I, for some reason, still have the SI story you\'re referring to. Dated 11/6/78. A race-fixer named Tony Ciulla claimed to have bribed several top jockeys in the Northeast to hold horses in the trifecta races. He named Cordero, Velasquez, Baeza, Vasquez, among others. At the time of the article, the case was under investigation by authorities, so I don\'t know the outcome.
