ABSTRACT:
A multi-piece solid golf ball comprising a core including an inner sphere and a surrounding layer and a cover enclosing the core and consisting of inner and outer cover layers is provided. The inner sphere has a hardness A expressed by a distortion of 3.5-10.0 mm under a load of 100 kg which is lowest among the ball layers. The outer cover layer has a hardness of at least 58 degrees on Shore D which is highest among the ball layers. Provided that the ball has a hardness B expressed by a distortion under a load of 100 kg, the ratio A/B is between 1.1/1 and 4.0/1. The ball has adequate spin receptivity, good flying performance, durability and a pleasant feel. Less dependence on head speed allows the ball to offer a satisfactory carry to low head speed players.
