Fastpitch Softball Ball Regulations for 12U Tournaments

Question
What is the regulation size and type for tournament play?

Answer
Hi Mike,

Thank you for your question.  I gleaned all of the information in my answer from 2010 ASA Rule 3-3...it's four pages long!  As with every ASA rule, it applies to Championship Play.  12U and older fast pitch girls use a 12" circumference ball.  It may be optic yellow or white.  Seams must be red and flat.  The ASA certification mark/logo must be red.  Finally, there are two more technical requirements: 1) a red Coefficient Of Restitution (COR) mark of .470 or less 2) a red Ball Compression mark of 375 lbs. or less.  Whew!
