There's little or no ambiguity in MLB.com's Bill Ladson's latest "Inbox: Nats inspiring confidence", where he writes that it's hard to make predictions about how successful the Nationals will be in twenty-ten, "...because Rizzo is not finished trying to build the Nationals for 2010. I know they're trying to trade for a top-of-the-rotation starter." Still trying, huh? Who could the DC GM be targeting?
