 DATE: When Bagger is instructing Junah about "The Field", (Second  Round, first day) he hands him a ball on a red tee. The tee is a  plastic one. (Note the shape of the tee having a notch for fingers,  rather than a single surface tee). At that era the tees were all  wood. Plastic tees were not introduced to the game until the 1990s  and did not become official for tournament play until late that  decade.
