1. A golf ball comprising:
a center core comprising a polybutadiene material and a methyl methacrylate, butadiene, styrene (MBS) with a weight percentage of MBS ranging from 0.5 to 5 weight percent of the center core;
an inner mantle layer disposed over the outer core, the inner mantle layer having a thickness ranging from 0.030 inch to 0.090 inch, the inner mantle layer material having a plaque Shore D hardness ranging from 30 to 50;
an outer mantle layer disposed over the inner mantle layer, the outer mantle layer having a thickness ranging from 0.025 inch to 0.070 inch; and
a cover layer disposed over the outer mantle layer;
wherein the cover layer has a thickness ranging from 0.025 inch to 0.050 inch, wherein the cover layer has a Shore D hardness less than the hardness of the outer mantle layer, and the outer mantle layer has a higher Shore D hardness than the inner mantle layer.
