Usually this caused by the way the ball is being held, and subsequentrly effects the release.
Where to start.
Check the grip of the fingers in relationship to the thumb.
Usually a "spinner" is thrown because the ball is being held with the middle finger and the thumb. The index finger is lazily lying on the ball. There are two ways to hold a 4-seamer. The best way to hold it for young kids is with the fingers across the "big smile" spread apart at the top of the ball in a "V" formation, and the thumb directly underneath. This assures that the ball is stabilized in the hand. However the same caution must be used in that the index finger cannot be allowed to lay on top of the ball and not used as intended to guide the ball to the target. If the index finger is not used to guide the ball it will be thrown with the thumb and the middle finger which automatically will create a curve, or slider effect.
How to fix...
Make sure that the thumb is offset beneath the ball so that the ball can only be released off the middle finger side closest to the ring finger to give the ball kind of a "screwball" effect. This will force the release to be more on top of the ball.
Pronation...
The normal release of a throw is with the hand turned inside, so that the thumb is turned down instead of up as it is ending up with your player throwing a "spinner".
So with a towel have your player practice the release so that he is using his hand so that he pulls the towel so that his "thumb ends up pointing down toward the floor.
When you play catch with him make sure you remind him on every throw to point his thumb down through the release.
left foot
Make sure the left foot is not hitting heel first. This jolts the body and causes the body to lose its momentum in the upper torso. As it reverberates throughout the body it acts as a brake to the throwing arm and truncates the throw so that it flattens out.
In stead of the throw continuing through to the 12 to 6 plane it flattens out to the 2 to 8 plane and creates the additional strain of allowing the hand to fall off the ball. This can also create the "spinner" effect.
Now there are some pitchers who use these techniques as off speed pitches, but they are not locked into it through bad throwing techniques. The correct way to throw the off speed pitch is by holding the ball deeper in the hand, not bad mechanics.
