I think it crazy for OF's to wear a mask. My son plays little league and for the most part these players are not any better than the girls and the ball is harder gets hit harder and I've never seen a player wear a mask. A few wear when they bat but very few. It's a flaw in the girls game that I see. They should have division like little league does versus strictly on age. You see girls who are 11 playing 12U that can't even turn their glove in the right direction but have to play there when they should be playing AA or some other level.
