7.02.D Approved Team Line-ups:
7.02.D.1 Teams may bat a nine (9) player line-up, ten (10) player line-up using an Extra Hitter (EH) or continuous line-up of all present, eligible, uniformed players. Such line-up must be declared before the start of the game and used the entire game.
7.02.D.1(a) If a team uses a line-up that contains substitute players, all starting players may be removed and re-enter the game once, but must re-enter in their original position in the batting order. Non-starters are not allowed to re-enter. When a starter re-enters, the player in the starter’s batting position in the batting order must be removed from the game and is ineligible for the remainder of the game.
7.02.D.1(b) If a team uses a line-up that contains ten (10) players, the player in the Extra Hitter position, while not actually playing a defensive position, will be treated as such for substitution purposes.
7.02.D.1(c) If a team uses a continuous line-up, all players other than the nine (9) defensive position players are Extra Hitters and may move freely in defensive positions with the exception of the pitching position. Any player(s) arriving after the game has begun, shall be added to the bottom of the batting line-up. When using the continuous lineup and a player has to leave the game for any reason, that position in the line-up becomes an out when that at bat comes around.
