Golf ball comprising a core layer having a hardness gradient and trans gradient

A golf ball comprising:

• an inner core having a first outer surface and a geometric center and being formed from a first substantially homogenous rubber composition such that the geometric center has a hardness of about 52 Shore C to about 58 Shore C, and the first outer surface has a trans content of about 15% to 25%, the geometric center has a trans content of about 10% to 15%, and the trans content of the outer surface is greater than the trans content of the geometric center by about 10% to 15% to define a trans gradient;
• an outer core layer disposed about the inner core and being formed from a second substantially homogenous rubber composition such that the outer core layer has a trans content of about 6% to 12%;
• and
• a cover layer disposed about the outer core layer comprising a castable polyurea or a castable polyurethane;
• wherein a hardness of the first outer surface is about 72 to 78 Shore C and is greater than a hardness of the geometric center to define a positive hardness gradient of about 1 to 20.

A golf ball comprising:

• an inner core having an outer surface and a geometric center and being formed from a first substantially homogenous rubber composition;
• an outer core layer disposed about the inner core and being formed from a second substantially homogenous rubber composition, the outer core layer having a trans gradient of about 20% to 45%;
• and
• a cover layer disposed about the outer core layer;
• wherein the outer surface has a trans content of about 6% to 10%, the geometric center has a trans content of about 1% to 3%, and the trans content of the outer surface is greater than the trans content of the geometric center by about 6% or greater to define a trans gradient.
