How do I keep track of mandatory play?

Question

Accepted Answer

Every rostered player present at the start of the game must play six defensive outs and bat at least once. Little League defines them as:

Six defensive outs: the player enters the field in one of the nine defensive positions and stays in that position while six outs are made. They don't need to be consecutive.
Bat at least once: the player enters the batter's box with no count and completes the at-bat by being retired, reaching base safely, being retired on the bases, scoring, or the half-inning ending.

Practical tips:

Mark the out count in the margin when each substitute enters the field, so you can tell the manager who still needs outs.
A substitute entering for the first time can't be removed before completing mandatory play, and a starter can only re-enter after their substitute has met it.
A player who misses mandatory play must start the next game, so note it in the book.
