Greetings all --

The link I had to a pretty comprehensive article describing (in clearer more understandable language than the ASA rule book) the basics as well as finer points of the ASA/JO DEFO/DP substitution rules has become a dead end, and I can't even recall where the link took me.

Does anyone here have any direction to a good, basic primer on the hows and whys of ASA specifically girls fastpitch rules about these confusing substitution rules?

Thanks.
