Illegal Pitch

Illegal Pitch


It is illegal for the pitcher to deceive, rush, or surprise the batter by imitating a pitch while not in contact with the rubber. It is also illegal for a pitcher to “quick pitch” the batter by quickly stepping on the rubber and pitching without taking a sign. 


If the pitcher delivers a ball to the plate while in contact with the rubber, it is a pitch. If the pitcher delivers a ball to the catcher while not in contact with the rubber it is a throw. 


If there is an illegal pitch with no runner and the batter acquires first, the illegal pitch is disregarded. Otherwise, it is a ball. An illegal pitch is a balk with runners on base.
