Section 1 - POSITIONS OF PLAYERS
1-1-1 In high school baseball, each team is permitted seven turns at bat (see 4-2-2) during which it attempts to score runs by having its batters become base runners who advance to and touch first base, second base, third base and home plate. The team in the field attempts to end each turn at bat of the opponent by causing three of its batters or base runners to be out. Each of the two teams consists of at least nine players throughout the game (See Exception 4-4-1f), one of whom must be designated captain.
1-1-2 The captain and head coach represent the team in communications with umpires. The captain's and head coach’s duties shall include: 1) providing the umpire-in-chief with his team's lineup card which shall include the name, shirt number, position and batting order of each starting player, the name and shirt number of each eligible substitute should also be listed; and 2) informing all players as to special ground rules as announced by the umpire-in-chief. Lineups become official after they have been exchanged, verified and then accepted by the umpire during the pregame conference. The umpire shall not accept the lineup card until all substitutes are listed. There is no penalty assessed.
1-1-3 A player is designated on the line up card and in the scorebook by name, shirt number, batting order position and fielding position. A customary arrangement of the fielders is shown in Diagram 1.
1-1-4 At the time of the pitch, all fielders shall be on fair ground except the catcher who shall be in the catcher's box. A fielder is in fair ground when at least one foot is touching fair ground. PENALTY: Illegal pitch. (2-18)
1-1-5 A player may change to a different fielding position at any time except that a pitcher, after being listed as such on the official lineup card handed the umpire, cannot change until conditions in 3-1-1 and 3-1-2 are met. Changes should be reported to the umpire-in-chief and scorekeeper.
Section 2 - THE FIELD
1-2-1 A diamond (or infield) shall be a 90-foot square. When measuring the distance to first base and third base, measure from the apex of home plate to the back edge of the base. The outfield is the area between two foul lines formed by extending two sides of the diamond as in Diagram 2. The infield and outfield, including the boundary marks from home plate to first and third and their extended foul lines, are fair ground. All other area is foul ground.
1-2-2 All lines on the playing field shall be marked with a material which is not injurious to the eyes or skin. All non-permanent lines should be white. Lime or caustic material of any kind is prohibited.
1-2-3 The on-deck circle should be to the side and away from home plate, 37 feet if space allows. Neither team's players shall warm up in the other team's on-deck circle. The on-deck circle does not have to be occupied, but if a player wishes to warm up, he shall do so only in his team's on-deck circle, provided the on-deck circle is located safely away from home plate. (2-23)
1-2-4 When the dugout area is temporarily extended, for any reason, it shall be extended toward the outfield on a line parallel to the foul line. The extension of the dugout area shall be equally applied for both teams.
1-2-5 When constructing a new field for high school play, the distance from home plate to the nearest obstruction on fair ground should be at least 300 feet down the foul lines and at least 350 feet to center field. It is recommended that the line from home plate through the pitcher's plate to second base run east-northeast. This line, using a steel tape or a strong tape or a cord, must measure 127 feet, 3-3/8 inches from the rear tip of home plate to the middle of second base. The catcher's box, home plate, bases, coaches' boxes, batters' boxes, and three-foot running lane shall be as in Diagram 2. The recommended width of a foul line is 2-1/2inches.
1-2-6 On a sodded field, an unsodded area, commonly referred to as the "pitcher's mound," should have a radius of about nine feet centered 1-1/2 feet in front of the midpoint of the front edge of the pitcher's plate.
1-2-7 The pitcher's mound may consist in part of synthetic material that is commercially manufactured for that purpose. If a mound pad is composed of natural soil and synthetic material, the synthetic material must be securely attached to the ground and be installed at least flush or slightly below the surface of the ground. The mound area shall meet suggested height and slope specifications found in the Suggested Layout of the Pitcher's Mound (Diagram 3).
1-2-8 Media shall be prohibited from being in live-ball area. If a designated media area is to be used, it shall be established before the game begins. The home team or game management shall designate a lined area for the media, which shall be considered dead-ball area.
