It's a high BABIP in comparison to his half season in Baltimore as a reliever, it's not a crazy departure from his time as a starter, and I think that's the concern. Is his half season in Baltimore indicative of who he is, or are we seeing a guy drifting back down to Earth?
You're right, the number of runners allowed has been atrocious, and while we can take some solace in his zero percentage, that''ll start to reflect his poor WHIP given enough time.
