My soon to be 13 year old has done some catching in local ball and would like to try at a higher level. She has been using a Mizuno first basman's mitt to this point, but to catch a 50-55 mph pitch, she will need a proper mitt. I see mitts that are 32.5" to 34". I am used to seeing gloves that are 12.5" to 14" for fielders. I am out of my element here. Any suggestions?
