Rules
– The batter(s) asks for a single, double, triple, or home run question. – If the team answers correctly, the appropriate selection is made on the
baseball diamond. Other runners advance the same number of bases. – If the question if answered incorrectly, a "flyball" is called, and the
question goes to a player of the team(s) that is "in the field." – After "flyball" is called, there will be pause before a player in the field is
called to answer the question. – If the player in the field answers the question correctly, the flyball has
been caught and the batter is out. One run is subtracted from the batting team's score for each out!
– If the outfielder misses the question, the flyball has been dropped and the batter goes to first base on an error. All runners advance one base on an error.
– Questions alternate between teams after each hit or out.
