This rule states that if a defensive player does not have the ball, she cannot stop the runner from reaching the next base. She could stop the player by standing in her way, or putting her leg down to block a slide before she has the ball to tag her out. A catcher can also block the plate by not allowing the runner a clear path to the plate when they do not have the ball. If a player does have the ball, they are allowed to block the bases though.
No there is no framing rule.
No, this is considered an unintentional obstruction. Interference is called on players not objects.
No, but there should be.
7 innings unless there is a mercy rule
There are many rules in softball but there are different leagues. Post a question more specific about what type of league and you may receive better answers.
I assume you are referring to the international tie breaking procedure. It can be used as a state adoption. Please check with your states high school athletic association to see if they have adopted the rule.
softball has 7 innings in less a tie then they play more innings if one team is winning by a lot they have the mercy rule and they call the game
Its a 5 point mercy rule
8 or more runs after 5 innings.
Other than its initial introduction, the obstrution rule has remained unchanged (except for wording and clarification purposes).
Pay attention to the game at all times! Know where your runners are, and if their covered.
