Conclusion. The four-seam fastball, two-seam fastball, and change-up are all the pitches a 12-year-old will need to throw. At this critical stage in their development, throwing pitches that create torsion on the wrist and elbow can ruin their game prospects.
James Andrews (renowned orthopaedic surgeon and medical director for the Andrews Institute) recommends that youth pitchers refrain from throwing curveballs until they have mastered the fastball and change-up and are at least 14 years old4.
Push Off the Rubber
Remind pitchers to not just stand in front of the rubber, but push off it on every pitch. This will allow your hurler to feel like he’s pitching “downhill.”
Ages 11-12 – 85 pitches per day. Ages 9-10 – 75 pitches per day. Ages 7-8 – 50 pitches per day.
Make sure that you’re gripping the bat firmly, but not too tight in your fingers. This will keep your body relaxed and allow you to make the best contact with the baseball. Your grip will naturally tighten as you generate your swing.
Lining up door knocking knuckles prevents the shoulders from dipping, eliminates a looping swing and allows the hands to properly carry the barrel of the bat to a solid point of contact with the ball.
The strongest position is when your bottom hand palm is facing down, and your top hand palm is facing up. If you open up your hands they should both be parallel to the ground. As you make contact, your grip will naturally get tighter and your top hand thumb will not allow the bat to get knocked backwards.
Unless you throw the ball straight over your head, you won’t be able to get ‘12-6’ rotation without moving your wrist. As the ball comes forward during your motion, you will want twist your wrist to keep your hand as vertical as possible. This is the key to having good ‘12-6’ rotation on the ball.
As you bring your arm around in front of you, release the ball when it lines up with your target. Move your body forward with your throw. As you prepare to release the ball, take a step towards your target with your leg opposite your throwing hand. If you are right-handed, you will take a step with your left foot.
