as well as the layout of the pitch. Each team is limited to 4 players. The trap is 6 inches by 6 inches, and it has a yellow background with a black "X" mark across the front. The posts are 1–2 feet high. There are two additional lines, one of which extends across the field at a right angle 10 yards in front of the trap; this line is the "foul line". Balls put into play must not touch the ground prior to hitting this line or the batter is called out. In addition, there is an additional line 5 yards behind the posts; this line is known as the "back line", and fair hit balls that cross the line, either before touching a fielder or after, or on the ground or in the air but below the imaginary line demarcating the fair zone, score 4 runs for the batting side. This is known as a "four", and the fielding team does not have the opportunity to roll out the batter following a four. Since the posts are only 1–2 feet, the top of the fair hit zone is demarcated by an imaginary line running from the top of the tallest fielding player's head. Batted balls that travel above this imaginary line are automatically out.
