UZR vs Positioning

[amjgt]

How does UZR take into account superior defensive positioning?

 

Ibanez's catch of Escobar's potential double, in the 6th inning, made me think about this. Dick was saying what a good catch it was for a 42yo. And it was certainly out of his "zone," but the catch was 100% due to good positioning. So does Ibanez get credit for a "out of zone" catch or does UZR account for this?

From what I remember, UZR uses a very, very simplistic method of accounting for shifts. If the defense is deemed to be in a shift, the play is ignored (or something like that). When deemed not to be in a shift, defenders assumed to be in standard/typical defensive zone.

He gets credit for a catch made in a zone that doesn't see a lot of catches and because many balls are simple routine catches and the weighting involved on those that are not. His UZR will become untrustworthy like almost everybody else's.
