Kyle Edmund's run at the US Open came to an end as world number one Novak Djokovic showed he is back to his best with a 6-2 6-1 6-4 fourth-round win.
World number 84 Edmund, 21, defeated two seeds to reach the last 16 of a Grand Slam for the first time.
But the Briton was outclassed from the start by defending champion Djokovic.
Edmund's defeat means Andy Murray is the last Briton left in the singles while Djokovic goes on to face France's Jo-Wilfried Tsonga in the last eight.
Djokovic showed no signs of being rusty despite only completing six games in the last two rounds because of injuries to his opponents.
