The death of the incomparable Stephen Hawking inspires us to reach for analogies from physics, even though we know even less about the subject than we do about, say, restoring antiques or Masters curling. Bear with us for another two paragraphs and we’ll get to the stuff you’re here for.
Thus: It seems to us that baseball stats can be divided and subdivided into particles. Blender stats like WAR, Win Shares, and our new Fangraphs colleague Jay Jaffe’s JAWS can be seen as molecules. In the right hands, these numbers are interesting and illuminating. But they are useless for our present purpose, which is to identify players who might do better than the Fantasy market expects them to.
These molecules are made up of atoms: the often-Fantasy-relevant outcome stats (ERA, Batting Average, and so on) that comprise the statistical lingua franca of baseball, known and (usually) acknowledged as meaningful by both stat geeks and non-geek fans. Hadrons, in this scheme, are the kinds of stats that reflect the things that most immediately produce the on-field events on which the outcome stats depend: hard-hit balls, “zone swings,” fly-ball distance, and so on. And at the quark level you find the stats that make up the hadrons, and that nobody could even measure until recently: barrels, tunnels, spin rate, things that we’ve probably never heard of.
