He may have changed his approach, but the fact is he just isn't seeing the ball. He has had plenty of good pitches to hit this year.
Lets be honest, this guy has done little to nothing going on year 3. Sure he rebounded a little last year but still ended up with a pitiful average and was still a boat anchor on the lineup. There has to be a organizational component to this...above average players seem to come to the White Sox and immediately start sucking. There are countless examples.
