>>> My almost 10 year-old son has developed a recent tendency to over rotate his back foot when swinging, to the point where his back side collapses and he loses balance. I'd estimate the foot has turned 50-55 degrees from its correct starting point at contact.

Any advice on what causes this and what can be done to fix the problem would be appreciated. <<<

Hi lbj

I may have misread your post, but I am not sure your son has over rotated his back foot. The back foot should rotate about 90 degrees from initiation to contact. Take a look at some of the batters at http://www.youthbaseballcoaching.com/swings.html and see if he rotates his heel past their position.
