> > I am more and more interested in how players go about setting up their axis at launch/maintain axis until contact.Bonds talks about the importance of getting the body in the right position for a given pitch.When he misses one,he says he can mentally see where his body needed to be and the next time he sees that pitch he nails it.Often he gets it right the first time.He never forgets a pitch.Even started hitting the submariner in Colorado.

> It's impossible to make all your timing adjustments with separation and many only adjust the hands or swing. Making bigger adjustments, hitting off the front leg (foot), or hitting of the back foot more is all part of hitting. As long as your hands do not betray you, your in good shape.
>
> For the most part I think the hitter should strive for leverage when the torso kicks in, less drag and more back foot pop. Everyone is different, although you can only lift the back heel so much before all your weight goes forward.
>
> Sosa goes from low to high, gets way up for the high stuff. More drag, less weight on the back leg. Anyone who starts out sitting, has to get up and drag some on the high stuff. That guy can really swing from his 'butt'!
>
> I understand what your saying. If a hitter is looking outside and uses more top hand torque their back foot can also drag and kick sideways.
>
> I saw Bonds hitting the slinger. He does the same thing Edgar does on a sidearm slinger, change their posture and swings even more level (matching the plane of a flatter pitch). Most hitters try to take the same approach. In fastpitch the curve is similar to a slinger and gets the same results when hitters try to swing down through the plane of the pitch.
>
> Bonds handles almost everything with posture (IMO). Almost lining up his top hand with the ball. What's his cue?, trying to punch the ball, well he's usually in a good position. The one thing I do not like is Bonds almost drops straight down.
>
> What's with the toe tap? On his 63rd he barely moved before swinging (slower pitcher with only 1 strike). When does he change, counts, two strikes, slower pitchers. I've seen plenty change their stride according to what their anticipating.
>
> We'll have to discuss this reactve torque in greater detail. I have more to say on this. I'm currently working on 3D animations (learning curve), someday in the future Jack is going to replace those hand
rawings of Sosa, Griffey.

>the longer this discussion goes the more fascinating it becomes......but back to my initial question, "Is it the knee/back foot that pushes the hips or is it the hips that pull the pivot foot?".......i kind of thought that the knee/foot sort of followed the hips....what do you think?"......is the consensus that the back foot is simply reacting to hip turn, etc & that there is no active driving of the back leg?........it seems like tim olson somewhere articulated a convincing argument to the contrary but i could be wrong....respectfully, grc.....
