After playing with the Indianapolis Clowns of the Negro American League and in the minor leagues, Aaron started his major league career in 1954.

He played 21 seasons with the Boston, Milwaukee and Atlanta Braves in the National League, and his last two years (1975–76) with the Milwaukee Brewers in the American League. His most notable achievement was setting the MLB record for most career home runs at 755.
