Baseball Field Orientation
The orientation of a high school baseball field can help players see the baseball whirling toward them at a high rate of speed. Fans can see the entirety of the field and how the game is playing out with the right orientation.
There are official rules regarding the optimal baseball field orientation. According to Rule 1.04, the line from home base through the pitcher’s plate to the second base should run east to northeast.
There is a reason behind this rule. As the sun rose and fell, shadows moved across the field and would impede visibility for the players and spectators. Building baseball fields with an east to northeast orientation prevents issues with visibility regardless of the time of day.
