Of the two sisters, Kit is portrayed as someone who yearns to use pro baseball to get away from life in rural Oregon. Dottie, meanwhile, is content to stay home while her husband fights overseas in World War II, but she is a naturally more talented ballplayer than Kit. In fact, Jon Lovitz's scout character initially only wants to recruit Dottie for the women's pro league. Kit is included only because she managed to change Dottie's mind about participating in the first place (via YouTube).
Dottie becomes the face of the league with her acrobatic catches behind home plate and high-quality play, while Kit struggles to achieve the prominence she hoped for in her older sister's shadow. Dottie recognizes how this affects her sister and requests a trade for herself so Kit can shine as the Rockford Peaches' star — but Kit is actually traded to the Racine Belles as a result. The siblings argue when the trade happens, leaving Kit and Dottie on bad terms as the season ends and the World Series approaches.
Rockford and Racine meet in the World Series, and Kit finally bests her older sister. She scores the championship-winning run by knocking over Dottie at home plate, dislodging the ball from her hands. While Kit finally gets her moment as a star, whether or not Dottie drops the ball on purpose to let Kit win has been hotly debated over the years.
