Re: Re: Re: drop & tilt before rotation?


Posted by: tom.guerry (tom.guerry@kp.org) on Fri Feb 28 08:25:46 2003


I was reading on another site a discussion about rotational mechanics and it was said that "the upper body stays back as the elbows drops into the slot" and another poster made reference to Epstein's number drills and esp. #2 drop and tilt occurs as front heel drops and BEFORE shoulder rotation.

It looks like to me that Bonds, A-Rod, Garciapora (3 I watched) start rotating the shoulders and slotting the elbows at the SAME time - I do agree that the bat turns 1st (THT as Jack calls it) before shoulder rotation and there is a certain elbow movement that occurs with that. But aside from turning the bat or THT, why would you "drop and tilt" before shoulder rotation - that to me puts you in a very weak hitting position? If you are connected the right way (and that is a big IF)- then why not just rotate? What does dropping and tilting (or Epstein's #2) accomplish when done BEFORE the shoulders start to rotate? Is drop and tilt another cue or the same thing as THT? This does not make sense to me - I do not understand how or what benefit that has. I probably do not understand what the CUE "drop and tilt" is or means. Does anybody know?

A key to good separation is the external rotation of the front thigh and how this supports the hip.The actual position of the foot is secondary and can vary.Sometimes you teach backward by accentuating a foot position that will encourage good upper leg positioning and relation to the hip.I prefer the front foot at least at 45 degrees because I prefer some stride.I think its hard to cock the hip,strecth the body and separate without the hands and stride moving more freely together,but "no-stride" certainly works.When you do no stride,the front foot tends to be more closed,although in Nomar you will notice the heel down position will vary with inside out location(NOT and argument for using foot position/angle as a cue-it's something that will happen,like back toe drag,as another example-these are REACTIVE motions that are not "good teaches",they are "no teaches",or if mentioned,"bad teaches").
