American Frances Tiafoe stunned Rafael Nadal to hand the 22-time major champion his first grand slam defeat of the season in the fourth round of the US Open.
Nadal was looking for his third slam title of the year after winning the Australian Open and French Open to take the lead in the overall race but he was overpowered by Tiafoe in a 6-4 4-6 6-4 6-3 victory.
No American man has won a grand slam title since Andy Roddick at Flushing Meadows in 2003, by far their longest drought in tennis history.
