In 1920, Major League Baseball declared the "spitball" an illegal pitch. However, a grandfather clause allowed the 17 remaining established spitballers to continue throwing the pitch. At the time of their retirements, the pitch would be banned for good. Burleigh Grimes was one of those 17 pitchers. The moistened ball aided his efforts and provided the force behind four World Series appearances, five 20-win seasons, and four years as the National League complete games leader. Burleigh Grimes played 19 seasons with seven different teams, and in 1964, was elected to baseball’s Hall of Fame.
