World number one Novak Djokovic secured his 76th tour-level title by beating John Millman in straight sets at the Japan Open.
The Serbian had not played since he retired with a shoulder injury in the fourth round of the US Open last month but, on his tournament debut in Tokyo, stormed to a 6-3 6-2 win over the Australian.
Djokovic managed to break Millman's serve at the second opportunity in the first set to take a 3-1 lead, which his opponent struggled to recover from.
In the second set, Djokovic took an early break point in Millman's first service game after forcing an error from the world number 80.
Towards the end of the match, Millman made more errors as Djokovic continued to serve well, losing just four first-serve points.
The 32-year-old won in one hour and nine minutes and did not drop a set in the tournament.
Thiem charges to China victory
At the China Open, Dominic Thiem fought back from a set down to beat Stefanos Tsitsipas 3-6 6-4 6-1 to secure his fourth title of the season.
Top seed Thiem broke in the second game of the deciding set to take momentum away from the world number seven, before going ahead to take the third set for the loss of just one game.
The pair met five times last year, with Thiem winning three as his record over the Greek continued.
