I have a couple of 12 year olds on our team who are fine hitters, yet both have the same bad habit of dipping their back shoulder to reach low or outside pitches. Any suggestions of drills to break this habit?

Williams, Ferroli, Epstein, and countless other rotational instructors will argue that the back shoulder must lower in order to enable "the plane of the pitch to match the plane of the swing." Even Mankin and Elliot would agree that the back shoulder must lower into the swing plane, the only difference being that the former would stress making an conscious effort to do so, whereas the latter would say that this is just an action that happens as the swing progesses. Although I favor the former, the latter point of view has just as must merit. I have just read Adair's "Physics of Hitting" for the twentieth time, and he also agrees that the bat is traveling upwards to meet a ball traveling downwards at impact.

Yet, one online article that pertains to the science of hitting a home run argues that trying to self-induce these results (i.e., changing the "rotation" on a hanging slider) will produce "negilible" results. Seen in this light, Lau-based theories are purely anecdoctal.

From a geometric perspective, dropping the back shoulder should assist an individual in waiting for and rotating the bathead to the outside part of the strike zone. Contrary to popular believe, dipping, whether conscious or unconscious, is an integral part of the baseball swing.

Black Hole Lexciographer, i agree with you....i'm not sure why anyone would think some shoulder dip is bad....i do remember when my son was in t-ball he had a bad habit of dropping hadns and dipping shoulder, but that was long before he learned all the other mechanics of a great hitter....as long as shoulder dip is not excessive, shoulder dip in itself is positive not negative....
