I totally understand infielddad...its not easy..go look at this pic of manny...in order for him to get the bat in the hitting zone, the back shoulder will slightly dip...now the bat is goin down because he's holding up high...once it gets in the hitting zone, it will be flat...as he makes contact with the ball, it will be slightly heading up(part of the letter "U" i talked about)and thats why they finish high. Getting the barrel too far out in front of your hand too early or hitting around the baseball will cause top spin. Remember, good pitchers are trying to change planes with the baseball so as a hitter we have to get on that plane in order to hit the ball solid. If the hitter swings down (thats one plane) and the pitcher in throwing down (thats same plane as hitter) they would have to meet the perfect point in that plane to even make contact..and if you make contact, its like slicing a golf ball...
hope this made sense to you...let me know
