Thank you, her change from 35' to 40' plus adding in the 12" ball made very little impact on her. So, I am sure I am making more of this than I should....but I just wanted to be ahead of this. You are 100% about it being mental....so, I really won't even discuss it with her unless she brings it up. If she can add 5' (35-40) and a new ball with no issues than I am sure 3' will not be an issue. Thanks for the thoughtful reply.
Just for giggles I'd like to respond to transitioning from 11" ball to 12" ball. Thank you for the kind words by the way. There's many ways to interpret a post and my intention is never to hurt anyone. Some can be sensitive to my answers but I try to be respectful, especially to concerned parents having their child's interest as such a priority.
Many instructors never teach pitching with an 11" ball. no matter the age, they use the 12" ball for a variety of reasons including encouraging the kids to stretch their fingers over the larger ball to help strengthen the grip. Even older girls are some times made to use an old "Chicago Style" slowpitch ball that's 14" or 16" in size. Not sure of the exact measurement. Years ago it was very popular in the Chicago area to play with these huge balls rated with lower core and compression and normally played in fields with much shorter fences. You should try to hit one hard some times. It was like trying to hit a cantaloupe out of the park! Anyway; I understand the concept of practicing with a larger ball-------i simply choose not to do it myself.
My instruction deals with getting the girls to properly hold the ball with comfort and work on having a loose wrist with control to promote spin and wrist snap. By stretching the fingers you can get a stronger grip but it also can promote a locked wrist. This can effect both a forward snap as in the fastball and side snap in spin pitches like the curve. I'm big on movement. Let's be honest; some/many girls are limited physically on how hard they may ever throw. We cannot overlook this and people need to know many cannot overcome it and still have control. BUT, if a girl with average velocity can learn how to spin the ball and create movement she easily can be a front line pitcher at any level. I wish more coaches would listen to this because many are wasting their opportunities to cash in on some real talent. They are stuck with the mentality to "Blow it by them" instead of watching batters twisting out of their cleats trying to hit a breaking ball. Just like a good change up, you can make a hitter look pretty silly with a good breaking ball.
I have girls using a soft ball like a racket ball (personal favorite) or doggy chew toy, something with light resistance, and keep it with them all the time. While watching TV or playing on the computer, riding a bus or in the car, simply take it in hand and practice squeezing it while flexing her wrist in the wrist snap motion. This builds up the fore arm muscles that will give a stronger wrist snap. Good for everything in this game. We want flexibility in this game and toning the right muscles can pay dividends for a pitcher-------or any position player. Conditioning is just that. Pitching lessons with me (my name) focus on mechanics and fundamentals. I want the girls using the size ball they plan to use for the season to get comfortable with it. Personally, I don't use the larger balls during our 1-hour sessions.
