Chapter 1: 1. Field, Players, and Basic Structure
The Baseball Field
A baseball field is a diamond with four bases:
1. Home plate
2. First base
3. Second base
4. Third base
Key zones:
- Infield: dirt area around the bases
- Outfield: grass beyond the infield
- Foul lines: extend from home through first and third
Any ball outside the foul lines is usually foul; inside is fair.
Teams and Positions
Each team fields 9 players on defense:
- Pitcher
- Catcher
- 1B, 2B, 3B
- Shortstop
- Left, Center, Right Fielders
On offense, players bat one at a time in a set batting order.
> Once the game starts, the batting order cannot change, only cycle.
Innings and Outs
A regulation game has 9 innings.
Each inning has:
- Top: visiting team bats
- Bottom: home team bats
On offense, your half‑inning ends when the defense gets 3 outs.
Common ways to get out:
- Strikeout
- Flyout
- Groundout/force out
- Tag out
How Runs Score
A run scores when a runner legally touches:
1. First base
2. Second base
3. Third base
4. Home plate
…in order, on the same play.
Types of hits:
- Single: reach first
- Double: reach second
- Triple: reach third
- Home run: batter scores, plus any runners already on base
