Substitutions in Little League All Stars

Question
Player A starts the game, and in the 3rd inning, player B comes in to substitute Player A, he plays the inning and gets his at bat. Can you then Substitute player A back in for Player B in the next inning? We were advised at our All Star Game yesterday that if you substitute a player, the player you remove, is not allowed back in for the rest of the game, I find that hard to believe, and I could not find it in the rule book. Thanks for any advise you can give.

Answer
Sarah,

A starter can reenter the game, but only in the position they occupied previously.  However, a substitute cannot reenter a game.

So, for example:

Player A starts the game.  Player B substitutes for Player A in the 3rd inning. Player B completes mandatory play and in the 5th inning, Player A reenter for Player B.  This is legal.  However, Player B is done for the game, and cannot be reentered for any other player.

I hope this has helped.
