Well, I will say I was thinking Hutch was older than 24, but even then we have some guys like McAllister, Marcum and pretty soon House and Tomlin will all be options when they return from the DL. And Cody Anderson has been pretty good since getting the call up as well.
Antonetti usually only makes trades if we are getting a MLB ready player in return. The Gomes trade is an example of that. On top of that, our worse overall position player is Bourn and we need a replacement for him. That's where Pompey comes into play. I'd imagine with Frazier and Zimmer making good progress, at the very least Antonetti would want Pompey and a starter vs Pompey and Alford (another OF prospect). Deep down though, I think Alford is going to be an amazing player.
Edit: I forgot to add that I also would be interested in Pentecost if he can play 1B as well. After all, we just signed that six year extension with Gomes and Carlos Santana isn't living up to the hype nor is he going to be on the team in a couple years.
