A baseball game is played by two teams who alternate between offense and defense. There are nine players on each side. The goal is to score more runs than the opponent, which is achieved by one circuit of four bases that are placed on the diamond.
The defense wears baseball/softball gloves, a leather contraption that fits on the hand, to catch the ball. A baseball is a white ball roughly three inches in diameter with red stitching.
The bases are 90 feet apart on the diamond, closer in children's leagues and softball. Other fields are variable, and the outfield fences or the amount of “foul territory” - the amount of ground that borders the field between the long white lines that connect first base to home plate and third base to home plate – varies from field to field.
