See, I'd have no objection to his playing LF or even 3B if he's going to be an .800 - .850 guy. I've always been a 'solid up the middle' guy and willing to sacrifice a little defense at the corner positions to get the power if necessary. That's where I think we are with Hanley. I don't see any GG's in Hanley's future but he can be a hitting machine. If Moncado can be Hanley at the other corner I'll live with his defense, assuming it's no worse than Shaw's. And realistically, if Moncado's defense is as good as Travis Shaw's, Moncado would be an upgrade at 3B.
WARNING. BLASPHEMY AHEAD!
- And furthermore, if Moncado can play LF reasonably well I wouldn't object to making Beni the centerpiece in a trade for a #1/#2 pitcher.
However, I wouldn't want to make that switch without seeing Moncado out there first. I'm not a fan of a player's learning on the fly!
