Softball is an activity descended from baseball, in which a ball, eleven to twelve inches (or rarely, 16 inches) (28 to 30.5 centimeters) in circumference, is thrown (pitched) underhand by a player called a pitcher and hit by an offensive player called a batter with a round, smooth stick called a bat (usually wooden, metal or composite). Scoring is accomplished by the batter running and touching a series of three raised markers on the ground called bases, and then touching the final base, called home plate.

In softball there is an offensive team, the team that bats , and a defensive team, the team that occupies the field. Both teams switch between offense and defense. The determining of which team is offense and which is defense is based on a series of outs. The goal for the defensive team is to receive these outs. Outs can be received in many ways. One way to get an out is by, a defensive player catching a ball, which was hit by an offensive player, in the air. Another way is by a defensive player throwing the ball to another defensive player, that is standing on a base, before the offensive player reaches that base. A third is by the pitcher striking out the batter.
