I don't doubt her talent, she's clearly a great player. It's somewhat niave to believe that there aren't several equally talented girls around the world, but it's obvious that she's very good. You are right in the fact that she doesn't need to be playing in a state golf association if she wants to pursue a career in golf, but instead needs to be playing in national events.
I'm not trying to continually hype our local girl in comparison to yours, but IMO she fits the description of phenom much better. Granted, yours has 4 more years to accomplish her attributes, but here is an excerpt from Emma's bio that she compiled in high school.

Winning state events by 10 strokes is one thing. Winning national events by 22 strokes (as a sophomore) while shooting 18 under par is another.
