On Urias' milb.com page, there were a few articles about his defense (including comments from him stating that the was working on his SS defense), so I'd assume its more of a known issue. Maybe its MLB passible, but not what Arcia is capable of doing. His 2018 MLB prospect ranking seems to sum it well: Urias proved plenty capable at shortstop in 2017, first in Double-A and then in the Arizona Fall League, and should continue to see some time there moving forward. His ultimate defensive home, however, is likely second base, where he profiles as an above-average defender with good range and arm strength. Overall, Urias has the ingredients to hit atop a lineup while manning a middle-infield position for a long, long time. So odd thought... if we were going for Lindor, what if Huira was the bait and Urias is slated for 2B?
