RULE 4 – PLAYER EQUIPMENT
SECTION 1 REQUIRED EQUIPMENT
SECTION 4 UNIFORMS
ART. 1 Uniforms of all team members should be of the same color and style. Caps and shoes are required equipment (no track spikes allowed). When a player is required to wear a head protector, it replaces the cap as mandatory equipment.
ART. 2 For individual players, uniform sleeve lengths may vary. However, sleeves of each individual player shall be approximately the same length and shall not be ragged, frayed or slit. If the pitcher’s undershirt sleeves are exposed, they shall not be white or gray. A pitcher shall not wear any item on his hands, wrists or arms which may be distracting to the batter. A pitcher shall not wear white or gray exposed undershirt sleeves or any white or gray sleeve that extends below the elbow. A vest and coordinating shirt that is worn underneath is viewed as a type of uniform top.
ART. 3 A uniform shall not have any dangerous or reflective buttons or ornaments. Each player shall be numbered on the back of his shirt with a plain number of solid color contrasting with the color of the shirt. This number shall be a plain Arabic style and shall be at least eight inches high, and no players of the same team shall wear identical numbers. A number may have a border of not more than one-quarter inch in width.
ART 4. The school’s official uniform (including uniform pants, jersey, visible undergarments, socks, stockings, caps and headwear) may bear only a visible single manufacturer’s log (partial or whole) or trademark. A manufacturer’s logo/trademark shall not exceed 2 1/4 square inches with no dimension exceeding 2 1/4 inches. No more than one manufacturer’s logo/trademark or reference shall be permitted on the outside of each item. (The same restriction shall apply to either the manufacturer’s logo/trademark or reference.) One American flag 2 inches x 3 inches may be worn on each item of uniform apparel. By state association adoption, to allow for special occasions, commemorative or memorial patches, that will be uniformly placed, not to exceed 4 square inches, to be worn on jerseys in an appropriate and dignified manner without compromising the integrity of the uniform.
