In the meantime, go out today and get the Evo-shield thumb guard, or order the Endoskel guard on Amazon (Amazon product ASIN B06XKKDG6S). $25-$30 of well-spent money to avoid a lifetime of thumb trouble. Have her use those until whatever new glove you end up with gets broken in. Even then, IMO, I'd keep using the Endoskel. (I have one in my Vinci baseball catchers mitt. Much greater protection than my mid-range Mizuno, but I'm still susceptible to re-injury. The endoskel fits perfectly into a new glove. The evo shield may only fit on a well-broken in glove).
