Is it ever a meritocracy! Just look at the levels: Peewee league, Little League, Jr. High, HS, college, rookie league, single A, double A, triple A, and then finally the MLB. I'm not even counting the independent or foreign leagues. (Even Japan is only about Triple A level.) The NFL and the NBA do not have these levels. So the point is that the levels weed out anyone not MLB material, and the MLB itself is the best of the best of the...keep counting. It would take a genuine miracle, meaning an act of God Himself for a woman to get past all of those levels to the MLB.
