Calling penalty hinders during a racquetball match plays an important part of keeping racquetball a fair and honest game. A penalty hinder does not necessarily have to be an intentional act. There are many types of penalty hinders, but the most common falls under Rule 3.15 (a) Failure to Move. It is not allowed to stand in front of your opponent’s shot either straight to the front wall or cross court. See below for more information on penalty hinders.
