NFHS 8-3-2

NFHS 8-3-2/OBR 6.01h2

Every time that a defensive player obstructs a batter-runner or runner, that player must be awarded at least one base beyond the spot where he was obstructed.

[OBR: when there is obstruction and a play was not being made on the obstructed runner at the time of the interference, there would be times the umpire protects or awards a runner “back into” the base he was retreating toward.]
