Bob Goalby won his only major championship, one stroke ahead of Roberto De Vicenzo, the reigning British Open champion.

Playing partner Tommy Aaron incorrectly marked the 4 and De Vicenzo failed to catch the mistake and signed the scorecard.

USGA rules stated that the higher written score signed by a golfer on his card must stand,[3] and the error gave Goalby the championship.

Lee Trevino, 28, made his Masters debut and was two strokes back after three rounds, tied for seventh place.
