MLB network had a good video on bunting yesterday. My takeaway was: men on 1st and 2nd, no out? Bunting might be good. Otherwise? Bunting is probably a bad idea. Before watching the video I thought bunting was almost always a bad idea (unless the batter had a really good chance of getting on with a bunt), so it was good to see there's still a time for it even if it's a sacrifice bunt.
