Schooling enlisted as part of a two-year period of national service which was twice deferred following the Rio 2016 and Tokyo 2020 Olympics, where he earned men’s 100 metres butterfly gold at the former.

He clinched a fifth consecutive SEA Games gold in the event in Vietnam by clocking 52.22sec in the final.

The result saw Schooling move up to third on the all-time SEA Games medals list with 29 gold medals.

Only fellow Singapore swimmers Joscelin Yeo and Patricia Chan have won more titles at the Games, winning 40 and 39 gold medals, respectively, during their careers.

Yulo added the men’s vault title to triumphs in the individual all-around, floor and rings events.
