Infielder

An infielder is a baseball player stationed at one of four defensive "infield" positions on the baseball field.

Standard arrangement of positions

In a game of baseball, two teams of nine players take turns playing offensive and defensive roles. Although there are many rules to baseball, in general the team playing offense tries to score runs by batting balls into the field that enable runners to make a complete circuit of the four bases. The team playing in the field tries to prevent runs by catching the ball before it hits the ground, by tagging runners with the ball while they are not touching a base, or by throwing the ball to first base before the batter who hit the ball can run from home plate to first base.

There are nine defensive positions on a baseball field. The part of the baseball field closest to the batter (shown in the diagram as light brown) is known as the "infield" (as opposed to the "outfield", the part of the field furthest from the batter, shown in the diagram as green.)
