Failure to return

Any of the following constitutes a failure to make a legal return during the rally:

1) The ball bounces on the floor twice before being hit.

2) After contact, the ball fails to reach the front wall before touching the floor.

3) The ball goes off a player’s hand or fist into the gallery, into any opening in a side wall, or ceiling.

4) A ball that obviously did not have the velocity or direction to hit the front wall strikes an opponent.

5) In doubles, a ball struck by one player hits that player’s partner.

6) Committing an avoidable hinder (See Rule 4.8).
