Definitions for "Forkball"
A pitch thrown by placing the ball between the first two fingers, usually resulting in a sinking ball.
The forkball is a type of pitch in baseball. Related to the split-fingered fastball, the forkball is held between the first two fingers and thrown hard without snapping the wrist. The forkball differs from the split-fingered fastball, however, in that the ball is jammed deeper between the first two fingers and that the ball starts to dive late comparing to that of splitter.
