Frances Tiafoe took an enormous step towards fulfilling his great potential as he pulled off by far the biggest win of his career, upsetting the second seed Rafael Nadal 6-4, 4-6, 6-4, 6-3 to reach the US Open quarter-finals for the first time.
In front of a rowdy home crowd at Arthur Ashe Stadium, the 22nd seed became the first man to beat Nadal on court in a grand slam this year. It also marks the first time since Wimbledon 2017 that Nadal has lost before the quarter-final stage of a grand slam.
