One of Kevin Long's works in progress that epitomizes the hard work that goes into hitting.  During the 2009 Playoffs, Nick Swisher struggled big time.  He worked with Kevin between games and got Swisher to square up his body in relation to the pitcher. Nick got hot and helped the Yankees to their 27th World Championship.

Here you see the hands in tight to the body, back knee turning inward, the head still, top hand up, bottom hand down. I will try to find a picture of his stance prior to the swing to show being square.
