The third round of the US Open kicks off with notable matches featuring top players. Defending men's champion Novak Djokovic faces Alexei Popyrin, while women's champion Coco Gauff meets Elina Svitolina. An all-American clash sees Ben Shelton and Frances Tiafoe in a rematch of their last year's quarter-final. Shelton, having won both prior encounters, is ready for another tough battle, while Tiafoe anticipates a challenging but exciting match. Djokovic aims for his fifth US Open title but struggles with his serve, and Gauff plans to bring her best against Svitolina. Barbora Krejcikova, the Wimbledon champion, was ousted in the second round by Elena-Gabriela Ruse.
