Illegal Player - NSA Fastpitch Rules (related to other illegal player post)

[Dakota]

There are two main rules philosophies regarding unreported substitutes: the first treats it like a minor offense the first time (assuming it was an eligible sub that merely entered unreported). Rules that do this are NFHS (high school) and USSSA; the second treats it as a major offense with more severe consequences. ASA is in this category, and apparently, so is NSA (I don't know NSA rules - just going by what you posted). In this case, the offending player is disqualified (ASA) and apparently ejected (NSA), and there can be other penalties, such as an out, depending on the exact situation.

Also, these are 3 different things:
1) Unreported substitute
2) Illegal player, and
3) Ineligible player

Umpires generally do NOT rule on player eligibility. This concerns such things as age, etc. Umpires do rule on unreported or illegal players.
