Teenage dreams

Coco Gauff, who is still only 17, reached her first grand slam final alongside fellow American Caty McNally in the women's doubles and then spoke about the impact of Emma Raducanu and Leylah Fernandez vying for the singles trophy.

"Every tournament I believe I can win the tournament," she said. "Obviously, with Leylah and Emma, I guess it makes the goal seem closer because they're close in age to Caty and I, too. So it definitely shows that we're not too far off."

Brit watch

Salisbury is starting to make grand slam finals a habit. After winning the men's doubles title, the 29-year-old reached the final of the mixed with American Desirae Krawczyk. The pair lifted the title at the French Open this year. Wheelchair star Alfie Hewett has never failed to reach the men's singles final in New York and he did so again, while he and Gordon Reid are going for an eighth successive slam title in the men's doubles.

Who's up next?

All eyes will be on the women's final, where 18-year-old Emma Raducanu looks to become the first British woman to win a grand slam singles title since Virginia Wade in 1977.
