How do scouts, coaches, et. al. evaluate hitting? Obviously, we have all posted about ball exit speed which is an easily obtained numerical measurement. But what about batting practice evaluations? If it is BP style pitching (or I have even seen front toss), it is generally really easy to hit with less than good swings. I have seen players knock the crap out of the ball in BP, only to have trouble getting it past the pitcher when facing live, get the hitter out, pitching. Assuming the swing is too fast for the naked eye to see, how can they possibly know what they are looking at? What are they looking for?
