Women played a crucial role during WWII for the United States by stepping up and filling positions for the men that left for war. They kept America's pastime, baseball, alive with the All-American Girls Professional Baseball League (AAGPBL). It was a women's professional baseball league that existed for twelve seasons based in Midwestern cities. The AAGPBL gave women the opportunity to play professional baseball. The league became very popular, and women were able to show the world that they were just as talented as the men.
