Swimming at the 1972 München Summer Games:

In 1971 Australian Shane Gould had set two world records in this event. But American Shirley Babashoff bested those at the 1972 US Olympic Trials in Chicago in August. Gould took the lead in the final almost immediately and at 100 metres was half-a-bodylength ahead of the American trio of Babashoff, Keena Rothhammer, and Ann Marshall. By 150 metres Gould had open water. Babashoff and Rothhammer would better the Chicago world record, but it would only be good for the silver and bronze medals, as Gould shattered the mark with 2:03.56. Gould would eventually win three golds, a silver, and a bronze in Munich and then retire from swimming in early 1973.
