In his final year in the minors he hit .301/.318/.416
The overall slash numbers are pulled down by the first 2 years in the low minors.
This is a man who carried his career in the minors with his glove, and seems to have figured out a swing that's worked consistently for him over the last 2+ years off the bench. That's actually harder in principle than doing the same thing while starting every day. You realize that right?
In other words, when he was pure AAAA, it was because he wasn't hitting, and now he's putting up a full win above replacement last year with his bat as a bench player in the bigs. If you want to be skeptical about that, fine, but I hope you're signing the same tune with Iggy, because it's the same thing.
I don't want the situation we have to devolve until Ciriaco is starting every day because it would mean that some talented players were on the shelf or gone, but if we had to do it, I have no doubt at all that Ciriaco could be well above replacement level as a full time starting shortstop.
