Wrong calls are bad enough. But they’re even worse when there’s no ref to blame. Argentine Roberto De Vicenzo’s final-round score of 65 at the 1968 Masters Golf Tournament should have led him to a playoff for the championship. But when he traded the club for the pen, he lost his chance. His playing partner had recorded the wrong score for one hole — marking a par instead of a birdie — and De Vicenzo signed the scorecard, meaning that number (off by one stroke) counted. “What a stupid I am to be wrong here,” he said. And it was his birthday too.
