in Sydney, Crocker was a member of the gold medal-winning 4x100-meter medley relay team and barely missed winning a bronze in the 100-meter butterfly.
At the

Lars Frölander.
2003 World Aquatics Championships
At the

Matt Welsh, who set the world record. Crocker is best known in these Championships for his world record performance in the 100 m butterfly final. After the semi-finals of the 100-meter butterfly, it seemed Crocker was out of the gold medal position after
Andrii Serdinov and

went under the former world record. However, in the final of the 100-meter butterfly, Crocker swam a 50.98 to become the first man under 51 seconds and win the gold medal. When Crocker saw the time after the race, he thought the world record belonged to Phelps. Crocker earned his final medal, a gold, in the 4×100-meter medley relay. The American team recorded a time of 3:31.54 to beat the former world record set in 2002.
2004 Athens Summer Olympic Games

overtook him at the very end of the 100-meter butterfly to win the race by 0.04 seconds. Traditionally, the Olympian who places highest in an individual event will be automatically given the corresponding leg of the 4×100-meter medley relay for the finals swim. This gave Phelps an automatic entry into finals for the medley relay but he deferred that spot to the world record-holder and swam the butterfly leg in preliminary heats instead. Crocker had swum a slow leg leading off the 4×100-meter freestyle relay final, which may have cost the Americans a better medal, so Phelps' gesture gave Crocker a chance to make amends in a final. Crocker and the American medley team went on to win the event in world record time. (Phelps still received a gold, since he had swum in the preliminary heat of the medley relay.)
2005 World Aquatics Championships

At the
2005 World Aquatics Championships, Crocker won a total of three medals, two golds and one silver medal. In his first event, the 50 m butterfly, Crocker won a silver medal finishing behind South African
Roland Schoeman, who set the world record. In the final of the 100 m butterfly, Crocker recorded a time of 50.40 to beat his own world record of 50.76 and win the gold medal. Crocker also handed Michael Phelps one of the worst losses in his career when Phelps finished over a second behind. With this win, Crocker was awarded a spot in the 4 × 100 m medley relay. Crocker did not disappoint and swam the butterfly leg in 50.39. The American team went on to win the gold medal.
2007 World Aquatics Championships
At the
2007 World Aquatics Championships, Crocker won two silver medals. In the 50-meter butterfly, Crocker won a silver medal finishing behind Schoeman. In the 100 m butterfly final, Crocker finished second to Phelps 50.82 to 50.77. In the heats of the 4×100-meter medley relay, Crocker dove in too early on an exchange, causing the disqualification of the American team.
2008 Beijing Summer Olympic Games
Crocker competed in his third Olympics as a medal contender for his signature 100-meter butterfly. Many felt Crocker's career was on a slide due to a poor showing in the Olympic trials and having not broken the 51-second barrier in over 12 months. Crocker finished in a tie for third in the semi-finals, behind Australia's
Andrew Lauterstein. In the finals, he finished fourth behind teammate Phelps,
Milorad Čavić, and Lauterstein, beating Kenyan swimmer
Jason Dunford. He missed the medal stand by one hundredth of a second. Despite not earning a medal in his signature event, Crocker was given the opportunity to swim for the 4×100-meter medley relay in the preliminary heats. He earned a gold medal for his contribution.
2011 return to drug testing pool
In the third quarter of 2011, Ian Crocker returned to the
USADA drug-testing pool. This fueled speculation that he might be considering a return to competitive swimming after more than three years away from the sport.
