April 14, 1968: Roberto De Vicenzo signs away chance to win the Masters

Argentina's Roberto De Vicenzo is in the World Golf Hall of Fame. He won more than 200 tournaments worldwide and finished in the top five in a whopping 490 of them in his career. He was the winner of the 1967 British Open, the Senior PGA Championship in 1974 and captured the first-ever U.S. Senior Open in 1980 at age 57.

However, De Vicenzo will unfortunately always be remembered for what happened 52 years ago today in the final round of the 1968 Masters. Back then, the playoff format was 18 holes and it appeared as if De Vicenzo and Bob Goalby would meet in that on Monday.

However, De Vicenzo returned an incorrect scorecard showing a par 4 on the 17th hole instead of a birdie 3. Playing partner Tommy Aaron incorrectly marked the 4 and De Vicenzo didn't catch the mistake before signing the card. USGA rules stated the higher written score had to count. So Goalby won by a shot.

When De Vicenzo realized what he had done, he had uttered the immortal line: "What a stupid I am."

Just an utter shame as De Vicenzo had played brilliant that Sunday by firing a final-round 65 (which became a 66) on his 45th birthday. De Vicenzo never would win the Masters. He died in 2017 at age 94. That British Open would be his lone major title. His other national open titles came in his native Argentina, Belgium, Brazil, Chile, Colombia, France, Germany, Holland, Jamaica, Mexico, Panama, Peru, Spain, Uruguay and Venezuela.

The delayed 2020 Masters is scheduled to begin Nov. 12 with Rory McIlroy as the William Hill sportsbook betting favorite to win his first green jacket.
