Sounds like the problem is between her ears. The mental side is quite the paradox, it's both the most important part and the least covered part of a pitcher's training.So my DD has great velocity long toss and "walk ups" but sometimes she struggles to bring this to her "off the rubber" deliveries. Other times she carries it over no problem. I think she maybe overstrides, any quick fixes? Or common problems here. No video as of yet. Its hit or miss.
