@Ken B. I wish I could find her a pitching coach closer than Little Rock. I would love to see her pitch with great mechanics. I will have to say she has came a long ways since we started this process, with no pitching coach. She is topping out at 48 at 10, With better whip how much more speed, revs would it make that much difference?
I missed a key part of your post. 48 at 10 is pretty good. I wonder if the lower quality of the video is disguising some whip. Can you can bump up the quality settings on your camera, or borrow something a little nicer and post another video from the side?
