American Frances Tiafoe played the match of his life to beat second seed Rafa Nadal 6-4, 4-6, 6-4, 6-3 in the fourth round of the U.S. Open on Monday.
It was the first time this year that Nadal, who had been chasing a record-extending 23rd Grand Slam title, has been beaten in a major.
Tiafoe covered his face with his hands as he soaked up the cheers from a packed house at Arthur Ashe Stadium, after breaking Nadal for a fifth time to claim arguably the biggest upset of the tournament.
