Nationals Finalize 25-man roster

My starting rotation preview is below, so just scroll down to take a look. One player in the rotation will not be listed on the 25-man roster to start the season (Jordan Zimmermann) because of free agency/arbitration reasons. The Nationals will have to send someone down (or cut someone) on April 19th, Zimmermann's first start. The roster is below, or found here:

Pitching Rotation
LHP John Lannan
LHP Scott Olsen
RHP Daniel Cabrera
RHP Shairon Martis

Infielders
Ronnie Belliard
Alberto Gonzalez
Cristian Guzman
Willie Harris
Nick Johnson
Ryan Zimmerman

Bullpen
LHP Joe Beimel
RHP Joel Hanrahan
LHP Mike Hinckley
LHP Wil Ledezma
RHP Saul Rivera
RHP Steven Shell
RHP Julian Tavarez

Outfielders
Elijah Dukes
Adam Dunn
Austin Kearns
Lastings Milledge
Josh Willingham

Catchers
Josh Bard
Jesus Flores
Wil Nieves

On the 19th, either Bard or Nieves will be sent down to make room for Zimmermann. When Anderson Hernandez (the projected starting second baseman) comes back in a week, expect Alberto Gonzalez to be sent down.
