They probably figure with Goodwin that, when he's right, he is clearly the 4th OF, and if he gets hurt, they can DL him and add Severino, De Aza, Stevenson, etc... As for the batting eye, they probably have seen enough in the instructional league and practice this week to think he can walk in and hit. Simple swing, good discipline. It let's them use Robles to pinch run if behind or as a defensive replacement if ahead.
