The compression on NSA softball in official play is 275 pounds on a .52 c.o.r. ball, with the men using a 12 inch ball and the women using an 11 inch ball. The ASA, on the other hand, uses a .52 with a 300 pound compression.
12" balls i believe
11" circumference for women's slow pitch softball.
Fastpitch softball ASA bases are 60 feet apart.
There are a number of associations in softball but I will presume you are asking about ASA (amateur softball association).
There is ASA softball which is club team in a way like AAU
If by leagues you're asking about sanctioning bodies such as USSSA, ASA, USFA ect. The difference is the level of competition.
There is no limit to the drop; that only applies to baseball. The only requirement for a softball bat to be used in high school softball is that it must be ASA (Amateur Softball Association) approved and so marked on the bat. The current marking is the phrase ASA 2004 inside the outline of a home plate.
asa, usfa, usssa
NO
In the U.S. and possibly other countries, any the ASA (Amateur Softball Association) approve are legal. The bat would say ASA approved somewhere on it. This applies to women's and girl's travel teams and school teams.
An approved bat is a bat that has been tested and is approved by ASA. ASA stands for the Amateur Softball Association. Bats that are approved will have a stamp towards the cap of the bat that looks like home plate and it will have a year in it.
no they don't. Only the catcher does
