A critique of WAR

141 Comments

No, not war. WAR. As in, Wins Above Replacement level.  Hippeaux at IIATMS has a lengthy column up today looking at the stat (it’s actually multiple stats complied via different methodologies by different folks) and pointing out a potential flaw. Specifically, that one of its components — the defensive metric, Ultimate Zone Rating or UZR — that Hippeaux argues distorts WAR.

I am quite obviously not a stats guy, so I can’t say that I have any real insight here. I’m mostly waiting to watch the arguments and counterarguments to the piece, which is how most folks who don’t have their own aptitude with this stuff should probably proceed. Over time you get some clarity as to whether the critique makes sense, if the counterarguments make sense, etc., and then eventually you get something approaching an advancement in real knowledge.  Kind of like science, you know.

But this article is getting a lot of play this morning, pro and con, so it’s worth throwing out there.

One warning: I’ve already seen a couple of decidedly non-statty writers link to this thing and say something to the effect of “see, those holier-than-thou stats types don’t know WHAT they’re talking about.”  To those people I offer a hearty “shove it.”  A critique of a component of an analytical tool does not constitute a repudiation of the analytical tool any more than a faulty component in your engine constitutes a totaled car.  If it makes you feel better to say “see, those statheads aren’t God,” so be it. But do know that the statheads have never been interested in being God. They just want to understand stuff, and this sort of intellectual give and take is how that occurs.

Bad news for the Cubs’ Yu Darvish: The right-hander is headed back to the disabled list with right triceps tendinitis, the team announced Saturday. It’s the second such assignment for Darvish this season, but the first time he’s been sidelined with arm issues. Neither the severity of his injury nor a concrete timeframe for his recovery has been revealed yet, but the move is retroactive to May 23 and will allow him to come off the DL by June 2, assuming all goes well.

Prior to the injury, Darvish went 1-3 in eight starts with a 4.95 ERA, 4.7 BB/9 and 11.0 SO/9 through 40 innings. Needless to say, these aren’t the kind of results the Cubs were hoping to see after inking the righty to a six-year, $126 million contract back in February, though the circumstances affecting his performances appear to have largely been out of his control. He missed a start in early May after coming down with the flu and has struggled to pitch beyond the fifth inning in five of his eight starts to date.

The Cubs recalled left-hander Randy Rosario from Triple-A Iowa in a corresponding move. Rosario has yet to amass more than five career innings in the majors, but has impressed at Triple-A so far this year: he maintained an 0.97 ERA, 2.8 BB/9 and 6.1 SO/9 through 19 1/3 innings in 2018. As for Darvish’s next scheduled turn in the rotation, Tyler Chatwood is lined up to take the mound when the Cubs face off against the Giants in the series finale on Sunday. A starter for Monday night’s game has yet to be determined.
