“NOTE 1: The on-deck position is not permitted in Little League (Major) Division and below.
So we interpret this as:
Players are not permitted to take practice swings in between innings and/or while the pitcher is warming up. Got a couple of presidents from other leagues saying that while players are switching sides, the player due up can come out of the dugout and swing away. Because it is their turn at bat, they are not "on-deck."
Several of our board members, mostly ones coaching teams, agree with free swings idea.
How do other league see it?
