The present invention is directed to a golf ball comprising a soft core and a hard cover such that the golf ball, when struck such as in play, exhibits a reduced spin rate. The cover may include a single cover layer or multiple cover layers. In a particularly preferred aspect, the golf ball comprises a mantle or inner layer that defines a hollow interior. The hollow mantle along with one or more resilient outer core layers constitutes the soft core. The golf ball of the present invention may also utilize an enlarged diameter which serves to further reduce spin rate. The resulting golf ball exhibits properties of reduced spin without sacrificing durability, playability and resilience.
