World number one Novak Djokovic beat John Millman to mark his return from injury by winning the Japan Open.

The 31-year-old won 6-3 6-2 in the final in Tokyo to claim a fourth title of the year and a 76th of his career.

It was the Serb's first tournament since he withdrew from the US Open in September with a shoulder injury.

Djokovic needed just 70 minutes to see off 30-year-old Australian world number 80 Millman and did not drop a set throughout the tournament.
