Mucky Flint

Mucky Flint is a player for the Crown City Kings, who had the lowest batting average in the league during the season that takes place at the same time the Arthur series does. Though never confirmed in the series, it can be assumed that his uniform number is thirteen because the stadium scoreboard says that "13" is at-bat.

In his only appearance in "Curse of the Grebes," he hits a game-winning home run in game two of the World Championship series that appears in the episode. In this game, he is batting ninth in the order.
