Despite the rarity of women's nicknames in occupations where nicknaming has been popular for men, no analysis has systematically explored these gender differences. This study draws hypotheses from a traditional socialization perspective and Rosabeth Moss Kanter's structural perspective to compare nicknaming practices among female professional baseball players with nicknaming practices that have been consistently found among male professional baseball players during the same time period. Data extracted from a survey of female baseball players who played professionally during the 1940s were utilized to contrast the importance of gender with occupational experiences as determinants of nicknaming practices. The results support Kanter's structural perspective, which suggests that the nicknaming practices of women are a function of their position in the organizational structure and their immediate situation.
