batting stance

Question
My son is small, but a power hitter.  He is a lefty that bats right handed.   (he is a Pujols fan) He has a wider stance than most kids and is low- But has always batted this way - WIDE- His coach is now telling him that his stance is too wide. ( Is this true or should we encourage him to keep the wide stance.

Answer
Jacki,
    To comment on the first part of your answer, you son has the perfect combination of hitting and throwing.  I believe it is best that you hit opposite what you throw.  Your son throws left handed which (I assume means he is left hand dominant), this will put his dominant hand on the bottom when hitting.  The bottom hand is the power hand in the swing so most players who hit this way have more power.
    There are too many coaches who try to get every player to fit the mold they are looking for.  Most players don't have a wide and low stance like your son.  The stance is the one thing that a player can make his own.  Everything else after the stance needs to be the same and usually is.  As long as your son gets to a good load position, good step, good rotation, and lets the hips do the work not the hands, and has balance through out he is o.k.  
    Some of this hitters I train have wide stances.  In a wide stance you should not gain ground toward the pitcher when you step.  If you do gain ground when you step it will make your base too wide and the weight will be stuck in the middle.  You want to start balanced, upon the step be 70% back and 30% front foot.  Upon rotation and contact the weight should be balanced again.  
    The only other problem I can see your son having is getting too low.  Make sure if he goes crouch down its by his knees and not his upper body.  If he crouches his upper body his head will not be level.  Also you want a vertical axis of rotation and with a crouch upper body this cannot happen.  The vertical axis is made by the back knee, hip, and shoulder.  
    If your son does not have any of these problems than he should not have any adjustments to make.

Please let me know if I can help with anything else or explain anything further.
Thank You,
