What is the NFHS "Look-Back Rule?"

[ENTDoc]

There is a difference in the look-back rule in NFHS and ASA. In ASA, if the pitcher makes a play or fakes a throw on any player, the player is exempt from the penalty of being called out. This is a quote from the NFHS softball rules book in section 8-7:

"EXCEPTION: The runner will not be declared out if a play is made on another runner (a fake throw is considered a play), the pitcher no longer has possession of the ball within the 16-foot circle, or the pitcher releases the ball on a pitch to the batter."

So, if a pitcher makes a fake throw on a player to get her to return to her base, will not be exempt from the penalty of this rule. Also, if multiple runners remain between bases according to NFHS rules, only one may be called out in any given play.
