I've stated here several times, no catcher in my house. But for off season help/work, if possible have her go to pitching lessons with her HS or TB pitcher to stay sharp on tough pitches out of the zone. And to get to know the habits good and bad of that pitcher to know how to handle her in tough game situations.
She had been catching for her old teammate's lessons, but her friend moved away. She said none of the pitchers left on her team are taking winter lessons. I guess I should check with the parents directly.
