At specific moments in history, women publicly entered the masculine realm of baseball to advance female suffrage in the United States. Girls and women took to the field in the nineteenth century, enjoying newfound bodily freedoms and disrupting Victorian constraints. While their performances may not have always translated into explicit suffrage activism, their athleticism demonstrated strength at a time when many people used women’s supposed weakness as an argument against their political enfranchisement. However, as the popularity of baseball increased at the turn of the century, the number of female ballplayers decreased. Activism in the sport therefore changed. In the mid-1910s, suffragists advertised at men’s baseball games. The women recognized the value of promoting suffrage through sport; yet, they also acknowledged that by entering ballparks, they entered a male space. Suffragists therefore exhibited conventional White gender norms to avoid aggrieving male voters. Women’s different engagements with baseball, as either players or spectators, had varying consequences for women’s political and sporting emancipation. Women’s physical activism in baseball demonstrated female prowess and strength in sport, but only abstractly advanced women’s political rights; suffragists’ promotional efforts through men’s baseball more directly influenced the eventual passage of the Nineteenth Amendment, but their actions supported women’s position on the sidelines.
