I have a pitcher on my team who is very accurate when throwing to her mom. At our team practices and during games when she is throwing to one of the team catchers, she becomes inaccurate and wild with lots of balls in the dirt and high above the catcher resulting in lots of walks and stolen bases including at home. At practice the other night, I had her throw to me so I could see what she was doing. She threw great to me. She had a slight bend at the waist so she focused on staying tall and she threw great. Hardly any balls in the dirt or over my head. Last night at practice, I had her throw to one of the team catchers. Again, she was all over the place. I reminded her about staying tall because she had a significant bend at her waist while throwing to the catcher. She had a difficult time correcting the bend. She complains that the catchers don't catch her pitches. I believe when she is throwing to me or her mom, she trusts us to catch her pitches and throws without guiding the ball resulting in better accuracy. When she throws to the catchers, she does not trust them causing her to guide the ball (hence the waist bend) resulting in inaccuracy and wildness which leads to more balls by the catcher. We actually have a good catcher that is able to catch her but is pushed to her limits with the wild pitches. This seems to be a vicious cycle and mental. Any suggestions? My thought is no more pitching to an adult so that she becomes comfortable with a girl catching her but I don't know how realistic this is given how often pitchers practice outside of team practices. Pitcher is 12 YO.
