    UZR vs Positioning

    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.
