The Washington Nationals have a pretty good front three of the starting rotation. Stephen Strasburg, Gio Gonzalez and Jordan Zimmermann have been accountable to put up innings and get guys out. Strasburg has had an injury and Gio an off year but Zim is coming off his best season in the majors. What else do the Nats need? Well, they need a back end starter that can finish out the rotation. Mike Rizzo and the front office have some options, it all depends on how much money they want to spend. Here are some of the starters I believe have a chance of wearing a Nats uni next season.
