1. Introduction to Baseball
Baseball is played between two teams of nine players each. It is often referred to as “America’s pastime” and has a long history dating back to the 19th century.
2. Objective of the Game
The main goal in baseball is to score more runs than the opposing team. A run is scored when a player successfully advances around all four bases first, second, third, and home plate — and touches home plate safely.
3. Players and Positions
Each team has nine players on the field when defending. The primary positions are:
- Pitcher – Throws the ball to the batter
- Catcher – Catches pitches behind home plate
- First Baseman
- Second Baseman
- Shortstop
- Third Baseman
- Left Fielder
- Center Fielder
- Right Fielder
Each of these positions plays a unique role in fielding and defending against the offensive team.
4. Basic Structure of the Game
A standard professional baseball game consists of nine innings. Each inning is split into two halves:
- Top half: The visiting team bats.
- Bottom half: The home team bats.
Each team gets three outs per half-inning, and the sides switch roles afterward.
If the score is tied after nine innings, the game may go into extra innings until a winner is determined.
5. Scoring in Baseball
To score a run:
- A batter must hit the ball and become a runner.
- The runner must advance to first base, then second, third, and finally touch home plate.
- Runners can advance through hits, walks, errors, or strategic plays like steals and sacrifices.
A home run occurs when the ball is hit out of the playing field in fair territory, allowing the batter (and any runners on base) to score automatically.
6. Batting Rules
Batting is a central part of the game. The goal is to reach base or drive in runs. Here’s how it works:
The Count
- Balls: If a pitcher throws four balls outside the strike zone, the batter earns a walk.
- Strikes: Three strikes and the batter is out.
- The strike zone is the area over home plate between the batter’s knees and chest.
Hits
There are several types of hits:
- Single: Batter reaches first base
- Double: Batter reaches second base
- Triple: Batter reaches third base
- Home Run: Batter circles all bases
Outs
A batter can be out by:
- Striking out
- A fielder catching the ball before it hits the ground (fly out)
- A ground ball resulting in a force out at a base
7. Pitching Rules
The pitcher plays a critical role in the game, aiming to retire batters by throwing balls that are difficult to hit.
Legal Pitching
- The pitcher must keep one foot on the pitching rubber.
- A windup or set position must be followed for a legal pitch.
- Balks are called when a pitcher makes an illegal motion, allowing runners to advance one base.
Types of Pitches
- Fastball: High-speed straight pitch
- Curveball: Bends downward or sideways
- Slider: Sharp break to the side
- Changeup: Slow pitch thrown with fastball mechanics
8. Fielding Rules
Fielding is all about defense — catching balls, throwing accurately, and tagging runners.
Force Out
A force out occurs when a runner is forced to advance and a fielder touches the base with the ball before the runner arrives.
Tag Out
A tag out happens when a fielder tags a runner with the ball while the runner is off the base.
Double Play
A play where the defense records two outs in a single sequence, often involving quick throws between infielders.
9. Common Violations and Penalties
Understanding infractions is vital to grasping the rules.
Balk
Illegal movement by the pitcher that deceives runners. All runners move up one base.
Interference
- Offensive interference: Batter or runner impedes a fielder
- Defensive interference: Fielder obstructs a runner without possession of the ball
Obstruction
When a fielder blocks a runner’s path without the ball.
Illegal Batting
A batter stepping out of the box while hitting the ball is considered out.
10. Extra Innings and Tie-Breakers
If the game is tied after 9 innings:
- Extra innings are played until one team is ahead at the end of a full inning.
- In professional baseball (like MLB), a runner starts on second base in extra innings to speed up the game.
11. Key Baseball Terminologies
Understanding some common baseball terms will help you follow the game better:
- At-Bat (AB): A batter’s turn to hit
- On-Deck: The next batter in line
- RBI (Runs Batted In): A stat showing how many runs a player drove in
- ERA (Earned Run Average): Pitcher’s average number of earned runs allowed per 9 innings
- OPS: On-base Plus Slugging percentage — a measure of offensive performance
- Sacrifice Fly: A fly ball that allows a runner to score after the catch
- Inning-ending double play: A double play that ends the offensive team’s turn
