| Babe Ruth IV|
|First Appearance||"Wild Barts Can't Be Broken"|
Babe Ruth IV is a member of the Springfield Isotopes in the episode "Wild Barts Can't Be Broken". He is the illegitimate great grandson of Babe Ruth. He is declared to be "no Babe Ruth III" and does not have any lines in the episode.
While at bat, he points towards the right field bleachers, looking at a "dying little boy" (a reference to the supposed origin of his famous "called shot" in 1932) , then points down to signal a bunt. He is immediately tagged out. Later in the episode, the Isotopes win the championship game, but it is unclear if Ruth was still a member of the team.
