I know I may be solo on this one, but if we really want Hernandez on the 25 man roster, I'd see what we could get for Holt.
In no way would I hand him away, and I would not trade him for lesser value, but Hernandez is a better fielding SS, maybe even at 2b and 3B. Trading Holt would put our OF depth in peril, but with Selsky looking good, we might be okay.
I still think, as much as I like Hernandez, he should start the season in AAA.
