> >>> The following pics reveal the bat is not on plane with the lead arm but rather the plane of the lead arm wrist cock . The rear arm is perfectly on plane with the bat.

> You must have a very different definition of the swing plane. Take a look at this clip of Bonds full swing http://www.youthbaseballcoaching.com/mpg/Bonds01.mpeg . Note that at about frame 30, he has swept the bat behind his head and into the plane of the lead-arm and is ready to fully launch his swing. From here to contact, the bat, lead-arm (and elbow) are in the same plane. Also note, that the back-forearm is not in that plane. In fact, it is almost perpendicular to the plane for much of his swing.

> Therefore, since you feel it is the back-arm that stays in the swing plane instead of the lead-arm, it would be helpful if you would define your version of a swing plane.

*******************************************************************
Grab a bat in your lead arm hand only. Swing one handed. Does that bat remain in the plane of the wrist cock/uncock motion and not the arm? Only at full uncock does the bat APPEAR to be on plane with the left arm. Now grab a bat with the back arm hand only. Swing one handed. Does the forearm and bat reamin on the same plane? If you are not sure place your forearm and bat on top of a flat table top.
Are they on the same plane?
