Ben and NCR's Youth correspondent Alex Gruskin discuss Ben Shelton's big win Tuesday night over Frances Tiafoe in the US Open quarterfinals, a big result both within the American tennis ladder and in the big picture of the ATP generations game.

And when did the buzz about Shelton, who seemed to come out of nowhere, first start?
