Tiafoe Stuns Nadal at US Open quarterfinals

American Frances Tiafoe stunned four-time champion Rafael Nadal 6-4, 4-6, 6-4, 6-3 on Monday at the US Open to reach his second Grand Slam quarter-final

"I felt like the world stopped," Tiafoe said. "I couldn't hear anything for a minute."

Tiafoe found himself "losing it in the locker room" when he saw that NBA superstar LeBron James gave him a Twitter shoutout

The pumped-up 24-year-old played fearlessly throughout the three-hour, 31-minute thriller on Arthur Ashe Stadium

First American man to reach the last eight in New York since John Isner in 2018

Nadal was 31-2 in majors against Americans entering Monday's match and had won 27 straight since losing to James Blake in 2005

Nadal was chasing his fifth title in New York and a record-extending 23rd Grand Slam crown this fortnight

However, his defeat has opened the World No. 1 door for #NextGenATP Spaniard Carlos Alcaraz and Norway’s Casper Ruud
