Fundamentals of Baseball

By Ripken Baseball, 12/31/99, 12:00PM CST


Before your child steps onto the diamond, it’s helpful to understand the basics of the game and what to expect.

Age Group

The size of the field, length of the game, and sometimes even the number of players on the field are all determined by age group. Age groups are written as the age followed by the letter “u” to indicate that all players in that group are that age or younger. Most leagues will provide materials like charts to help determine which age group a player falls into based on their birth date.


Most teams consist of between 12–15 players, and the age groups can range from 7u to 18u depending on the league.


If a player touches 1st base, 2nd base, 3rd base, and home plate in that order, without being caught or tagged by the ball by the other team, it’s called a run. The team with the most runs at the end of the game wins.
