Hong Kong's Wong Wing Ki won the Badminton World Federation (BWF) Vietnam Open title today with a three-game victory in Ho Chi Minh City.
The number four seed came through against Chong Wei Feng of Malaysia, 21-12, 14-21, 21-13, in a topsy-turvy contest at the Nguyen Du Stadium.
Chong, the 11th seed, had enjoyed a good run to the final but the Glasgow 2014 Commonwealth Games mixed team champion could not clinch the title.
The Hong Kong player was the best ranked in the competition after the first round stage, when third see Wei Nan - his compatriot - was knocked out.
The top two seeds - Hu Yun and Ng Ka Long, both also of Hong Kong - withdrew before a shuttlecock had been hit.
In the women's final at the BWF Grand Prix Gold event, an unseeded affair went the way of Singapore's Yeo Jia Min.
She came through in straight games, beating Japan's Ayumi Mine 21-14, 21-17.
In the men's doubles, Chinese Taipei pair Lee Jhe-huei and Lee Yang came from behind to triumph over Malaysia's Koo Kien Keat and Tan Boon Heong, 18-21, 21-14, 21-7.
The women's doubles title went to Indonesia as third seeds Della Destiara Haris and Rosyita Eka Putri Sari saw off their team-mates Tiara Rosalia Nuraidah and Rizki Amelia Pradipta 21-11, 21-15.
In the mixed doubles, Malaysia's Tan Kian Meng and Lai Pei Jing were crowned as champions after a 21-16, 21-11 triumph against Indonesian pair Alfian Eko Prasetya and Annisa Saufika.
