Sec. 4. THE HOME PLATE shall be made of rubber or other suitable materials. It shall
be a five-sided figure, 17 inches across the front edge of the plate facing the pitcher. The two
sides shall be perpendicular to the front edge and shall be 8-1/2 inches long, extending forward
toward the pitcher’s plate. The sides of the plate, from the rear corner, along with the base
line, shall be 12 inches long and set completely within the base lines, where they form a 90
degree angle with the point pointing toward the catcher. The home plate is always a part of fair
territory. The black border that outlines the plate is NOT to be considered home plate.
