Effective January 1, 2027, a double first base will be required in high school baseball games to minimize the risk of collisions by runners and fielders.
The new language notes that the double first base must be white and a contrasting solid color. The white portion of the base is located in fair territory while the colored half is located in foul territory, split by the first base foul line. There is to be no space between the two portions of the double base.
