I have a first year pitcher at 14u who is an athletic, coaches dream. She is already averaging 55mph, and will practice her tail off everyday if we'd let her. But on game day when we need her to pitch, she clamps up and her fear of failing is overwhelming. She'll get a horrible attitude and basically refuse to pitch. We only had two pitchers because one is out with an injury while my other starter has good movement but is lacking speed (low 40's, decent teams eat her pitching alive). I really needed her to throw but she wouldn't. So I benched her for three innings even though she's probably my best overall player. Right, wrong, or indifferent.... thoughts?
I would have your team read a couple different books. For starters:
10 Minute Toughness
Heads up Baseball
Play Big
Our coach made our girls read a chapter a week and send him a report on their take aways from each chapter. They are in the middle of Heads up Baseball and my DD approach to the game has changed 100%. All the girls look so much stronger now it's crazy! You can get the books used on Amazon for next to nothing.
If you dont want your team to read then definetly tell the kid about the books, it will change her life!
