Coaches, please keep in mind the importance of outs when calling for a sacrifice bunt. And other than the very few, very rare situations in a game that I've outlined, DON'T BUNT.
That's what the facts say. 2+2=4. That's it.
I rarely disagree with J H - and honestly I offer this less as disagreement than clarification - but I think it is overstating the case for not sac bunting based on run expectancies to imply that this is "fact" or something that is mathematically precise.
First, these charts assume an average batter facing an average pitcher - something that rarely, if ever, occurs. Every team is full of better hitters, and lesser hitters, and to complicate matters more, guys who have speed, or are adept at hitting behind the runner, or spectacularly good (or bad) at bunting...and rarely do all these things add up to point in a single decision-making direction. Even if you assume an "average" pitcher, is he tired, or fresh? Is he on that day, or struggling? And, as many of the coaches in this thread explained very well (I'm thinking particularly of Coach May's post, but I know that there were several others who made excellent and similar observations), there are many other coaching reasons you might want to sacrifice, as well, because you value the intangible benefit of doing so more than the "average" runs you "lose" (I use quotes because, again, the result is binary and the average run "expectancy" is in no way a guarantee).
There are so many factors that a coach has to mentally "adjust" for in making a bunt/swing away decision that, IMO, even at the MLB level, the most you can say about these run expectancies is that (a) they should be strongly considered, and (b) if you choose to go against it, you should have good and strong reasons for ignoring what is generally true in these situations - the out is more valuable than the base advancement, with some exceptions in close and late situations.
Secondly, if you look at the comments to Beyond the Boxscore link I previously posted (as well as some of the comments to the link J H posted, above), you will see that one of the authors of The Book (the originators of these run expectancy tables), "MGL" or Mitchel Lichtman, explains why simply referring to the RE charts does not necessarily dictate the decision making behind swinging away or sac bunting in the way it would appear you can and maybe even should. The charts are only a start, and there are many other factors to consider: how often do you bunt and things other than an out and a base advancement occur? How does a consistently infrequent bunting team change the way the defense approaches these situations, and what subtle differences in the "average" run expectancies would you expect that to produce? How often does a particular batter/bunter beat out a sac bunt just because he is an excellent bunter? Or, on the other hand, what are the chances of a particular bunter/batter popping up a bunt, or bunting into a double play, or otherwise failing to execute? What are the chances of a ROE against a particular team with a particular batter? For better or worse, no matter what side of this debate you are on, you can't just assume one out and a one-base advance, particularly as you move to lower levels of baseball.
Which brings me to the last point, which has been the subject of a pretty great discussion here: what applies in MLB doesn't necessarily apply in the minors, or in college, or in HS baseball. Higher run environments, less power/SLG, more variability of talent throughout a league or a line-up - all these things can change the "equation" pretty dramatically.
All things considered, it is rarely a yes/no answer to the "should you bunt?" question. Maybe on the extremes. Everything else is debatable.
Josh, I hope you felt that was a fair criticism / clarification of the valid point you made....
