ISA Slow Pitch is the most dynamic version of the game played.

ISA originated employing rules such as the ISA pitchers box, base stealing, the base burglar and legitimate home run rules in accordance with today's bats & balls.

Our program is an exciting fast paced version of the old ball game.

No longer dependent on offense only, ISA has reincorporated defense as an integral facet of the game.

For a version of the game imitated by many but unmatched by any, play with the originator, the ISA.
