Did they say he's an unprofessional hitter or anything even close?
No doubt, he's unorthodox, and I would not argue against calling him a big undisciplined, but the kid walks enough to show he's not a hack. He hits so much, it's not a fluke, and I'm not sure trying to mess with his approach is such a good idea.
To me, it helps a team having a variety of hitting approaches in the line-up.
