The National Beep Baseball Association is playing its 36th annual World Series this week at the Mary and John Geisse Soccer Complex in Eagle Creek Park in Indianapolis. The 17 participating teams from the United States and Taiwan are made up of blind and visually impaired players. Beep baseball uses a ball that makes a beeping noise so it can be heard by players. To keep the game fair, every player wears a blindfold. The championship game will be played Aug. 6.
