To me, Arcia is projecting like an elite hitter by the time he's 25, as he's holding his own in his short time so far at AA at age 21. The walks will come - Span wasn't walking much when he was at the same stage either. I don't have the L/R splits to go by but I have to believe he can overcome a deficiency if one is there - wishful thinking on my part, so I'm saying I'd go with my coaches and scouts on whatever they say about that. I know you're talking about which minor leaguer to package up, but the comparison I did to Span just confirms to me that Span is the one to trade for a AA pitcher with potential, if you're willing to trade Arcia for that. Cover Span's absence with stopgaps like Revere or even Mastro until Hicks/Arcia are ready, in 2014, say. Span's a table-setter, as are Revere and Mastro, and too many of those put your roster out of whack. In the long run, I think we'll look back at Span as a capable but very average CFer.
