Jack Draper produced a brilliant display to reach the US Open quarter-finals with a straight-set win over Tomas Machac.
The Brit stormed to a 6-3 6-1 6-2 victory in just an hour and 44 minutes as he booked his place in the last eight of a Grand Slam for the first time.
Czech Machac had won the only previous match between the pair but, after a strong start, was outclassed by a laser-focused Draper on Louis Armstrong Stadium.
Draper, the 25th seed, will face the winner of the all-Australian contest between 10th seed Alex de Minaur and Jordan Thompson in the next round.
