Kathryn Johnston Massar

Kathryn "Tubby" Johnston Massar ( Johnston) was the first woman to play in a Little League Baseball game, which happened in 1950. She joined disguised as a boy and using the name Tubby Johnston, but later was known to be a girl and was still allowed to play. Johnston was from Corning, New York, and played first base for the King's Dairy team.

Tubby's Rule
When the season had ended, a Little League meeting was held. It was decided that girls would be banned from Little League Baseball, which was known as Tubby's Rule. Later, in 1974, due to a lawsuit brought on behalf of Maria Pepe by the National Organization for Women, the New Jersey Superior Court decided that Little League Baseball must allow girls to play. In the final week of December of that year, President Gerald Ford signed a bill that opened Little League Baseball to girls.
