 Leading up to the 1958 Kentucky Derby, the California horse Silky Sullivan received much publicity for his habit of coming from very far behind to win races.It was the first time television played a major role in the publicizing of a racehorse, and after Valenzuela won the Derby on board Tim Tam, the next day he was flown to New York City to make a guest appearance on CBS Television's The Ed Sullivan Show.Two weeks later, Valenzuela and Tim Tam won the Preakness Stakes, but in the final leg of the Triple Crown, they finished second at the Belmont Stakes after the horse fractured a sesamoid bone near the end of the race.
