The bowling ball on the driveway has more thermal energy. It has been absorbing the radiant energy from the sun during those four hours. It is gaining temperature because of getting heated up, In fact, it will burn your hands when you picked it up. But the ball in second case it has kinetic energy which is different. At the bowling alley, the ball does gain a slight amount of heat from rolling, but it is not hot enough to hurt your hands.
