Abstract
A game ball having a hollow core structure which is resistant to permanent denting or “oil canning” when struck with a bat. The game ball also has a higher moment of inertia due to its hollow construction and consequently has a lower spin rate making it more suitable for play in confined areas and for use by lower skilled players. The core of the ball is formed from a thermoset elastomeric material and the wall thickness of the game ball ranges from 10 to 36 mm.
