> > > I think one of the main reasons rotational hitters (chp & torque)are leading the performance stats is because there is less need for the batter to change his swing mechanics or timing due to pitch placement. He is able to use the same basic rotational mechanics regardless of where the pitcher throws to him - and still hit the ball hard. The adjustment he needs to make is a slight change in how he initiates the swing. Once that change is made - his mechanics for the balance of the swing is on autopilot regardless of where the pitch is.

This causes the back elbow to come almost straight down to the batter’s side. This also keeps the lead arm across the chest and generates a tight hand-path and thus a low-load resistance to shoulder rotation. The back elbow coming more straight down with little body rotation during initiation, means top-hand-torque was applied over a limited amount of time. But with full shoulder rotation (lead shoulder pulling back toward catcher) at contact, the batters finishes the swing with a lot of bottom-hand-torque.

> > On a pitch more in the middle of the plate, the pull of the top hand is more straight-away or at 12 o’clock. With a more straight-away pull the shoulders rotate a few degrees as the back elbow lowers to the batter’s side allowing a greater amount of time to apply top-hand-torque. This direction of pull also causes the lead arm to cast slightly away from the chest and generates a somewhat wider hand-path. A wider hand-path generates greater bat speed and a higher load resistance to shoulder rotation. Less shoulder rotation means less bottom-hand-torque. So on the pitch in the mid part of the plate, what we wind up with is greater bat speed from a wider hand-path and more balance between bottom and top-hand-torque being applied.

This direction of pull causes the back elbow to sweep in a wider path and slows body rotation. This allows top-hand-torque to be applied over a much greater portion of the swing. This direction of pull also causes the lead arm to cast out farther and develops a wide hand-path and thus a heavy resistant load to shoulder rotation. A more limited shoulder rotation equates to little bottom-hand-torque being applied. So, on the outside pitch the swing produces a wider hand-path with a lot of top-hand-torque and little bottom-hand-torque. <

> >>> All that pulling the top hand to different postions on the clock - sounds alot like "throwing your hands at the ball" Jack. I would never tell my hitters to do that - it is inconsistent with everything you advocate. If you tell a hitter about the clock, I guarantee you are asking for trouble. Do you have video or examples of MLB hitters that do what you say, Jack?

> The direction of the hands while applying top-hand-torque is directly OPPOSITE to that of "throwing your hands at the ball." So I really can not understand how you drew your conclusion. By definition, "throwing your hands at the ball" requires a FORWARD thrust of the hands at initiation. Applying top-hand torque requires the top-hand to PULL BACK (toward the catcher) at initiation. This pulls the bottom-hand and lead-arm tighter across the chest as body rotation starts.

> I would have to agree with you that using a clock was probably not the best choice to describe the direction of pull of the top-hand. But, at the time, it was all I could come up with. Maybe describing it as pulling the top-hand back toward the catchers left shoulder on inside pitches and at his right shoulder on outside pitches would have been better. --- Regardless of how Barry Bonds describes how he hits outside pitches, a video analysis of Bonds’ mechanics would exhibit what I stated above.

> I think Jack and I describe the same action but I have not been able in my own swing or been able to use with my hitters sucessfully as a cue of pulling back with the top hand to initiate the swing.To me hitting is about feel and to me I believe the The rear elbow and upper arm which are bigger muscles initiate the swing [as opposed to the hand] as the front heel comes down.As the elbow comes down it pulls the top hand and barrel back,now as the top hand comes back from the rear elbow down[forearm and hand control the bat to get it on plane which is assisted by the lead arm and the posterior lead deltoid which flexes as the lead elbow works up[epstein].This is all for the minor adjustments after posture sets the body for the main plane to the ball.In the load as the rear elbow is raised I feel the rear posterior deltoid flexed then is stretched as the rear elbow comes down,so as 1 deltoid is flexed the other is stretched,[much how we feel the workings of the 2 scapulas].Now back to elbow slot;On the away pitch we must plan to hit it 1st because we must hit it further back which is closer to where our bat is.The elbow slot on the away pitch is further away from the body which does allow for a larger radius but it also flexes the anterior deltoid of the rear shoulder and directs it toward the ball going away and I believe it seems to flex earlier and stonger in this position[allowing for a higher load[tom Guerry]]Than it does when brought down to the ribs for an inside pitch ,in which it is not in as strong of a position until later on for an inside pitch.I don't get much out of teaching this but I have came up with a drill which I am sure someone else has created some where.I use 2 tees,I put 1 on the o.s. corner and near the back corner and have them work on hitting the ball away,Contact is somewhere near inline with the hitters crotch.Once they get it down I then add another tee which is 4-6 inches higher,and I put it about 2 inches in front of the plate and inline with the inside corner.Now they think about hitting the o.s. pitch but as they begin to load and stride[which is when they decide on a pitchIMO]I either say outside or inside and they swing to that ball.It prepares them to hit the o.s. pitch 1st and adjust to the i.s. pitch that they hit later.I also find that they seldom hit the inside tee when they are hitting the o.s. ball because the uppercut rides the bat above the inside ball.On the mental end I teach them in 0-0 1-0 2-03-03-1 to look middle in or middle out whatever is their strength is or what they think the pitcher is going to throw,but other counts we must try to cover the whole plate and this drill helps prepare them to initiate properly and adjust inside.
