The type of pitch that was banned from baseball in 1920 was the spitball. In the winter of 1919-1920, managers voted to partially ban the spitball, and each team was allowed to designate up to two pitchers who would be permitted to throw spitballs. However, after the 1920 season, the use of the spitball was banned with the exception of a group of 17 existing spitballers, who became legacy spitballers who were allowed to throw the pitch legally until they retired. The ban on the spitball was partially due to the death of Ray Chapman, who was hit in the temple by a pitch thrown by known spitball pitcher Carl Mays during a poorly lit game in August 1920.
