I proably shouldn't comment either but I like the per centages.
Man on second and no outs:
If you hit here are your possibilities. A long ball to deep center or right, the runner advances. A hit, the runner might score. A home run. A walk and you've got two men on.
If you bunt, usually the best that will happen is one out and the runner advances. It usually still takes a hit to get him in. If the batter misses the ball, the runner gets caught off base for the out and you've given up your advantage. Unless it's a pitcher with an under 200 batting ave. or a super speedster that bunts for hits, I'm with Jack. Go for it.
What will really make you sick is what happened to me the other night. Extra innings and I've got the home team. My lead-off man doubles with a decent hitter following him. The hitter misses a bunt attempt and the runner is out at third. On the next pitch the hitter gets a double but I go on to lose on a home run that should never have been. I most cases, I would rather see the per centage plays.
