THE STORY
In the final round of the 1968 Masters, Roberto De Vicenzo made a birdie 3 on the 17th hole, but his playing partner, Tommy Aaron, incorrectly recorded a par 4 on his scorecard. De Vicenzo signed the card with the error, and under golf rules, the higher score counted. This mistake changed his score to 66, costing him a playoff opportunity, and Bob Goalby won the tournament by one stroke.
WHY IT MATTERS
This incident is one of the most notable in golf history, highlighting the importance of accuracy in scorekeeping and the consequences of overlooking scorecard details.
