Prince isn't an average fielder, you made the claim "nearly average", which really isn't supportable with any metric other than UZR, and And That already laid out why your logic is faulty. If you want to use UZR definitive proof of anything you're being disingenuous at best, no single defensive or offensive metric is definitive proof of anything. Those scoops he fails to convert into outs, don't count against him, they count against the other IFs in UZR, but they should, because of those scoops are plays that any competent 1B makes. I'm not even going to get into the little things like footwork, never tossing the ball to the covering pitcher, saving the extra base on a bad throw, and the like which won't show up in metrics either. As for Yuni only being a slight downgrade from Escobar, that's not an accurate statement either. Escobar is young enough he was likely to improve and he has really hit his stride defensively this season, while Yuni is clearly terrible. He does an adequate job fielding the balls he can get to, and that's about all one can say positive about him. Through yesterday using UZR which you are so fond of Escobar is 6 runs positive and Yuni is over 4 runs negative on the year. How is that a slight downgrade? I stick by assertion that measuring fielding by any single metric is flawed and that one needs to take all data into account. I think in the case of 1B because so many things are unaccounted for by other metrics, that Plus/Minus is the best metric to use because each play at 1B is being individually watched and graded. Prince clearly makes every other IF worse because his scoop percentage is horrible, something that no metric is going to adequately account for. Simply put his defense is so bad he makes the entire IF worse which in turn hurts the pitching because the pitchers have to throw more pitches. He's better than he was, but that's not really saying much given how poor he was when he came up. He's also a much better athlete than people give him credit for, which makes his poor play all the more frustrating for me personally.
