Let me through this out there as a newcomer. What is allowed during
games with player substitutions. Is there open substitutions? Can
player come out and re-enter a few innings later in a different
batting order? Is re-entering allowed? If only 12 players show for a
game, can all 12 bat in the order? Is all this determined on a game-by
game basis?

By the way, the Wheelmen had their first practice today and we had a
blast. We will be ready!
