Yeah, basically this, that Westburg's underlying numbers (EV, barrel %, xwOBA) seem to point at this being pretty real, or at least that there's nothing 'undeserved / lucky' about this hot streak, if it's just that.
The problem with a Cowser/Kjerstad/Stowers/Bradfield outfield roster is there are no right handers to handle LHP.
I don't think and completely left handed outfield is the destination for an organization the values versatility.
