thumb A gyroball is a rare type of baseball pitch used primarily by players in Japan. It is thrown with a spiral-like spin, similar to bullet from a rifle, or an American football pass. This spin stabilizes the ball in flight, minimizing its deviation from a straight-line path to home plate. The gyroball is sometimes confused with the shuuto, another pitch used in Japan.
