Denis Shapovalov's dream run at the US Open continued on Friday, at the expense of Kyle Edmund.
Edmund suffered an apparent neck injury midway through the third set of his third-round match against Shapovalov, and retired one game into the fourth after being rendered immobile and dropping five straight games.
With the win, the 18-year-old Shapovalov becomes the youngest men's player to reach the second week at the US Open since Michael Chang did it at 17 back in 1989. He's the youngest man to reach the fourth round at any Slam since Marat Safin did as a slightly younger 18-year-old at the 1998 French Open.
It was a disappointing way to go out for Edmund, who came into the tournament on the heels of a semifinal run in Winston-Salem and continued that fine form by charging through the first two rounds without dropping a set.
At the time of his injury, the 22-year-old had played the ascendant teenager to a draw. The two had split the first two sets and were on serve in the third, with hardly anything to separate them. Edmund had done a great job stretching Shapovalov out wide, while making hardly any mistakes. The match could've gone either way.
But a visit from the trainer couldn't cure what ailed Edmund, and Shapovalov rolled on with a second straight victory on Arthur Ashe Stadium court. He'll play Pablo Carreno Busta for a spot in the quarterfinals.
