NFHS 1-1-4

NFHS 1-1-4/OBR 4.03

All fielders must be in fair territory when the ball is pitched, with the exception of the catcher, who must be in the catcher’s box. A fielder is considered to be in fair territory if at least one foot is touching fair territory. If there is a violation, the pitch is ruled to be illegal.

[OBR requires both feet in fair territory except catcher and first baseman (when defense is not objecting). There is no penalty given.]
