NEW YORK (Reuters) - Felix Auger-Aliassime broke through Frances Tiafoe's defences to win 4-6 6-2 7-6(6) 6-4 at the U.S. Open on Sunday in a fourth-round battle between two of the sport's brightest young talents.

Both players came into the tie at Arthur Ashe Stadium on the back of tough five-setters and it was 23-year-old Tiafoe who started the brighter, going up a break after the first game and shutting down all eight of the Canadian's break point opportunities to go up 1-0.
