Ball is hit behind batter and spins to the front of batte fair or foul?

Not sure just exactly what your question is, but I think you're asking if a batted ball hits behind the batter and spins onto fair territory, is it fair or foul.

Answer: provided it was not touched by any one or any thing, it would be a fair ball. Inside first and third base, a ball is determined to be fair or foul by where it comes to rest or where it is first touched.
