Phuoc clocked a time of 50.80secs in the men's 100m freestyle to finish second. The gold medal belonged to the hosts' Yeo Kai Quan with a time of 50.66.

Teammate Pham Thanh Nguyen also competed in this discipline, but with little success.
On Wednesday, teenager Nguyen Thi Anh Vien won two gold medals in the women's 200m backstroke and 200m individual medley.VNS
