I said he can play CF in a pinch, he's no longer an infielder, though. Those numbers from Happ are LF, with OAA Happ is -1 at LF... Springer is +1 at CF, fairly big discrepancy. I'd love Happ on this team, sign me up, but they need to take care of the pen first and foremost.
ETA: I'm not a big fan of defensive numbers, they seem to fluctuate far too much for me. LTBF is never right
