Medal summary
Singapore once again proved to be a force to be reckoned with in the swimming events. Even with the home crowd supporting Malaysia due to the location of the games, they were unbeatable to win all 6 relays. Quah Jing Wen, being in her second SEA Games, won 2 individual gold medals, beating the favorite Nguyễn Thị Ánh Viên of Vietnam in the 200 m butterfly and her sister Quah Ting Wen in the 100 m butterfly. She also combined with her sister to emerge champion in the 3 relays. The Vietnamese queen took 8 gold medals, similar to her achievement in 2015. Welson Sim won the 200 and 400 m freestyle but was unable to take the third gold in the 1500 m freestyle where two Vietnamese proved too strong and the Malaysians managed a disappointing 4th in their home ground.
