For a short period of time beginning in the late 1950s, Latter-day Saint missionaries in certain parts of the world required youth to be baptized as a prerequisite for learning how to play baseball. Missionaries had initially used baseball as a tool to befriend the community, but overzealous mission leaders soon took the initiative in a new direction. For a time, it also received the support of general authorities like Alvin R. Dyer and Henry D. Moyle before President David O. McKay dispatched Marion D. Hanks to “clean up the mess.” In this interview, Greg Prince explains the history of baseball baptisms.
