What about hitters that toe the line with their back toe but stand open per Louisiana at Lafayette? That is also how my dd steps in the box. We work very hard at her being able to hit that inside pitch out. We do what we call, "the progression drill" where I throw at her front hip. She has to drive that ball or get hit by it.
If your DD can hit an inside pitch, and by "inside" I mean on the black or in the river, out of the park, then all a pitcher can do is give her a "golf clap" while she rounds the bases, because that is impressive. A lot of pitchers throw a ball slightly inside of dead center, and call it an "inside pitch", while great pitchers live in the "black".
