A few thoughts from me
1) she isn't old enough to play in the junior am (they have an age-minimum); surely, they will create a rule in the off-season.
2) physically, men and women mature at very different ages. Men around mid-20s, women in their mid-teens. (Look at any major sport, younger women are at the top of the game in golf, tennis, swimming, soccer, etc.) I would argue that a 14 year old girl would win a US open before a 20 year old male
3) the womens qualifer is only 18 holes, compared to 36 for men. this alone will let more riff-raff in.
4) i am most disturbed by the fact that she has a website
5) When I take lessons in the winter, the person in the time slot before me in an 11-year old girl. She can already shoot low 70s from a 6000 yard course and has a swing i could only dream about. When she plays varsity next year as a 7th grader she will be one of the favorites in the state of minnesota. Based on this one example alone, i cant say that she shouldnt be playing.
6) look at scores from any women's am qualifer, 25% of the field doesnt break 85. hard to say a legit scatch golfer shouldnt be playing.
