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. Bill Nye Segment: None, however the science segment at the end of the episode featured Brett Butler, a center fielder for the Los Angeles Dodgers at the time, talking about how curve balls curve using the Magnus effect. This is the only science segment in the show that didn't feature Bill Nye.
