I got this from Mlb4u.com, and I think they got it from Buster Olney.

"Cristian Guzman, SS--Washington Nationals: The Cubs could pursue a trade for him if they fail to sign Kaz Matsui.

It seems like Hendry and Piniella think it's very important to have a lefthanded hitter who can play second and short with some speed. Honestly I would rather they sign Matsui, because I still think he has some upside, if he could ever stay healthy. Cristian Guzman is a faster verison of Neifi Perez. The Cubs must not think OBP is a important for a bench player/spot starter in the infield. Being a lefthanded hitter with speed seems to be what their after. If were gonna make a trade with the Nationals for lefthanded middle infielder, I would rather the Cubs try to trade for Felipe Lopez. But he would probably cost alot more talent in return then Guzman.(who the Nationals should be willing to dump for nothing)
