Caleb Dressel, an American swimmer called the 'second Phelps', added two gold medals to his first five gold medals in this competition.

Dressel then added a gold medal in the 400m medley relay with a world record of 3:26.78.

It is the first five gold medals in the event following the 400m relay, 100m freestyle and 100m butterfly.
