Over the years, a number of sources accepted Casey's claim. As early as 1900, after Casey was "scalped" in a streetcar accident, a newspaper account noted that there was "no end" to the persons claiming to be "Casey", but cited Dan Casey as the one true "Casey" who had been immortalized by Thayer. In July 1915, a local Binghamton baseball club, the Bingos, sponsored a "Casey Day" that included a parade honoring Dan Casey as the famed "Casey." In March 1938, Casey appeared on Gabriel Heatter's radio program, broadcast on the Columbia network, to make his claim to being the famous "Casey." During the broadcast, Casey stated: I've been waiting 50 years to tell you folks that Mighty Casey was just old Dan Casey, a pretty good ball player, but no home run king. But I guess if I hadn't struck out that day I never would have become famous.
