I keep reading how good Vargas is defensively. He has a bounce throw to first base, because he can't consistently hit the first baseman in the chest. Sosa is even worse. Niether is going to the minors. Niether is going to ride the bench. Niether is going to suddenly be able to consistently field third or first. One or both will have to eventually go. Montgomery is the future third baseman. Get what you can for one of them now, and the other later.
