NFHS Approves Seven Baseball Rule Changes, Including Larger First Base Option

Schools will have the option of using an 18-inch first base while coaches will also be permitted to communicate electronically with pitchers and catchers.

High school baseball teams across the country will play under seven new rules beginning in 2027 after the National Federation of State High School Associations approved a series of changes designed to improve player safety, modernize communication and streamline game administration.

Safer First Base Option Approved

Among the rule changes was the option to use an 18-inch first base or the double first base. The NFHS announced that the larger base can be used as an alternative to the previously mandated double first base, which goes into effect in 2027.

“The NFHS Baseball Rules Committee believes that providing schools with the option of using either an 18-inch first base or a double first base gives administrators the flexibility to enhance player safety while recognizing the varying needs and resources of member schools,” said Elliot Hopkins, director of sports and liaison to the NFHS Baseball Rules Committee. “Both options are designed to reduce the potential for collisions at first base and support a reduced risk playing environment without changing the fundamental nature of the game.”

The NFHS Baseball Rules Committee recommended seven rule changes during a meeting held in June, with the NFHS Rules Review Committee and NFHS Board of Directors approving all seven.

Electronic Pitch Calling Gets Green Light

Another significant change allows one-way electronic communication between coaches and either the pitcher or catcher for the sole purpose of calling pitches.

Before this change, the catcher was the only defensive player that was allowed to receive communication from the coach. 

Additional Rule Changes Coming in 2027

Additional rule changes include:

• Eye shade regulations
• Coaches being allowed to use a handheld electronic scoring devices in the coach’s box
• Expanded tiebeaker options that allow extra innings to begin with a runner on second base
• Additional approved BBCOR drop-weight bat options for younger players

“In addition, the NFHS remains committed to fostering the growth and development of high school baseball players,” Hopkins said. “As the game continues to evolve with the adoption of the USA Baseball BBCOR standard, expanding the available drop-weight options provides younger and developing players with additional opportunities to build proper mechanics, confidence and skills while maintaining the safety and performance standards expected in education-based athletics.”

Baseball Continues to Thrive Nationwide

Baseball remains one of the nation's most popular high school sports. According to the NFHS High School Athletics Participation Survey, more than 470,000 boys participated at more than 16,000 schools during the 2024-25 school year. More than 1,300 girls also competed in high school baseball.
