I sometimes stumble across some very interesting baseball sites by accident at times while wasting my life away on the 'net! Not that ANY of you are guilty of this also!
I saw this website below on Twitter today and was curious enough to click on it to see what it was about. At first glance I thought it had to do with pitching and ball rotation. However, it is actually about teaching and/or training batters to learn how to have quicker and more reliable "pitch" recognition out of the Pitcher's hand. Can it work? I don't know. I suppose you'll have to find that out for yourself. But I figured I would post the website link below if you're interested in the concept.
