ABSTRACT:
A batting practice baseball has a circumference and a diameter in the range of from approximately 65% to approximately 90% of the circumference and diameter of a regular or official league baseball sanctioned for use in league games by Rule 1.09 of the Official Baseball Rules. Preferably, the circumference of the batting practice baseball is in the range of from 5.85 inches to 8.33 inches, and the outer diameter is in the range of from 1.86 inches to 2.65 inches. The weight of the batting practice baseball is the same as the weight of an official baseball; and the resilience of the batting practice baseball should be the same as or equivalent to the resilience of an official baseball. This is achieved by constructing the batting practice baseball with materials and with yarn tension sufficient to provide a coefficient of restitution in the range of from approximately 51.4% to approximately 57.8%. Use of the comparatively smaller batting practice baseball during batting practice should improve the batting skills of a player and make the task of hitting the comparatively larger official baseball in a game situation much easier.
