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.
Its not daryl but...... I'm not sure I (3putt) agree.
If you throw the stick as you describe AND in doing so you(knowingly or unknowingly) apply a force that causes the stick to rotate around an axis internal to the stick, then yes, the stick will continue to rotate once it is separated from your hand.
If you throw the stick and do not introduce any forces other than the centripetal force your arm was already applying to the stick, then every atom in that stick will fly off in a straight line, tangential to the circle it was moving on. I agree there will be an imbalance (as you pointed out the part of the stick further away from the centre of the circle has greater speed) but I think the system will rebalance - some atoms will slow, others speed up,- conserving momentum for the entire system as a whole - and in short order the entire stick will move on a linear path, same as the centre of gravity, with no rotation.

But I am speculating only.

And, though interesting, is this really going to help my golf game?
