Well, contrart to what cwebb said, your outfield may not look as great for the next month, now that Ramirez is out. If you can still front a decent outfield, (I doubt it, but is Kearns still on the waiver wire?) this would be a no brainer. Two top 15 drafted starting pitchers? Even if Brown goes down, I have no worries about Hudson. You have to give to get, and you shouldn't miss Herges at all.
Ordonez is great, but you're getting quality back.
