 A player must deliver the bag from either the left or right pitcher's box, and remain in that designated pitchers box for the duration of the game in doubles or crew (in crew, each player will only throw 2 bags, however).In singles play, a player will throw from both the right and left pitcher's box during the game as the players walk down to retrieve their bags in their designated lane.At no time will opponents throw from the same pitcher's box during a frame.
