Daryl,

If you throw a stick using a swing like motion, the part of the stick that has the largest swing radius will start off with greater speed than the part you were holding in your hand. As a consequence the stick will rotate in the air like a rod on a spinning wheel as it flies through the air. Do you agree?

Same thing will happen with the golf ball. The side of the ball that is furthest away from the swing center (hinge axis) will aquire more speed than the part that is acellerated with the shortest swing radius. Because it is under the laws of Centrifugal Force during impact as per your quote.
