US Open Tennis

Novak Djokovic of Serbia, Alexander Zverev of Germany and Denis Shapovalov of Canada qualify for the pre-quarter final round of US Open Tennis Tournament.

In the third round match, top seed Novak Djokovic outplayed Jan Lennard Struff of Germany in straight sets by 6-3, 6-3 and 6-1.

Djokovic, a three-times champion at flushing meadows, was never really pushed by the German, who has taken just one set off the Serb in their five career meetings.

Djokovic will be a heavy favourite when he faces 20th seed Pablo Carreno Busta of Spain in the fourth round.

In another third round match, Alexander Zverev beat Adrian Mannarino of France by 6-7, 6-4, 6-2 and 6-2.

Zverev next faces Spain's Alejandro Davidovich Fokina, who defeated Britain's Cameron Norrie 7-6, 4-6, 6-2 and 6-1 in third round.

Meanwhile Denis Shapovalov qualify for the fourth round after beating Taylor Fritz of USA in a thrilling match by 3-6, 6-3, 4-6, 7-6 and 6-2.
