A baseball is a bat and ball game played between two nine-player teams who take turns batting and fielding. The fundamentals of the game involve throwing the ball, hitting the ball, and catching the ball. The goal is to score more runs than your opponent. Each time a player circles the four bases on the field, they score a run. During the first half of each inning, the visiting team bats and attempts to score points, called runs, while the home team players take their respective defensive positions in the field. The defense’s goal is to get the offensive team’s players “out” in a variety of ways. After three outs are recorded, the teams switch – the offensive team moves to defense, and the defensive team moves to offense. The batting team sends one player at a time to try and hit the ball. The two competing teams play over a period of innings, which are subdivided into halves. Professional and college games are generally nine innings long.
The defense wears baseball 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 catcher on the back side of the batter is equipped with headgear, chest protector, leg guard and other accessories to get protection from a ball to get hit. On the offensive side the batting team hits a ball with a baseball bat which is a smooth wooden or metal club after it is thrown by the pitcher. By regulation a baseball bat may be no more that 2.75 inches in diameter at the thickest part and no more that 43 inches long.
The part of the field closest to the bases is called the infield, and the grassy farther reaches are called the outfield.
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.
