“This being said a pitcher starts in a lateral position as he drives towards his full stride. A right handed pitcher triple extends with his right leg which is pushing his right hip around to the right side. Also after front foot strike his right shoulder and right arm follow the path of his right hip.”

 

OK, maybe this is where I'm getting off track.  I thought the right hip (for RH) fires straight to the target in a straight line and not 'around to the right side'. 

Should I just let this go and just concentrate on 3X and force vector?

Because the hips must rotate around its axis, the right hip rotates off to the right. The shoulders do the same. You started a great thread here but yes we are way down this rabbit hole so we can start heading back.

for a goof, my son did some pitching yesterday and had me radar gun him to see where he is.  he is 12 1/2 and threw 65-69mph consistently.  towards the end he was reaching for that extra couple of mph and started “trying things”.  as he tried stuff, i called out the speed of the pitch.  most of the stuff he tried was more of a “feel” than a real mechanical change, but one of the things he tried was landing on the line or slightly open to it.  the result?  loss of speed.  when he landed slightly open, he was at 61mph.  the only benefit was that he ended up in a better fielding position a little quicker than normal…not by much though.  

to me, it looks like he lands more closed when he concentrates on getting more separation,  which gives him the best velocity.  i really don't care if it's “right”, i care about the results.  if he throws harder and has some control…i guess it's all good.Wink

Fellas:

Let me give you all some info. on the body's center of gravity as it was defined to me

                                   “The human body's centre of gravity”

The point at which the whole weight of an object can be considered to act and, therefore , at which all parts of an object are in balance.

The position of the centre of gravity varies according to the shape of the object, In objects with a regular shape the center of gravity coincides with it's geometric center, In objects with an irregular and variable shape (As in the human body) the centre of gravity cannot be defined easily and changes with every change in position of the body; it may not lie within the physical substances of the body. body movements may raise or lower the body parts around the centre of gravity, in this way it is possible to jump different heights even though the centre of gravity reaches the same height. it was also explained to me that the centre of gravity is deep in the center of the body behind the belly button.

It is acceptable to land your stride foot 5 to 10 degrees on either side of your stride line without being considered as either throwing across your body or opening up too much.

 As in any sport when one gets the feet close together inside the shoulders one's body tends to become out of balance, if and when the stride foot and leg lands directly in line with the hips and body while in it's sideways body position to touch down one's body also tends to become out of balance unless the landing foot is slanted/angled slightly across not parallel to the stride line, and as Brent mentioned it is acceptable to stride towards your target when it is just slightly off center, Zedoryu you hit this one right on the head.

Be very careful about copying major leaguers so as not to copy their faults also this is where all of those uneducated, conventional, opinionated people make their worst mistakes.

The website pro pitching institue dot com has some insight (right or wrong) on where and why the front foot should land where it does.  Not promoting the website, just another opinion.

 

Thanks again Brent, I love this site!  I feel like a rebel questioning the authority/opinions/science of the pitching world!  Feels good 🙂
