Girls Fastpitch Softball Rules

What are the Rules in Girls Fastpitch Softball?

That may seem like a simple question but the answers will vary. While there are some common fastpitch rules the specifics will differ greatly depending on what type of softball league or tournament you are playing in.  Most leagues will follow the rules set by one of the softball governing bodies. The league or tournament may also modify certain rules for a specific fastpitch softball season or tournament. A full set of rules and any modification should be available from the league or tournament organizer. The primary governing bodies are the American Softball Association (ASA), the National Softball Association (NSA), the United Specialty Sports Association (USSA) and the Independent Softball Association (ISA).

It is important to know what fastpitch softball governing body a league or tournament subscribes to in order to be in compliance with the correct set of rules. The rules may govern everything including the equipment, the players, the coaches, the field, safety issues, sportsmanship and pretty much anything that can happen on or around the softball field during a game or tournament.  This may include but isn’t limited to the type of uniform allowed to be worn, the type and size of ball being used, the number of innings or pitches a pitcher or catcher may participate within a set time frame, the type of bats allowed, what type of jewelry may be worn during a game, how long a game will last, whether all members of the team will bat or only specific set of players and how substitutions may be made etc.

While it can be confusing to stay on top of all current softball rules in effect for your team it can also mean the difference between a win and a loss. Umpires and officials are human just like anyone else and can make mistakes. This is especially true if they umpire different levels as the rules may differ from division to division. I would never advocate harassing an official but if a coach knows the rules (and even better has a copy of them on hand) then the coach can have a rational discussion with an umpire if you feel a call goes against the rules.  Please note that I would strongly advise against a parent confronting an official regarding a call or the rules. This is best left up to the coach and is their job, NOT the parents.