1-2-9 First, second and third bases shall be white bags, 15 inches square and 2 to 5 inches in thickness, and made of canvas filled with a soft material, or molded rubber or synthetic material, and shall be securely attached to the ground or an anchor system as in Diagram 2. Bases may have tapered edges and/or be designed to disengage from their anchor systems. By state association adoption, a double first base is permitted. The double first base shall be a white base and a colored base. The colored base shall be located in foul territory. (See Suggested Double First Base Rules, page 63)
1-2-10 Home plate shall be a five-sided slab of whitened rubber or other suitable similar material. One edge is 17 inches long, two are 8-1/2 inches and two are 12 inches. It shall be set in the ground so that the two 12-inch edges coincide with the diamond lines extending from home plate to first base and to third base, with the 17-inch edge facing the pitcher's plate.
1-2-11 The pitcher's plate shall be a rectangular slab of whitened rubber or suitable material, 24 inches by 6 inches. It shall be set in the ground as shown in Diagram 2 so that the distance between the nearer edge of the pitcher's plate and the rear tip of home plate shall be 60 feet, 6 inches.
1-2-12 Any game started on a no regulation facility by mutual agreement of the opposing coaches shall not be protested for this reason.
Section 3 - BATS, BALLS & GLOVES
1-3-1 The ball shall meet the current NOCSAE standard for baseballs at the time of manufacture and is required on balls that will be used in high school competition. (Effective January 1, 2020) The SEI/NOCSAE mark is required on all balls that meet the NOCSAE standard that will be used in high school competition. Please see the mark below. A minimum of three umpire-approved baseballs shall be provided to start the game. Unless otherwise mutually agreed upon, the home team has this responsibility. No less than two baseballs shall be used to complete the game.
The NFHS Authenticating Mark is required on all balls that will be used in high school competition.
A current list of NFHS authenticated products can be found on the Web site: www.nfhs.org.
1-3-2 The bat shall have the following characteristics and components.
NOTE: The NFHS has been advised that certain manufacturers consider alteration, modification and "doctoring" of their bats to be unlawful and subject to civil and, under certain circumstances, criminal action.
1-3-3 A bat made of a single piece of wood may be roughened or wound with tape not more than 18 inches from the handle end of the bat. No foreign substance may be added to the surface of the bat beyond 18 inches from the end of the handle. Each bat made of a single piece of wood shall be:
1-3-4 Only bats may be used in warming up (including weighted bats used for this purpose) at any location. Only bats and items designed to remain part of the bat, such as weighted bats, batting donuts, and wind-resistant devices are legal at any location.
1-3-5 Bats that are altered from the manufacturer’s original design and production, or that do not meet the rule specifications, are illegal (See 7-4-1a). No foreign substance may be inserted into the bat. Bats that are broken, cracked or dented or that deface the ball, i.e., tear the ball, shall be removed without penalty. A bat that continually discolors the ball may be removed from the game with no penalty at the discretion of the umpire.
1-3-6 Gloves/mitts made of leather shall be worn by all fielders and not be altered to create an adhesive, sticky, and/or tacky surface. The glove/mitt worn by the catcher may be any size. The glove/mitt worn by the pitcher that includes the colors white and/or gray shall be removed from the game upon discovery by either team and/or umpire. The glove/mitt worn by all fielders except the catcher shall conform to the following maximum specifications (found in Diagram 4):
1-3-7 Loose equipment, such as gloves, bats, helmets or catcher's gear, of either team may not be on or near the field.
PENALTY: If loose equipment interferes with play, the umpire may call an out(s), award bases or return runners, based on his judgment and the circumstances concerning the play.
Section 4 - UNIFORMS
1-4-1 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.
1-4-2 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. Compression sleeves that are solid black or solid dark-colored shall be the only colors allowed to be worn by the pitcher below his elbow. 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.
1-4-3 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 on the same team shall wear identical numbers. A number may have a border of not more than one-quarter inch in width.
1-4-4 The school's official uniform (including uniform pants, jersey, visible undergarments, socks, stockings, caps and headwear) may bear only a visible single manufacturer's logo (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.
