Murray qualified for the men's 100 m freestyle at the 2000 Summer Olympics in Sydney by posting a FINA B-standard of 51.97 from the Pan American Games in Winnipeg, Manitoba, Canada. He challenged seven other swimmers in heat four, including three-time Olympic veterans Indrek Sei of Estonia and Carl Probert of Fiji. Murray managed to record his personal best of 51.93, but came up short in second place by almost six tenths of a second (0.6) behind Probert. Murray failed to advance into the semifinals, as he placed fortieth overall in the prelims.
