I play college baseball and am taught by probably one of the only instructors in america who actually knows how to teach the swing correctly...your swing mechanics are way off....I knew about 99% of coaches did not have a clue what they were talking about; but for you to post this as the most comprehensive swing analysis on the web is just terrible....rotation is probably the worst thing that can be in a swing a it forces a hitter "off line" ....i think i am going to write a book on hitting so no more nonsense can be sold to people....email me if you are interested once this happens....if it does....but trust me, reading this sort of stuff really makes me want to write one....
