Osaka’s comeback marked the first time in 26 years the women’s final in New York has been won by the player who lost the first set. The last woman to achieve the feat was Arantxa Sanchez Vicario, who defeated Steffi Graf in 1994 having also dropped the opening set 6-1.
Mariah Carey hits Flushing Meadows
Thank you @USOpen for this amazing TV Premiere of my song "Save The Day". Couldn't be more honored and moved to share the message of the song with these incredible female champions. 🎾❤️ #SaveTheDayhttps://t.co/e7nL7UPPZF

In this most strange of years, opening the women’s final with Mariah Carey sitting in a car inside the Billie Jean King National Tennis Centre and singing to footage of the greats of women’s tennis made perfect sense. Maybe.
Up next
Dominic Thiem will look to make it fourth time lucky in grand slam finals when he takes on first-time finalist and good friend Alexander Zverev for the men’s title.
