I understand what you mean about A-Gon in right. He has done well overall all. But your injury concern is spot on. Especially the hammy issue. As we all know, he has no speed. I do admire him for doing it though.
So I see your point with the urgency of trading Youk sooner than later.
Edit: But with Interleague play, it's the only way to keep he and Papi in the line up. We do have 6 more games in NL parks.
