Few plays in baseball are as consistently close and exciting as the stolen base.1 While there are several studies of sprinting,2–4 the art of base stealing is much more nuanced. This article describes the motion of the base-stealing runner using a very basic kinematic model. The model will be compared to some data from a Major League game. The predictions of the model show consistency with the skills needed for effective base stealing.
