Yes, Hurricane the duct tape is to prevent dads, moms or whomever from opening their mouth and speaking between every pitch or swing. (over critiquing)
Due to her selective hearing at 12s and 14s, my voice was either too demeaning and harsh or annoying and over bearing.
Making fun where she got feedback and visual results was my answer and solution.
I only had one student (her), but was 100 percent correct on method of improvement.
In regards to hitting, she saw how and where the ball flew, she corrected herself and made adjustments to improve.
So when she saw her hitting coach there was only tweaking, and learning insight.
In regards to pitching, (she pitched at 12s and first year 14s) She practiced with a target wood frame and canvas target I made.It did not argue zone, or criticizes. She gave up on pitching because it just took too much time, and took that extra dedication. Which was cool with me.
If I did it again, I would have set up a radar reader, kinda like a carnival game.
So when she pitched the ball and it went through the frame it would show a speed of pitch to her. Now this doesn't help on movement, but she would throw harder just to improve her immediate score, that is just self nature that kicks in.
