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.
After Nadal’s final backhand struck the net, Tiafoe was in disbelief as he tried to reckon with the significance of his achievement.
I don’t even know what to say right now. I’m beyond happy, I’m almost in tears,” said Tiafoe during his on-court interview.
