The Field of Play
A baseball game is played on a diamond-shaped field. This field is divided into two main parts: the infield and the outfield. The infield is the grassy area enclosed by four bases, arranged in a square. These bases are first base, second base, third base, and home plate.
The pitcher's mound is a raised dirt circle in the center of the infield. From here, the pitcher throws the ball to the batter at home plate. Two white lines, called foul lines, extend from home plate past first and third base all the way to the outfield fence. Any ball hit between these lines is in fair territory; anything outside them is foul.
The distance between each base is 90 feet. The positioning of these bases creates a path that players must run to score.
The Players and Their Roles
Each team has nine players on the field at a time. Their goal is to prevent the other team from scoring runs. These positions can be broken down into three main groups: the battery, the infielders, and the outfielders.
The battery consists of the pitcher and the catcher. They work together on every pitch. The infielders protect the area around the bases, and the outfielders cover the large grassy area beyond the infield.
| Position | Primary Role |
|---|---|
| Pitcher (P) | Throws the ball from the pitcher's mound to the catcher. |
| Catcher (C) | Squats behind home plate to catch the ball if the batter doesn't hit it. |
| First Baseman (1B) | Guards first base. Fields balls hit nearby. |
| Second Baseman (2B) | Covers the area between first and second base. |
| Shortstop (SS) | Covers the area between second and third base. A key defensive position. |
| Third Baseman (3B) | Guards third base. Often fields hard-hit balls. |
| Left Fielder (LF) | Covers the left side of the outfield. |
| Center Fielder (CF) | Covers the middle of the outfield. Usually the fastest outfielder. |
| Right Fielder (RF) | Covers the right side of the outfield. |
How the Game Is Played
A baseball game is structured into innings. In a professional game, there are nine innings. During each inning, both teams get a chance to bat and play defense.
The visiting team bats in the top half of the inning, and the home team bats in the bottom half. The goal of the team at bat is to score runs. A run is scored when a player legally touches all four bases, ending at home plate.
The defensive team's goal is to get three outs. Once they do, their turn on defense is over, and they get to bat. An 'out' means a player from the batting team is removed from play for that inning.
At the plate, the pitcher throws the ball toward the batter, who tries to hit it. An umpire calls each pitch a 'strike' or a 'ball'.
A strike is a pitch that the batter swings at and misses, hits into foul territory (with less than two strikes), or that passes through the strike zone without being swung at. A batter is out after three strikes.
A ball is a pitch thrown outside the strike zone that the batter doesn't swing at. If the pitcher throws four balls, the batter gets to go to first base automatically. This is called a walk.
If the batter hits the ball into fair territory, they run toward first base. They can be called out if a defensive player catches the ball in the air (a fly out) or if the defense gets the ball to a base before the runner arrives (a force out or tag out).
The game continues inning by inning. The team with the most runs after nine innings wins. If the score is tied, they play extra innings until one team is ahead at the end of an inning.
