This Day in Golf History: June 15

With the drama that few can match, Jack Nicklaus won his fourth U.S. Open on this date in 1980, holding off Japan’s Isao Aoki at Baltusrol in Springfield, New Jersey. Nicklaus shot 63 in the first round then had to stay sharp the rest of the way with Aoki right on his heels all the way to the end, finishing second by two shots.
