Little League Rule 1.12 - A catcher must wear a catcher's mitt(not a first basemans mitt or a fielders glove) any shape, size or weight consistent with protecting the hand.
I would at least go with an 11 inch glove and possibly an 11 1/2. The 9 inch gloves are really small and will not be usable in a year or two. I would recommend that you get a glove that is game ready....it is basically broken in for you. I do not typically agree with the charts out there that recommend the small glove for this age.
A small size glove
perfect
