If you are up 2-0, Game 3 is a chance to drop the hammer, given the frequency (one in 135) with which 3-0 edges are blown. If you are down 0-2, it is the call to avoid that 0-3 fate. And if it is a 1-1 draw, it is for the advantage. So the Giants are in a good place, with Matt Cain set to take the ball Wednesday in St. Louis.
