All of the focus of the Nationals off-season and what is left to do has been on Adam LaRoche, and while signing him or not signing him will have the biggest impact on the team moving forward the Nationals do have another need. In 2012 the Washington Nationals bullpen ranked fourteenth in baseball with 3.3 fWAR. There is some question as to how effective a stat like WAR is in measuring relievers as it heavily weights innings pitched. By all measures the Nationals had better relievers than the Rockies, but because the Rockies relievers pitched so many more innings than the rest of baseball they finished second in fWAR.
By the rate state of ERA the Nationals had the seventh best bullpen in the majors and by FIP the twelfth. Moving forward into 2013 there are questions about the Nationals bullpen. Gone from last year's squad are Sean Burnett, Tom Gorzelanny, and Mike Gonzalez. While Gorzelanny or Gonzalez could be brought back to join Zach Duke as the lefties in the pen, that is unlikely. The Nationals have been tied heavily to JP Howell but until a deal happens nothing can be assumed. As it stands right now the Nationals bullpen lines up with Storen, Clippard, Stammen, Duke, Mattheus, Bray, and Henry Rodriguez.
