One of my problems (I have several but they have been mostly mentioned above) with the Kentucky rule is that it doesn't apply to baseball. One of the proudest moments I've had as a father is when my daughter told me she didn't want to wear a face mask because the boys don't and she's a better fielder than them. Heck yes!
There's an element of this rule that smells of sexism and I don't like it one little bit.
Or the fact that the distances are shorter and the girls are hitting just as hard.
