In his later years, Casey claimed to be the Casey about whom Ernest L. Thayer wrote his famous poem, "Casey at the Bat." Casey was given a parade honoring him as the famed "Casey", was featured on a national radio broadcast, and participated in a "re-enactment" of "Casey at the Bat" when he was age 78. The poem's author denied that his work was based on any real player, and several sources have called Casey's claim into doubt. Casey had a career batting average of .162 and one home run.
