Later the same night, Thorpe anchored the Australians to a historic victory in the 4 × 100 m freestyle final, the first time the United States had lost the event. Thorpe set an Australian record relay split of 48.55 s. Even taking into account a 0.6–0.7 s for a flying relay start, his split time was almost 1 s faster than his individual best of 49.98 s. It was to be the first of many occasions in which he would anchor the Australian relay teams to victory over the Americans, with splits consistently faster than his equivalent individual times. The following night, in the semi-finals of the 200 m freestyle, Thorpe broke Hackett's world record by 0.33 s, clocking 1 min 46.34 s. The next day in the final, he again broke the record, lowering it to 1 min 46.0 s. He finished his competition by leading off the 4 × 200 m freestyle team with Klim, Hackett and Bill Kirby to victory. Their time lowered their own world record by more than three seconds, completing Thorpe's fourth world record in four nights.
