American swimmer Caeleb Dressel has claimed the first individual Olympic gold medal of his career.
Dressel held off the defending Olympic champion, Australia’s Kyle Chalmers, with a furious sprint to the wall.
The winning time was an Olympic record of 47.02 seconds. Dressel beat Chalmers by a mere six-hundredths of a second, leaving the 2016 winner with a silver medal this time.
The bronze was claimed by Russia’s Kliment Kolesenikov.
The first three gold medals of Dressel’s career were all in the relays.
