I have a 10 year old and I'm looking for a glove. She has never been interested before. She has gone to countless baseball games to watch her brother as well as my slowpitch games. For the first time on Saturday she picked up a glove and wanted to play catch with us (I have begged and pleaded with this girl to have a catch for years and she always says No) needless to say I was in shock! She had fun, caught some balls and threw pretty well. The issue I have is she's a lefty and the rest of us are not. Otherwise we have plenty of leather laying around. I want to get her a glove and hopefully build interest for the game. She is a little over 4'6 and weighs around 85 lbs. She has sturdy build and would probably make a good 1st basemen someday. Hand size I'm not sure, but she is bigger than most of her friends the same age. Is a youth 12" too big or should I go 11.5? What size ball do they use 11 or 12? I've been looking at the vinci youth gloves a bunch as I game one myself. She might like having the same glove as Dad! Any advice or thoughts would be appreciated!
