ABSTRACT:
A ball batting aid consisting of a spherical ball made of an expandable elastomeric material having a finite length of braided rope secured thereto, the ball being formed so that there is no air pocket within the confines thereof. An enlargement is placed on one end of the rope located in the central portion of the ball and when the ball is formed, the elastomeric material is expanded into the space between the braids of the rope to effect a securement of the material to the rope.
