Jack Nicklaus completes the first two legs of the modern Grand Slam winning the Masters and the U.S. Open (at Pebble Beach), but like Arnold Palmer in 1960, falters in the British Open by finishing second (to Lee Trevino). Nicklaus was also the holder of the 1971 PGA Championship, and so would have become the first golfer to hold all four titles at the same time, although not the first to win four consecutive professional majors. Trevino's one-shot victory at Muirfield comes after he holes seemingly impossible chip shots from off the green at both the 16th and 18th holes in the third round, and then again at the 17th in the final round - snatching the tournament from under the nose of playing partner and home favourite Tony Jacklin, who is so stunned he proceeds to three-putt the 17th from then bogey the last as well, to miss out on even second place. The young Jacklin would never again challenge seriously in a major championship.
