There's not much you can say or do that will make her feel more confident about pitching. Have her work hard on hitting the inside corner as a primary pitch location and changing speeds. Everything that hangs brings the possibility of line drives up the middle
Before her second game last night we talked about going inside and up with her fastball, so if she doesn't have a feel for where to go....go up and in by default. As she seemed to get more comfortable in the circle as the game went along, then started mixing speeds. Will keep working on that at her lesson today and also our games this weekend.
