Competing in his first and only Summer Olympics, 20-year old Dawood Yosuf Mohamed Jassim was the youngest man to compete on behalf of Bahrain at the Sydney Games. He received a universality place from the world governing body of swimming, FINA, because his entry time of one minute and 10 seconds was 17.41 seconds slower than the "B" (FINA/Olympic Invitation) time needed to attain automatic qualification for the men's 100 metre freestyle. In the first round of Jassim's contest, he was drawn to swim in the second heat on 19 September. He completed the race in a time of one minute and 2.45 seconds, which put him seventh and last of all the swimmers in his heat. Jassim placed 70th out of 71 finishing athletes overall and this meant he did not progress to the semifinals since only the top 16 were permitted to advance to that stage.
