He started out as an infielder but was switched to outfield in 1983 due to his superior speed and frequency of errors (56 in 127 games in 1981 at shortstop for the Nashville Sounds). In 1982, Nixon stole 107 bases in a combined season between the AA level Nashville Sounds and the AAA level Columbus Clippers.
