I never really worry about it playing in Men's League, because I haven't ever had any incidents in two years and there have only been a couple I've seen in person, but my heart goes out to this girls family.
I was laughing when I was watching my friend Macey playing slow pitch in her girl's league here in town and that the catcher and the hitter were wearing helmets, I never understood why - and I laughed, but now I can say I regret laughing.
I don't know if this calls for helmet's in the field though.
That same game, a girl got a line drive in the face and broke her cheekbone, but I think a lot of it had to do with poor coordination, but it's still concerning.
Playing catcher, I get a lot of foul tips coming at a fast pace behind me. I always change up my stance (not even close to a normal catcher's stance in baseball, depends on the count and the pitch) based on the batters stance and what side of the plate he plays on. If I wouldn't do this, I'd probably be sliced in the face every damn time a ball goes back.
Perhaps this is just a wrong place at the wrong time thing, but I think a lot of injuries like that, in regards to softball could be helped with a little knowledge of the game and more practice.
Still really sad though.
