I don't believe that someone actually needs this but here it is.

OBR 3.03
A player, or players, may be substituted during a game at any time the ball is dead. A substitute player shall bat in the replaced player's position in the team's batting order. A player once removed from a game shall not re enter that game. If a substitute enters the game in place of a player manager, the manager may thereafter go to the coaching lines at his discretion. When two or more substitute players of the defensive team enter the game at the same time, the manager shall, immediately before they take their positions as fielders, designate to the umpire in chief such players' positions in the team's batting order and the umpire in chief shall so notify the official scorer. If this information is not immediately given to the umpire in chief, he shall have authority to designate the substitutes' places in the batting order. A pitcher may change to another position only once during the same inning; e.g. the pitcher will not be allowed to assume a position other than a pitcher more than once in the same inning. Any player other than a pitcher substituted for an injured player shall be allowed five warm up throws. (See Rule 8.03 for pitchers.)
