“The Spitter” spitball sports art painting by artist John Robertson is 50″ x 70″ acrylic on unstretched canvas.
A spitball is an illegal pitch in which the ball has been altered by the application of saliva, petroleum jelly, or some other foreign substance. The pitch causes the ball to move atypically due to the altered wind-resistance and weight on one side of the ball. Alternative names for the spitball are spitter, mud ball, shine ball and emery ball, although technically, an emery ball is one where the ball has been abraded in much the same way that the original cut ball had been physically cut. The altering of the ball’s state by the use of artificial substances such as sun block, dirt or degradation by fingernails or other hard substances is illegal tampering.
