Abstract
A game projectile of unique contour adapted to be manually thrown in a plurality of trajectories. The combination of elements of the game projectile allows for minimal displacement path of the projectile subsequent to being dynamically impacted by a bat or stick member. The game projectile includes a first hemispherical contoured member which is formed of a resilient composition and is substantially symmetrical about a first vertically directed axis line. The game projectile further includes a second hemispherically contoured member having a radius less than the radius of the first hemispherically contoured member. The second hemispherically contoured member is formed in one piece formation with the first hemispherically contoured member on an external surface thereof in order to provide the pitcher with various gripping mechanisms to control the trajectory of the game projectile. In order to minimize the acceleration forces applied to the game projectile by a stick or bat member, both of the first hemispherically contoured member and the second hemispherically contoured member are formed in the hollow manner in order that great deformation may occur when dynamic impact loading occurs.
