All teams must use a continuous batting order, meaning that the entire rosters of players present must be placed in the batting order. (LL Rules, 2.0, Batting Order; 4.04, Note 1, Note 2)
There is no on-deck circle allowed in Little League. Under no circumstances shall any player have a bat in hand until the player is wearing a Little League approved batting helmet, an adult is immediately present, and it is time for the player to bat. (LL Rules, 1.08, Note 1)
Only the first batter of each half-inning will be permitted outside the dugout between half-innings. (LL Rules, 1.08, Note 2)
Batboys and batgirls are not permitted. (LL Rules III(b))
Batters may not walk or strike out. To keep the pace of play moving, if a batter does not put the ball in play after approximately three or four pitches, have the batter hit the ball from a tee.
Batters may not bunt. If the batter takes a swing and puts the ball in play, the batter may advance to first base regardless of how far the ball travels.
