Yeah that's the problem, first the bunt has to be successful (questionable since HoJo whiffed on his first attempt) and then the same stuff has to happen subsequently. I remember Scully going on assuming that the A-B-C progression was a sure thing and therefore Davey's strategy cost them the game and therefore the series. Maybe, but hardly a sure thing; hitters pop-up bunts, K trying to bunt, bunt into force plays, bunt into double plays, etc. all the time. Mookie Had bunted the previous play which would have been a force out at 2nd but for a Rich Gedman high throw/error. I suspect Davey figured that, had he left the 21 y/o rookie call-up who was 5 for 30 in his ML career to that point in to hit, it's a sure signal to Boston that it's bunt all the way and he at least wanted the option of making their defense guess and/or taking it off after one strike.
