The Saturday Softball League, or SSBL, was created in 1977. SSBL's main activity is to provide a softball league which runs on a weekly basis during the late spring and summer time. The purpose of the league is to allow gay, lesbian, and bisexual players to gain experience and develop softball skills within a formalized structure. The league membership includes both men and women, heterosexuals and homosexuals, young and old. The league play is governed by rules set forth by the American Softball Association and the league body.
