What happens when a fly ball hits the Foul pole?

Answer 1

It is a foul ball and runners return to the base they occupied at the time of the pitch.

If the batter has less than two strikes, it is a strike. If the batter has two strikes, it remains two strikes, unless the batter was bunting, in which case the batter is out.

Answer 2

Foul poles are poles that are placed vertically on a Baseball field. They mark the areas where an umpire must look when determining if a ball is foul or fair. If a ball hits the foul pole, it is considered to be fair, and thus a home run.
