MLB.com's Bill Ladson is reporting that the Nationals are entering the mix for free agent right-hander Chien-Ming Wang. Wang is also drawing interest from the Dodgers, but they are having internal discussions about whether or not Wang can be effective. 

Dodgers officials told MLB.com that Wang is at least three months away from being ready, which puts his return date right around the middle of April or early May. For the Dodgers, adding a two-time 19 game winner to their rotation would pay huge dividends if he can stay healthy. 

Sources say that the Mets, Cardinals, and Pirates, among others, are tracking Wang to some degree.
