This summer I went to a Braves game while I was down in Atlanta. Our seats were in the upper deck behind home plate. My seat had an excellent view of the LHH in the box. I believe that you always stand in the back of the box when you are hitting. I will not get into all the reasons why Coaches tell hitters to stand up in the box but the number one reason hitters move up is because the pitcher throws too slow. If the pitcher throws slow, don't move up in the box, just adjust your timing and start later. You want the pitcher to have to throw the ball as far as possible. When you stand in the back of the box, the pitcher's job is harder because the catcher has to move far enough back to avoid your bat. The pitcher has to throw the ball the distance to the catchers glove and your eyes use the length of flight of the ball to determine the swing the body needs on that pitch.
