Abstract
In a golf ball for professional golfers and skilled amateurs which has a single-layer core, a cover and at least one intermediate layer therebetween, the core is molded from a rubber composition that includes a base rubber, an unsaturated carboxylic acid and/or metal salt thereof, an organic peroxide and, in a specific weight ratio, water and sulfur, and has a hardness profile which satisfies certain specific conditions. The ball achieves an excellent distance on full shots with a driver (W #1) and a middle iron, and is designed for high controllability in the short game.
