I agree that a fast runner "typically" scores on a double there, but at the same time you can't be a 17ing idiot as a 3rd base coach and just say, "well, the 2nd baseman has it, and Demarcus is about to hit third, but hell the percentages say he'll score", and then send him. You have to judge it case by case, and Yastremzski cut that ball off...it wasn't your typical gapper.
