U.S. Open | Tiafoe ends Nadal’s 22-match Slam streak in fourth round

Frances Tiafoe’s vision was blurry from the tears. He was thrilled — overwhelmed, even — when the last point was over and it hit him that, yes, he had ended Rafael Nadal’s 22-match Grand Slam winning streak on Monday and reached the U.S. Open quarterfinals for the first time.

Maybe one day, went the dream, a college scholarship would come of it.

“It wasn’t anything supposed to be like this,” Tiafoe said on Monday evening, hours after by far his biggest victory.

He is the youngest American man to get this far at the U.S. Open since Andy Roddick in 2006, but this was not a case of a one-sided crowd backing one of its own.
