He had barely lost, losing by a mere 58 points in the decathlon to his best friend, Rafer Johnson, at the 1960 Rome Olympic Games. Using the 2nd place finish as motivation, C. K. Yang went on to break the world record in April, 1963, and was viewed as the heavy favorite for gold at the 1964 Summer Games in Tokyo.

But it was not to be. Not only did Yang fail to win gold, he fell to a disappointing fifth place. In fact, Yang was in ninth place at the end of day one, but had a very strong day two in which he won the 400-meter hurdles, pole vault and javelin throw events, clawing his way to fourth place before the final event. But Yang’s 13th-place finish in the final 1500-meter race meant that two Germans, a Russian and an American would finish ahead of him in the final placements.

A chance at a first-ever gold medal for Taiwan faded into that cool evening of October 20, 1964. Two explanations have been provided for Yang’s disappointing results: a recent change in the way scores were tallied for the decathlon, and Yang’s mysterious illness.

The decathlon scoring system was always considered complicated, as administrators have time after time adjusted the benchmarks and formulas to come up with scores that were perceived as fair so that athletes were satisfied with their points for a strong jump, or a speedy run, as well as with their points for a fantastic jump or a spectacular run. In 1964, the scoring tables were revised yet again. And the rule changes appeared to be heir apparent, Yang, at a disadvantage. Technology advancements in plastics resulted in the increasing prevalence of fiber-glass poles. Yang had mastered the new pole more quickly than others, enabling him to claim a world indoor record in the pole vault. As legendary New York Times sports writer, Arthur Daley, explained in a preview to the 1964 Olympic decathlon, the scoring revision hurt Yang.

“Not too long ago the International Amateur Athletic Federation updated and revised the decathlon scoring tables. This has hit Yang harder than most because he no longer can make a blockbuster score of fifteen hundred points in the pole vault. He still will be the decathlon favorite but not by the preponderant margin that once had been assigned to him. “

Daley went on to quote Yang that he wasn’t overly worried. “Of course I lose points by the new tables,” he said. “But I don’t think it will affect me over the whole thing.” Others, though, believed that Yang was indeed psychologically affected by the rule changes, particularly regarding the pole vault.

Based on the revised scoring system, Yang’s world record of 9,121 points would convert to 8,087 points, which is significantly higher than gold medalist Willi Holdorf’s winning point total of 7,887. But clearly, at the 1964 Tokyo Olympics, Yang did not come close to his world-record times and distances of his 1963 world-record setting effort. The explanation at the time was that Yang was not 100% healthy. As his coach Ducky Drake said, Yang hurt his left knee about five weeks ago. He never got into shape and this was reflected in his performances.” Another report said that Yang was suffering from a cold.

But Yang’s buddy, Rafer Johnson, revealed in his book, The Best That I Can Be, a shocking explanation for Yang’s unexpected performance in 1964. Remember, this is the time of the Cold War, the Berlin Wall, Mao’s China and Chiang Kai-shek’s Taiwan.

In the 1970s, C. K. had dinner with a man from Taiwan’s counterpart to our FBI. They were talking about the 1964 Olympics when the man dropped a bombshell: C. K. had been poisoned, he said. Because of the tension with mainland China, Taiwan had assigned two bodyguard to C.K. at the Games. Despite that precaution, this man told him, a teammate had spiked C. K.’s orange juice at one of their meals. Shortly afterward, that athlete and two Taiwanese journalists defected to Red China. C. K. had always considered himself unlucky for having gotten ill at the wrong time. Instead, he may have been a victim of political warfare. “I was so angry I thought I would cry,” he told me.

Woah.
