UZR is Ultimate Zone Rating in runs above average (Arm+DPR+RngR+ErrR). So four items combined ARm, Double Play, Range and Error rating. I think the range rating takes into account how far the OF moves to make plays. This season our four OF range ratings (by position) are as follows: Rasmus -11 (was +14.6 LY), Gose +2.3, Bautista -0.5, Cabrerra -4.7 (-6.8 LY) so I think that is consistent with my "eye test". I hope a healthy Rasmus can come back with a return to LY fielding ability.
