At the 1991 World Aquatics Championships in Perth, Western Australia, Haislett won the 100-meter freestyle, and swam the anchor legs for the winning U.S. teams in the 4×100-meter freestyle and the 4×100-meter medley relays, ending the East German women's eighteen years of overwhelming dominance in the 100-meter freestyle at the world championships.
