Batter Up Description: For years, Marty has heard stories about how his ancestor – pitcher Pee Wee McFly – won the Boston Beaneaters the 1897 National League Pennant. Jules and Verne join Marty when he decides to see Pee Wee's victories for himself. When Pee Wee doesn't live up to his expectations, Marty takes his place. A pair of glasses souped up by Doc more than evens the odds for Marty. Pee Wee, however, has a reason for playing so badly – gangster Diamond Jim Tannen wanted the Boston Beaneaters to lose. Can Marty, Jules and Verne guarantee a Beaneater victory and foil Diamond Jim Tannen?
