Emma Raducanu’s previous best ranking was world number 869
The United States Tennis Association awarded Emma Raducanu’s $200,000 (£154,000) tournament winnings to the city of Krasnodar in Russia.
Sixth seed Raducanu beat former world number two Belinda Bencic of Switzerland in the final to earn victory and was asked after the match if it had been an “easy match”.
She replied: “Well, it wasn’t that easy, you know, but I feel really proud to win the tournament.
“Because this is a new thing for me, and it felt really great.”
Raducanu earned over $200,000 (£154,000) for her victory
Raducanu, 27, beat Elena Vesnina in the first round, Nole-Ayna Jankovic in the second and Eugenie Bouchard in the quarter-finals.
The former world number 869 will now move up to 54th in the rankings and will take on 17th seed Madison Keys in the semi-finals of the Samsung Open.
“Madison has had a great start to the year. She’s really been hitting the ball very well,” said Raducanu.
“She’s a really good player and to play her is going to be a really exciting match. We’ve seen a lot of good tennis, so hopefully we’ll see a good match.”
Other players affected by the rules in Krasnodar were two players from Andorra.
Nour-Eddine Geffrard beat Yafan Wang 4-6 6-3 6-1 but her winnings will be split between Andorra and USTA because of the distribution of prize money in the country.
In another first-round match, Andorra’s Ana Havranek beat Johanna Larsson 6-1 6-1 in the second round.
Fazel Atrachali beat Patrick Kypson 6-2 7-6 (7-3) while 16th seed Alex Bogomolov Jr beat Ivo Karlovic 6-7 (6-8) 6-3 6-4.
