Major 2027 High School Baseball and Softball Rule Changes Officials Need to Know

High school baseball and softball will look a little different in 2027. The National Federation of State High School Associations (NFHS) has approved several rule changes involving electronic communication, first-base safety, umpire uniforms, courtesy runners and other areas of game administration.

For umpires, these changes mean more than simply memorizing new language. Officials must understand how the rules affect pregame inspections, communication with coaches and decisions made during live play.

Electronic Communication Expands to Pitchers

One of the most notable changes affects communication between coaches and defensive players.

Beginning with the 2027 season, baseball and softball coaches may use one-way electronic devices to communicate with the pitcher and catcher while their team is on defense. Previously, high school rules were more restrictive about which players could receive electronic communication.

The coach must remain in the dugout or bench area when using the device. Communication is intended for calling pitches and sharing defensive information.

The rule does not open the door to unrestricted technology. Players may not use devices to communicate back to the coach, and athletes on the field may not wear cameras, microphones or other equipment to record, livestream or transmit audio or video. Medical devices are not considered prohibited wearable technology.

For umpires, the challenge will be distinguishing between an approved one-way communication device and equipment being used for an unauthorized purpose. Addressing questions during the pregame conference may prevent confusion once the game begins.

Baseball Requires a Safer First-Base Option

Beginning January 1, 2027, high school baseball fields must use either a double first base or a larger 18-inch square first base.

A double first base includes a white section in fair territory and a contrasting-colored section in foul territory. The alternative is a single white base measuring 18 inches square instead of the traditional 15 inches.

The purpose of the change is to reduce collisions between runners and fielders. Larger bases have already been used at other levels of baseball, while double first bases have a long history in softball.

Umpires should become familiar with the applicable rules and responsibilities associated with the type of base being used. Pregame field inspections will be especially important during the transition. Officials should confirm that the proper base is installed securely and understand any state or local interpretations governing its use.

Baseball Adds an Extra-Inning Tiebreaker Option

NFHS rules will now provide state associations with the option of using a runner-on-second-base tiebreaker procedure.

When the procedure is used, each offensive team begins its half-inning with the player scheduled to bat immediately before the leadoff hitter placed at second base. A legal substitute may enter for that runner.

This does not necessarily mean every high school baseball game will use the tiebreaker. State associations determine whether the procedure will be adopted and when it applies.

Umpires should confirm the local tiebreaker policy before the season and discuss tournament-specific procedures during the pregame meeting when necessary.

Baseball Eye Shade Must Remain Simple

Baseball players using eye black, grease or no-glare strips must wear it as a single solid stroke. Words, numbers, logos and other symbols within the eye shade will not be permitted.

The eye shade may not extend beyond the width of the eye socket or below the cheekbone.

This change creates a consistent standard and removes some of the judgment that officials previously faced when deciding whether a design was appropriate. Umpires should include eye shade in their normal equipment and uniform inspections.

Handheld Scoring Devices Permitted in the Coach’s Box

Baseball coaches will be allowed to use handheld electronic scoring devices or other approved scoring materials while occupying the coach’s box.

Permission to use a scoring device does not authorize a coach to record, stream or communicate with players in ways prohibited elsewhere in the rules. Umpires should focus on how the device is being used instead of assuming that every electronic device in the coach’s box is illegal.

Softball Clarifies Deflected-Ball Interference

The 2027 softball rules clarify how interference should be judged after a fair batted ball touches a defensive player, including the pitcher.

Once the ball touches a fielder, it is considered deflected rather than untouched when determining interference and subsequent playing responsibilities. The clarification is intended to produce more consistent rulings when a batted ball changes direction before contacting a runner or another player.

This is an important study area for softball umpires because interference plays often happen quickly and can significantly affect the game.

Softball Simplifies the Courtesy-Runner Rule

The NFHS removed language that created confusion about whether the pitcher and catcher listed on the starting lineup card were required to face the first batter while on defense.

Under the revised rule, the listed pitcher and catcher do not have to face the first batter for courtesy-runner purposes. The change eliminates a unique situation involving the transition into the bottom of the first inning and should make the rule easier for umpires, coaches and scorekeepers to administer.

States Receive More Flexibility Over Softball Umpire Uniforms

Another significant change allows state associations to establish the umpire uniform standards that best meet the needs of their officiating programs.

This does not mean individual umpires may select any uniform they prefer. Officials must continue following the requirements established by their state association, local chapter, conference or assigning organization.

Before purchasing uniforms for the 2027 season, softball umpires should confirm the approved shirt colors, pants, hats, jackets and required patches in their area. Officials working in multiple associations may need more than one approved uniform combination.

What Officials Should Do Before the 2027 Season

The new rules reflect three major trends in high school baseball and softball: increased use of technology, greater attention to player safety and an effort to simplify difficult rules.

Officials can prepare by:

• Reviewing the complete 2027 NFHS rules and points of emphasis.

• Attending their local association’s preseason rules meeting.

• Learning how approved one-way communication devices operate.

• Studying first-base responsibilities under the new baseball requirements.

• Reviewing softball interference and courtesy-runner situations.

• Confirming state and local umpire uniform standards.

• Discussing unusual procedures during the pregame conference.

Umpires should remember that state associations may adopt additional policies or restrictions. Always follow the official NFHS rulebook together with the instructions provided by your state, conference and local association.

Be Ready When the New Season Arrives

Rule changes are part of the continued evolution of baseball and softball. Technology may change how coaches communicate, and equipment may change how the field looks, but the responsibilities of an official remain the same: know the rules, communicate clearly, use sound judgment and keep the game moving.
