Djokovic breezes into quarters

Novak Djokovic steamed into the quarter-finals of the US Open with a 6-2, 6-1, 6-4 victory against 84th-ranked Briton Kyle Edmund. Edmund, playing in a Grand Slam fourth round for the first time, barely got a look-in during the first two sets against the world number one and defending champion, who booked a last-eight meeting with ninth-seeded Frenchman Jo-Wilfried Tsonga, a 6-3, 6-3, 6-7 (7/9), 6-2 winner over American Jack Sock.
