I highly doubt there exists no evidence that supports the inference that getting a runner over to third from second with nobody out (one out after the bunt) increases a team's chance of scoring the runner that was on second. No Sully is correct. I don't know the exact numbers but the chances of scoreing with a runner on first and no outs is higher than scoreing a run with a runner on second and one out. Outs are precious and should be treated as such. That wasn't my scenario though. What about a runner on second with nobody out vs. a runner on third with one out? A team is likely to score more runs when a runner is on second with no outs than with a runner on third with one out: http://www.tangotiger.net/RE9902.html That's not hypothetical. The numbers come from actual games played between 1999-2002. In most situations a sac bunt is a dumb idea, and bunting Pierre to third is no exception. Again, I'm not sure that is enough information. I am talking about the situation where you are trying to get one run. Like, a tie game in the bottom of the ninth. Which alternative is more likely to get that one run? I am fully aware that if you take an out away from the inning, you are less likely to score a bunch of runs. I can't copy and paste the article for copyright reasons, but there's a study on that here: http://www.baseballprospectus.com/article.php?articleid=2869 The conclusion: "We can say that sacrificing is a good idea when pitchers are batting and, for most of the hitters in the league, when there is a man on second, no one out, and a single run is the goal." If the Cubs are playing for one run in the bottom of the 9th and the opposing team's closer on the mound, bunting Pierre to third is probably not a bad idea. Doing it in the first or third inning, as Dusty so likes to do, is a bad idea.
