And this type of contact frequently results in a weak grounder to the pull side.

That same hitter should then contact a middle pitch closer in, for example 9 inches in front of home plate. And the outside pitch will be contacted perhaps even with front edge of home plate.

It's a physiological concept ----- On an outside pitch you have to REACH to get to the ball. If you don't "reach" you rotate the sweet part of the bat AWAY from the ball. If you "reach" with body lean you inhibit hip rotation. If you "reach" by fully extending the top arm, you again inhibit hip rotation. I'm with you all the way with rotational hitting when it comes to hitting an inside pitch, but you need to overcome this notion that what works for an "easy-to-reach" inside pitch will also work for a "harder-to-reach" outside pitch.

And if you don't understand them, beware, Tom G. may unleash another one of his novels on you.;) God bless him, if it weren't for his novels, I would never have found this place and would still be muddling along somewhere between linear and rotational without knowing the difference.

The clip on the right shows him hitting a ball over the middle of the plate. What would you say about the contact point as far as how far in front of the plate contact was made? And is the handpath circular or linear in your opinion?

I see a heel drop triggering hip rotation with a nice separation before torque generated shoulder rotation connected to the bat with the tight linkage of the front arm followed by a further tightening of the arc, or arcing handpath as I think Jack says, (iow, less linear) to adjust to the inside pitch location.

> > I've just tried to digest all the discussions at once this morning. IMO the disagreement is more of a disconnect. Let me explain -
> > Saat is right in that if you rotate fully (complete hip and shoulder turn) you will eventually start to pull off the outside pitch. However Jack and company have never stated that you hit an outside pitch with full hip and shoulder rotation.
> > The concept as I understand it is that hip and shoulder rotation is cut off earlier for an outside pitch to avoid turning past the ball and pulling off. Additionally, rotational hitting does not hold as its ideal, a complete pivoting spin of the body around 180 degrees or 360 degrees. Fact is the shoulders turn somewhere in the 90 degree neighborhood ( I don't want to quibble about a few degrees of counter rotation, etc.)
> > This approx. 90 degrees (or more or less)of shoulder turn is created by hip rotation/torso transfer to shoulder rotation. At or near contact, the bat should be released from the shoulder rotation circular path.
> > If you are totally rotational and the bat remains parallel to the shoulders (turns with the shoulder turn only, no release) then the shoulders would have to turn a minimum of 45 degrees from perpedicular to the pitcher to hit to the opposite field line; and 135 degrees to pull one directly down the line.
> > While this is a wide range of shoulder rotation, consider that the work/energy supplied by the quads, hamstrings, glutes, abs, obliques (core) happens one step earlier in the kinetic chain than the shoulder rotation. Transfer of lower body energy to shoulder rotation should happen at maximum hip rotation SPEED, not at the end of the hip rotation path and this is somewhere in the middle of the hip turn. If the hips turn from sideways to forward that is 90 degrees. Max hip rotation speed would be somewhere in the middle - maybe 45 degrees of turn or later and before 90 degrees.
> > The point is that the hip turn has supplied plenty of power in the first 45 degrees of its turn to power the shoulders well even at a 45 degree shoulder turn - the absolute miniumum point where releasing the bat will hit the ball fair to the opposite field.
> > The disconnect in the weekend argument IMO is that Saat thinks the hands/shoulders must start the swing for the outside pitch because the hips can't supply power that early in the swing.
> > While Jack may not have talked about it in the terms I've used here, he means the same thing - there is enough power in the partial hip turn (and add in some extra top hand torque) to release the bat from the shoulder turn early in the swing and drive the outside pitch to the opposite field gap with power and without pulling off the ball.
> > Saat does not think that this power exists and so must be supplied by hands and arms only. Saat - correct me if I misunderstand you here, I don't mean to twist your words.
> > I think many of us have seen clips of Manny Ramirez crushing outside pitches to right center using this technique so we've seen it in action. Its not just theory.
> > Saat, your thoughts on this?

> I have seen many of the clips out there and I agree there are many hitters who hit the outside pitch as you describe . Sosa comes to mind & I have a clip of Griffey Jr that would probably be an excellent advertisement for your views. However, I have seen just as many clips of hitters hitting the outside pitch as I have described. I gues the question is, which way is more efficient. I believe the so-called "linear" method is better than the "rotational" method, because it supplies just as much power to the opposite field but has more margin for error. That additional margin for error makes a huge difference in how often the ball will be driven to the opposite field as a line drive vs. how often the ball will be mishit & be a grounder >to the pull side or even missed entirely.

If Sosa, Ramirez, Griffey Jr are rotational hitters with opposite field power, who are the linear hitters with opposite field power who equal these guys.?
I have great respect for the Gwynn's, Boggs', Carew's, etc. who use more linear techniques to create high percentage hitting. I never considered them power hitters. And that type of hitter typically shows an inability to pull the inside pitch for power - they are always looking away and pushing the ball to an opening.
If I had to make a broad statement (meaning there may be exceptions) I think the 'linear' types I described have a harder time hitting the inside pitch for power than the rotational guys we mentioned have hitting the outside pitch for power.
Where things get muddy is the quasi-rotational hitters - guys who can turn on an inside pitch for power but don't know how to turn on an outside pitch to hit it the other way. Ron Gant, Jim Rice, John Valentin, Juan Gonzalez, etc. They are excellent examples of the failure of 'pull hitters' to hit the other way. And they ground out to SS on outside pitches, as you say.
This style of 'hooking' the outside pitch gives rotational guys a bad name. These players lose their rotation or disconnect from it and reach for the outside pitch, hitting the outside of the ball weakly. I suspect they are turning both the hips and shoulders too far and casting early to reach the ball (turning past the ball); or they are not using their hips much at all and trying to shoulder and wrist the ball. They are classic examples of not staying inside the ball, but not classic examples of true rotational hitters.
What Jack describes is not this last type of hitter.
