Moir, the South African junior champion in 1980, played collegiate tennis while at Auburn University and was a member of the team that won the Southeastern Conference in 1983. He turned professional at the end of the year.
Playing as a qualifier, Moir managed to reach the third round of the US Open in 1984.
