If they are pitching correctly, with their fingers and wrist, they will be in line with home plate after they finish their delivery. This has a tendency to embarrass the kids. As pitchers, they have a tendency to slow down their motion to get the ball over the plate to avoid hearing the negative comments. When this happens the batter has the advantage instead of the pitcher. At the Academy, we teach kids the ability to recognize and focus on their movement instead of what they are hearing in the stands.
Success begins with the athletes pleasing themselves.
Next time you are in the stands, put yourself in the athlete's place and be supportive.
