Momentum.
It’s the thing that the people who we call “nerds” in baseball still cannot quantify. All the plays that happen, all the balls and strikes, all the minutiae that goes into a baseball game can seemingly be put into some kind of supercomputer to be studied, analyzed and be used in application elsewhere, but momentum? That’s the elusive part of baseball that we still cannot put a number on.
Yet for those who have watched the game for many, many moons, momentum is pretty clearly defined.
It’s in the way that pitchers are able to dot the corners of the strikezone with relative ease.
