Grand Slam ends the game?

If I'm not mistaken, as long as Runner on third touches home, and Batter touches 1st, it is a legal advance, game over.

That's the OBR rule -- and it might (there's controversey over the meaning of "any other play") only apply on an "award" -- e.g., walk, not on a hit.

THe post specified NFHS rules -- where all (forced) runners must touch the advance base.
