Abstract
A baseball includes a spherical core of foamable material and three layers of foamable material engaged on the spherical core and a cover layer engaged on the three layers. The intermediate layer of the three layers includes a hardness and a density greater than that of the other two layers and less than that of the spherical core, for allowing the other two layers to form a cushioning device and for preventing the players from being hurt by the baseball.
