A golfball comprising a liquid core and a reaction-injection-molded (RIM) cover material is disclosed. The liquid core comprises a core shell defining a hollow region, the hollow region containing a fluid. The reaction-injection-molded material may be a reaction-injection-molded polyurethane, a reaction-injection-molded polyurea, a reaction-injection-molded polyurethane/polyurea blend, or mixtures thereof. A golfball with a liquid core and RIM cover exhibits variable spin characteristics and a larger spin decay.
