Joseph Isaac Schooling of Singapore became the country's first-ever Olympic gold medalist after winning the 100m butterfly event in 50.39s at Rio 2016 on 13 August, beating American legend Michael Phelps, South Africa's Chad le Clos and Hungarian Laszlo Cseh who all bagged silver with 51.14s.

Schooling's time smashed the Olympic Games record of 50.58s, clocked by Phelps at Beijing 2008, who had won the 100m butterfly at the past three Olympics. The win by the Singaporean also marked the first time a swimmer from Southeast Asia had bagged a gold.
