The US Open concluded yesterday (September 10), with Novak Djokovic winning the men's singles title, with Coco Gauff winning the women's singles on Saturday (September 9).

The tournament's main-draw attendance was a US Open record of 799,402, including sell-outs in all 25 sessions in the Arthur Ashe Stadium for the second year in a row.
