The two tall trees circled in left field are a double if they roll in or fly in past the tree line. Any hit to the right of the 2 tall trees is a live ball except if small trees get in the way of play.
Place a cone in left centre field along the shallow ditch that follows the right field fence line of the opposite field. If a ball flies past that line to the left of the cone it’s a double. If it rolls past its a live ball unless it’s buried in long grass.
Trees circled in red on the left field line are a dead ball if hit.
Any hit that flies into the gardens in left field is a double, anything to the right is a live ball except if a goal post is in the way, then it’s a double.
