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 think the only acceptable time to use that bunt is in a close game when you're trying to push across ONE run.
