Key Factors determining your Strike Zone


Batter's natural and usual stance

Some batters crouch when they swing. Others stand more upright.


You should observe the first swings of a batter to determine their stance and adjust your strike zone accordingly. For example, you should tighten your strike zone on a batter who crouches during his/her swing.

Age of the


The younger they are, the bigger (height and width) your strike zone should be. A generous strike zone for younger players (< 11 years old) will have them swinging often, keep the defense alert and speed up the game for everyone.

Time of season

At any age, your strike zone should be bigger at the beginning of the season and become smaller as pitchers become more proficient.

Just because ...

Whether it's a game with inexperienced pitchers, nasty weather, kids that won't swing, a bad stomach ache, or all of the above - you will find times when your strike zone is just not big enough!

(Little League Umpiring 101)

Adjust your strike zone for each game

-  Little League Rule Book states: "The strike zone is that space over home plate which is between the batter's armpits and the top of the knees when the batter assumes a natural stance. The umpire shall determine the strike zone according to the batter's usual stance when that batter swings at a pitch."

-  During the game, the consistency of your strike zone is key, especially during a batter's at-bat sequence. I've heard many a coach and parent mutter complaints about a strike zone but then finish with "... but it was consistent". Translated = great job Blue!

The Junior Umpire Program

Our Junior Umpire program comprises boys and girls aged 12 and older who have experience playing baseball, softball or umpiring, and who have a lot of self-confidence and enjoy the sport. Junior umpires, start out umpiring at the Coach Pitch  level (9 and 10 year olds), then, as skills and experience grow, they move on to umpire at the Minors and Majors levels. Junior umpires will be paired with adult umpires during games (Minors and up). If you would like more information or would like to volunteer for become an Umpire, please contact your UIC.
