Standard Alignment
The classic 9-player setup — four infielders, three outfielders, pitcher, and catcher. Every youth and rec league starts here. Players shift slightly depending on the batter, but this is the base position.

Parent's Cheat Sheet
What just happened?
Official Wording
A game consists of nine innings. Each team gets three outs per half-inning. The home team bats in the bottom half; the visiting team bats in the top half.
Parent Translation
Think of it as 18 mini-rounds. Your kid's team bats in the bottom of each inning (if home) or the top (if away). Three outs and the other team gets their turn. Youth games are often shortened to 5 or 6 innings, or played with a time limit.
