> >>> I've posted on this site many times that I've experienced similar experiences with my 13 yr old son. After 3 yrs of rotational instruction his left shoulder was opening up too soon; the hands were going in circular motion, but the bat wasn't in the strike long enough to make consistent contact. He crushed inside pitches...foul. Outside pitches, changes and curves were death. <<<

It would be a mechanical issue if the axis of rotation (near the spine) was pulling away from home plate. This action of pulling off the ball is commonly interpereted as Rotational theory. Actual theory is to keep axis of rotation stable. If someone tells you that the front shoulder is coming out, it usually meant that the spine is moving away from home plate during the swing. If the spine remains stable, people assume the shoulder remains "closed".


Andy,

A lot of times a leaking front shoulder is NOT a mechanical issue but rather a timing and rhythm issue...the natural reaction to a fastball that is getting on the hitter is to get the spine/front shoulder out of the way to catch up to it.
