Baseball The Field

Baseball is played on a field or diamond. Get ready to learn all about the field, its lines, dimensions, and parts.

The Field

Let's start with the field. Often referred to as the diamond, the field has four corners that make up the infield made of sand. It extends backward into a grassy patch known as the outfield. Those four corners are known as bases: first base, second base, third base and home plate, moving counterclockwise. In the middle of the diamond, between home and second base, is where the pitching rubber lies and where play begins. Two lines extend diagonally from home plate known as foul lines, which are the boundaries in baseball.

Baseball is most often played in open stadiums or outdoor fields, making games susceptible to weather, so it makes sense that it begins in the spring and ends in the early fall. Professional baseball fields are on average a bit bigger than college and high school fields in the outfield, but almost all regulation baseball infields have bases that are 90 ft apart. Softball fields tend to be smaller as well, with 60 ft in between the bases.

You don't need to be at Fenway to play ball, all you need is four bases, a pitching area, space for an outfield, and preferably some dirt or grass to slide in safely.

The baseball field is a beautiful feat of engineering. Made of grass and dirt, the baseball field consists of the infield and the outfield. The infield known as the diamond is where the action happens. White lines, made of non-toxic white chalk, mark the running lane for the players. In professional leagues like the MLB, the infield is made of dirt that must be leveled.

The Infield And Outfield

Every baseball field consists of an infield and outfield where most of the field lines and components are. Baseball fields have two main components: the infield and the outfield. The infield is shaped like a diamond, which is why baseball fields are often called diamonds. There are four bags or bases at the corners of the diamond. In order, they are called 1st base, 2nd base, 3rd base, and home plate. The infield is made of dirt, and the outfield consists mostly of grass.

The Outfield is the area between the foul lines formed by extending the two sides of the square. The outfield is made entirely of grass and extends into the spectator seating area. Spectator seating is called the grandstand, covered with a roof wrapping entirely around home plate.

The Bases

There are four bases called 1st base, 2nd base, 3rd base, and home plate that are in the infield.

Foul Lines

The foul lines are similar to inbounds and out of bounds in other sports. If a batter hits a ball outside the foul lines before the ball passes first base, it's a foul ball. If the ball stays on or within the foul lines it is a fair ball.

Other Field Components

The on-deck circle and dugout are where the batters and other players on the team wait their turn to bat when their team is on offense. There's a mound of dirt at the center of the infield called the pitcher's mound. It is used by the pitcher to throw pitches to batters at home plate.

There are three types of boxes on the baseball field, the catcher's box, batters' boxes, and coaches' boxes. The catcher's box is where the catcher squats, located behind home plate. The batters' box is where the batter stands for the duration of his time at bat. These boxes are used for various aspects of a baseball game and are focused around hitting, base running, and coaching.

Each team has a dugout or a bench reserved for players and other members of the team. Dugouts are like bunkers, slightly underground. No one except players, substitutes, managers, coaches, trainers, and batboys can occupy a bench in the dugout during a game. If needed, the home team provides police protection to preserve order during the course of a game.
