The shape
The No doubles (deep outfield) sets out 2 in battery, 4 in infield and 3 in outfield. The diagram shows where each position starts, on a 126.92 m by 150 m baseball diamond drawn to scale with your own end at the top. Use it as the starting picture for your team sheet, then adjust the depth of each line to the players you have and the opponent in front of you.
