Abstract
In an energy absorbing base for a baseball field, a molded rubber base includes a hollow underside. Ribs arranged in a chevron-like pattern are positioned within this hollow underside, to absorb the impact energy of a player sliding into the base. The ribs are configured so that the edges of the flexing base deflect downwardly as the impact energy is absorbed. The energy absorbing capacity of the base is a function of both the material of which it is made and the dimensions of the ribs.
