Hong Kong's tennis star Coleman Wong continued his run in the men's singles at the National Games with a straight-sets victory in the second round on Sunday.

The No 2 seed took one hour and 16 minutes to win 6-4, 6-3 against Hubei's Chen Ye, while serving nine aces at the Hengqin International Tennis Centre.

Wong, currently ranked 145th in the world, will return to the court on Monday for his third-round match.

However, it was a different story for teammate Nicholas Cheng, who lost in the second round with a defeat of 3-6, 0-6 to fourth-seeded Zhou Yi of Guangxi.
