USA Softball of Pennsylvania is formerly called the Pennsylvania Amateur Softball Association (PAASA)/USA Softball. We are a national volunteer driven, not-for-profit organization based in Oklahoma City, OK. USA Softball was founded in 1933 and has evolved into the strongest softball organization in the country. The growth and development of the association led the United States Olympic Committee (USOC) to name ASA the National Governing Body of Softball, pursuant to the Amateur Sports Act of 1978. In 2015, ASA/USA Softball announced a re-brand of the organization to USA Softball, which would be effective September 1, 2016.
