I'm going to have to say hmmmmm on those estimates, but I'm just taking a WAG on that myself. I think the defense fails to make the play far more often. (20%+) At the younger ages, far more often. But even at the college level. Haven't watched much D1 (just some of what is on TV), but even there I see crazy things happen on bunts all the time. At the D3 level which I have watched quite a bit of the last 2 years, I see defensive disasters happen what seems like quite often. ( I may be guilty of remembering the disasters and forgetting the routine.) I see lot's of big innings result from small ball early on that morphs into a frustrated defense and lot's of baserunners. I guess my point is if one is going to play the percentages, they should know what the percentages are.
It can be hard to track, especially just from the scorebook. If the defense fails to make the play and it results in a hit, was it a great bunt or poor defense? Book probably won't say.
I quite agree that playing the percentages should be the way to go. Apparently that has been totally embraced in MLB, seems like managers don't scratch their behind without consutling the numbers these days. Conversly, I know of a coach who will bunt no matter what with a runner on first, I think it's just been imprinted on the brain.
Best move is to think it through as to when and why.
Regarding giving up the out on a 1st-3rd steal, if your catcher is 10% at throwing out runners and 20% at having the ball end up in CF, do you throw down? :lmao: Been there done that......
