Honorable Mention: John Fogerty
OK, so the Creedence Clearwater Revival frontman was never scouted by a major league team. Instead, Fogerty is the man responsible for the single greatest baseball song of all time. His 1985 hit "Centerfield" has become a staple in ballparks everywhere and perfectly captures the spirit of the game – so much so that, in 2010, it earned Fogerty the distinction of being the only musician ever honored by the Baseball Hall of Fame. Beat that, "Take Me Out to the Ball Game."
