament where she would now be seeded.
Actor Brad Pitt was among those sat courtside for a match no one would have predicted and from which it was hard to know what to expect.
There could not have been a bigger contrast between this cat-and-mouse contest and the power battle at the Australian Open final that Elena Rybakina won against Aryna Sabalenka.
There were clearly nerves at play on both sides, while the wind was an extra complicating factor, and some of the early exchanges were so tentative they were more club tennis than grand slam final.
Chwalinska was the first player to hold serve in the fifth game, prompting wild celebrations from her army of red-and-white clad fans, but slowly Andreeva began to get a handle on how to combat the unorthodox patterns of her opponent and four games in a row gave her the opening set.
Left-hander Chwalinska's unusual use of spins and lack of pace had bamboozled previous opponents but Andreeva was a step up in class, the first top-10 player the Pole had ever faced, and she began to look more and more comfortable.
Andreeva was perhaps the worst opponent for Chwalinska given her high tennis IQ and the variety she also has in her game, and the Polish flags stayed draped on knees as the games ticked away.
Chwalinska finally stopped the run against her at nine games and, when a nervy Andreeva blew her first chance to serve out the victory, a glimmer of hope appeared, but a final backhand from the Russian clinched the title.
"Congratulations âto Mirra, such an incredible player, so young and so talented, it's so annoying. Congratulations to your team as well, âfor an amazing job, and all the best for the future," said Chwalinska.
"I wish we could see a better match today, but Mirra is too good, so I guess it's her fault. I tried my best. I'm âsorry. I will never forget these three weeks, Paris âwill forever be in my heart. Merci."
In men's doubles, top-seeded Marcel Granollers and Horacio Zeballos retained their title with a 6-4 6-2 win against Harri Heliovaara and Britain's Henry Patten.
Three-time champion Alfie Hewett finished runner-up in the men's wheelchair singles final as world No 1 Tokito Oda claimed his fourth successive title after a 6-3 6-3 win.
Hewett and Gordon Reid did take their Grand Slam men's doubles title tally to 24 after the top seeds claimed a record-extending seventh successive French Open title with a 6-2 6-3 victory against Spain's Martin de la Puente and Stephane Houdet of France.
