If You're talking about her committing she's obviously not 12 and she must be a baller! In my experience in TB, say starting at 14U, but especially at 16U and up, most of my girls that split positions in the infield and outfield had two dedicated gloves for those multiple positions!I started this since DD's glove is 3 1/2 years old now. Well over 300 games. It is the only glove she has had her entire time in TB. It's a Rawlings LA that ceased being white a very long time ago. I fully relaced it a year and a half ago. At that point it would still hold itself open. Now it doesn't, but still holds a pocket when laid down. Still plays well. Balls aren't popping out or blowing through it. She plays OF and SS now, used to be mostly P and 3B.
I am holding out until we get more of a sense of where she will be spending most of her fielding time (IF or OF) and if she commits what brand they use, so it may be a Christmas gift. I am an equipment nerd so I have the "itch" constantly, and I know with this crowd I don't need an excuse.
But honestly you don't see many girls play SS and outfield, if you have a real SS, she usually stays at SS!
The way I look at it, in high level competitive softball, a real SS's glove won't work in the outfield, and a real outfielder's glove won't work at SS. Obviously there's exceptions to that but you get my point.
