Slow pitch emerged as a popular division within USA Softball in the early 1950's.  Added to USA Softball's Championship program in 1953, at the National level, USA Softball annually conducts National Championships in the adult slow pitch division while many state and metro associations offer tournament and league play at the grassroots levels.

Each state/metro association may offer additional opportunities for league or tournament play.
