Synopsis for the TV Cartoon Batter Up!

Marty goes back to the 1897 National League Pennant Race to help his ancestor, Pee Wee McFly- the pitcher for the Boston Beaneaters, win the Series. Using one of Doc's inventions, a pair of glasses that helps the batter to hit like a major leaguer, Marty "steps" in for Pee Wee and wins a critical game. Instead of being thankful, Pee Wee is terrified- he is being pressured to "throw" the games by Diamond Jim Tannen, a big time gangster. With Jules and Verne, Marty helps Pee Wee win the Pennant and Diamond Jim gets hauled off by the police.
