As the old cliché goes, this is a good problem to have. Yankee fans are talking about heads needing to roll and pissed about things like us getting Whitlock. We're talking about whether to promote a guy who looks like a possible star.
I heartily disagree that there's nothing to lose. What if he stinks for 5 games and we lose 3 or 4 of them? And then what do you do with him?

Arroyo is on the IL right now, otherwise he would be at 2B.
If Arroyo is 100% healthy, there's no full-time spot for Duran.
If Arroyo is not healthy, boom, there's your opening for Duran (as Kike would play mostly 2B).
