In this situation, it's not that bad of an idea. He's facing a pitcher with very good control that could afford to walk the previous hitter to get to Dempster. He's not going to want to fall behind Dempster, so the first pitch might be the best one he would see. If I'm Dempster, I treat that situation like a 3-1 count...look for a fastball in a specific spot, and if I get it, take a hard swing at it. All that said, I'm listening on radio, so I didn't see the pitch he swung at. It was ball 1 and one he couldn't have done anything with. In that case, he shouldn't have hacked at it. However, I don't think that situation warranted an automatic take on the first pitch. He can't hit. I would rather he take 3 pitches and make the pitcher work.
