That is, the ball is being pitched towards the batter on a particular plane (and actually changes planes depending on what type of pitch). A batter, by striding too far actually changes the plane that his or her head is on, thereby making the ball appear to move slightly. This usually results in a batter hitting the bottom of the ball because the eyes and head have moved down a plane and as a result they are no longer swinging at the part of the ball at which they were aiming.
