Guru,
Who is your MLB friend? Please name your source. I would like to review tape or still pics of your friend. This is a constant debate between coaches with different backgrounds. Most lower level softball coaches seem to subscribe to the rotational method , where most pro baseball coaches concentrate on a short linear approach. Back to the video & pictures. As they say, a picture says a thousand words. If you have a link or any photos to post, please post with a description of the photo. I have many photos to trade if you are interested.
I do not think it is necessary to name names. And no I do not want to exchange pictures with you. That just sounds creepy.
The big league coaches may teach to have a smaller swing because those guys are much stronger than my daughter. She needs to create torque to get power, they do not. They are big strong men.
