Elena Rybakina cemented her position as world No 1 by dethroning two-time US Open winner Aryna Sabalenka to seal her maiden title in New York last Saturday.
Rybakina won her first US Open, beating top seed and defending champion Sabalenka 6-4 5-7 6-2 on Arthur Ashe Stadium.
The 27-year-old had already been guaranteed to replace Sabalenka at No 1 in the rankings next week.
Sabalenka was looking to become only the third woman to achieve a New York 'three-peat' in the Open era, after Chris Evert and Serena Williams.
Instead she was left sat in her chair, furiously smashing her racket in to smithereens as Rybakina, from Kazakhstan, celebrated a third Grand Slam title.
An ankle injury had threatened to derail Rybakina's campaign even before the tournament started, but she shrugged off those concerns to add the US Open title to her Australian Open triumph this year and Wimbledon success in 2022.
