I am not a doctor so I won’t attempt to answer the age-old question of what is the right age for a pitcher to begin throwing a curve ball. No doubt, a curve ball can be a devastating pitch at young ages if it can be controlled. I’ll leave that up to an individual’s decision as to when is the right age to begin teaching and throwing a curve ball.

The Curve Ball Grip
The simplest way to find a curve ball grip is to grip the ball as you would with your 2-seam fastball, then rotate the fingers up towards the top of the horseshoe on the ball. Be sure to find as much seam as possible on the ball and place the middle finger with added pressure on the inside of the top of the horseshoe. The fingers should be closer together than on the fastball grip.
Curve Ball Coaching Techniques
The same techniques in all of pitching need to be emphasized while throwing the curve ball. For some reason, a young pitcher starts to concentrate so much on throwing the curve that he often loses some of his normally quality mechanics.
We remind the pitchers to stay back, stay closed, and follow through on the curve ball.
Arm speed needs to be the same as on the fastball, but the wrist is turned slightly close to the release of the ball. The pitcher proceeds with a karate chop motion through his delivery. It is good to emphasize that the pitcher should end with his right arm over his left leg.
The arm is not as extended when throwing a curve ball in comparison to a fastball. This is a good thing to demonstrate to the pitcher by measuring his reach while throwing a fastball and then measuring it with a curve ball. With the curve ball grip, he will not be able to reach as far out on his release.

I’m not a doctor so I am not going to pass judgement on the age at which young players should be throwing a curve ball. I’m sure that the proper age varies based on many factors including the mechanics and the maturity of the pitcher.
One thing that is for sure, however. Kids are going to throw curve balls so why not teach them the proper way to do it.

Here’s some tips on what to teach.
The Curve Ball Grip
- There are several grips to throw a curve ball, but all keep the middle finger and thumb on the seams.
- All of the pressure is with the middle finger and the thumb.
- The pointer finger does not give any pressure and is merely used as a guider.
- The pointer finger and the middle finger should be close together.
- The grip should be further back in the hand than a fastball, but likely not as far back in the hand as a changeup.
Arm Position on Curve Ball
- Teach that the arm position on a curve is exactly the same as a fastball up until the position where the hand reaches the ear of the pitcher.
- At the top of the motion, the wrist wraps the ball and the wrist is facing the ear of the pitcher.
- Be sure that the elbow is higher than the shoulder on a curve ball. This will create maximum break downward. If the curve ball is thrown from the 3/4 arm angle, the ball will tend to break more horizontally across the strike zone which is not preferable to a 12-6 curve ball with downward bite.
Wrist Action on Curve Ball
- On a fastball, the wrist is facing the catcher once it reaches the top of the arm point; on a curve the wrist is facing the head of the pitcher.
- Twisting the wrist in the fashion of twisting a door knob is not necessary. Rather, the pitcher snaps the wrist downward while spinning the thumb upward to create maximum spin.
- The wrist should never be in the position of being parallel to the sky similar to screwing in a light bulb. This is what causes elbow injury.
Follow Through on a Curve Ball
- The release point on a curve ball is at the front of the bill of the cap.
- The pitcher’s arm actually accelerates from the top of the throw through the follow through.
- The follow through should end higher than a fastball, at about the upper leg of the pitcher’s opposite side.
