>>> hi jack it seems to me if a batter went through all the necessary steps and arrived at frame # 2 in the middle mechanics as the model batter does in your swing mechanics his lower body is slightly opened and upper body is still closed his hands are still back behind him near his rear shoulder the knob of the bat looks to be facing the opposite batters box or the first base coaching box the natural hand path would be circular at this point for the hands to go linear it seems to me the batter would have to intentionally stop rotating and just push his hands in a straight line towards the pitcher but you say you do see batters still go linear at this point and I do believe what you say .I would also like to compliment you on your web site i purchased two of your tapes and like them very much but I also appreciate the free web site over the years i probaly bought about 50 books and hitting tapes and dont see anyone elese giving away so much information thak you <<<

Hi Jerry

Thank you for the kind words and I agree with much of your analysis of CHP mechanics. If, once attaining a good launch position, the batter would keep his hands back and allow shoulder rotation to advance them, the hands would be propelled into a productive circular path. This, along with THT, keeps the angular acceleration of the bat-head in sync with the acceleration of the hands and contact occurs well before the extension of the back-arm from the "L" position.

However, this not what occurs in most average hitter's swings. Rather than allowing shoulder rotation to accelerate their hands, they use the arms to initiate the hands. This results in the advancement of the hands being out of sync with rotation (disconnection) and also produces a less productive hand-path.

In the next frame, analysis of an average hitter shows the shoulders quickly rotating to take up the slack created from this disconnection. But it is too late. Bat-drag has been introduced and the swing can not regain its' potential. The batter's arms near full extension before the bat-head arrives with less velocity.
