"With Chien-Ming Wang in the fold, the Nationals have a commodity all teams pine for: starting pitching depth. In Mike Rizzo's eyes, the Nationals have "eight or nine" starting pitchers who could join their rotation at some point in 2012, and some pitchers who could pitch in the majors will spend the majority of their year in the minor leagues.

After Wang's signing became official today, the Nationals control the 2012 contract rights to eight pitchers who started for them in the majors in 2012: Stephen Strasburg, Jordan Zimmermann, John Lannan, Ross Detwiler, Brad Peacock, Tom Milone, Tom Gorzelanny and Wang.

"I really like the way the rotation is set right now," Rizzo said. "We have great depth there. We have great talent. We have some top-of-the-rotation guys. We have some middle-of-the-rotation guys. We have some back-of-the-rotation guys. We've got great depth in our minor league system. We've got guys that probably should be pitching in the big leagues this season and may not be. I think that's a tribute to where we're at.

"With that said, we're certainly not satisfied ever. You can never have enough quality starting pitching. It hasn't changed our long-term offseason outlook that we'd like to improve our starting rotation.""