Section 5 - PLAYER EQUIPMENT
1-5-1 It is mandatory for on-deck batters, batters, runners, retired runners, players/students in the coaches boxes as well as non-adult bat/ball shaggers to wear a batting helmet that has a non-glare (not mirror-like) surface and meets the NOCSAE standard at the time of manufacture. The batting helmet shall have extended ear flaps that cover both ears and temples and also display the NOCSAE stamp and the exterior warning statement. The warning statement may be affixed to the helmet in sticker form, or it may be embossed at the time of manufacture. A violation by a no adult bat/ball shagger shall result in a warning to the coach of the team and the individual. A subsequent violation may result in the individual not being allowed on the field.
PENALTY: When an umpire observes anyone who is required to wear a batting helmet deliberately remove his batting helmet while in live-ball territory and the ball is live (non-adult ball/bat shaggers required to wear batting helmet in live-ball area even if ball is dead), the umpire shall issue a warning to the coach of the involved team, unless the ball becomes dead without being touched by a fielder or, after being touched, goes directly to dead-ball area. A subsequent violation of the rule shall result in ejection.
1-5-2 A face mask/guard may be attached to batting helmets at the time of manufacture. All face mask/guards shall meet the NOCSAE standard. A face mask/guard specifically designed for a particular helmet model may be attached after manufacture, provided that procedure is approved by the manufacturer and meets the NOCSAE standard.
1-5-3 The catcher shall wear, in addition to a head protector, a mask with a throat protector, body/chest protector that meets the NOCSAE standard at the time of manufacture (Effective January 1, 2020), protective cup (male only), and baseball protective shin guards.
1-5-4 The catcher's helmet and mask combination shall meet the NOCSAE standard. Any helmet or helmet and mask combination shall have full ear protection (dual ear flaps). A throat protector, which is either a part of or attached to the catcher's mask, is mandatory. A throat protector shall adequately cover the throat. The commercially manufactured catcher's head, face and throat protection may be a one-piece or multi-piece design. While in a crouch position, any non-adult warming up a pitcher at any location shall wear a head protector, a mask with a throat protector and a protective cup (male only).
PENALTY: Failure by a player to wear proper equipment after being so ordered by the umpire, shall result in ejection.
1-5-5 Defensive players are permitted to wear face/head protection in the field. If a pitcher or any defensive player wears face/head protection, its outer covering shall have a non-glare (not mirror-like) surface.
1-5-6 Defective equipment must be repaired or replaced immediately.
1-5-7 If a ball is touched with an illegal glove or mitt, that is discovered by the umpire, the coach or captain of the team at bat has the choice of taking the result of the play or having the award (8-3-3a, b, c) for use of an illegal glove or mitt. The illegal glove or mitt must be replaced immediately. A foul fly caught with an illegal glove/mitt shall be nullified and treated as a foul ball, unless the team at bat elects to take the result of the play.
1-5-8 Hard and unyielding items (guards, casts, braces, splints, etc.) must be padded with a closed-cell, slow-recovery foam padding no less than 1/2" thick. Knee and ankle braces which are unaltered from the manufacturer's original design/production do not require any additional padding. Each state association may, in keeping with applicable laws, authorize exceptions to NFHS playing rules to provide reasonable accommodations to individual participants with disabilities and/or special needs, as well as those individuals with unique and extenuating circumstances. The accommodations should not fundamentally alter the sport, allow an otherwise illegal piece of equipment, create risk to the athlete/others or place opponents at a disadvantage.
1-5-9 Any player equipment judged by the umpire to be unreasonably dangerous is illegal.
1-5-10 Any questions regarding legality of a player's equipment shall be resolved by the umpire-in-chief.
1-5-11 Non-traditional playing equipment must be reviewed by the NFHS Baseball Rules Committee before it will be permitted to be used.
1-5-12 Jewelry shall not be worn (See 3-3-1d) except for religious or medical medals. A religious medal must be taped and worn under the uniform. A medical alert must be taped and may be visible.
