This rule is still at BBFL. If it was changed, I usually go in immediately and alter it. I'm getting senile so I might have missed it. Was it just an idea or did we actually vote on it? I think disallowing a player from RP status because of one start is rather drastic.
ii. Any pitcher that has started 3 games in a season is an SP. If used as an SP in minors, must be, without appeal, an SP in MLB
