サチェル・ペイジ
In 1934, before a barnstorming match-up, Dizzy Dean was heard on the radio saying that "Satchel Paige has no clue how to throw a curve." In actuality, Paige had been practicing and perfecting his curveball in secret for many years. When Dean came up to bat, Satchel Paige struck him out with nothing but curveballs—officially adding the pitch to his repertoire. Paige could throw a variety of curveballs at different speeds and arm angles.
