Excellent article by Yirsandy Rodriguez here on TalkSox, see right hand column for access ........
It addresses why the Sox batters, as a whole, are in a true power slump and not just in a group of individual slumps. This smacks of organizational direction or influence to emphasize contact, but not hard contact.
You have to do two things as a hitter, hit the ball and hit it with high exit velocity. Of course, to hit it you have to see it and judge the pitches trajectory , so there's that too.
