To my eye he looks plus but not plus-plus defensively. I don't know exactly how that translates to WAR and no idea how accurate my scouting is.
And about now is when Chris will want to chime in that the Orioles at least don't think the publicly available defensive metrics are worth much . So we may not even be talking in units that really have any truth behind them even if the general idea is something we're familiar with.
Just with DRS and UZR. The Statcast numbers make sense to look at imo.
Plus vs. Plus Plus... his lack of arm strength would factor there.
