Carr made two first-class appearances during his cricketing career, the first coming for Essex in the 1960 season, following two seasons of action in the Second XI, with whom he was a first-team player during 1959. Carr's second and final first-class appearance came four years later, playing for Transvaal in an innings defeat against the MCC.
