FAS was organized originally to promote the participation in, and administration of, adult softball in Fairfax County, VA on behalf of the individual participants at all levels of play and we have stayed true to our cause. Click the image above for information about what softballs are legal to use in FAS games and to order by the dozen. Our three distinct seasons of play and Fairfax adult softball of varying Fairfax adult softball levels offer the entire community an opportunity to compete at the levels they are most comfortable with, as well.
