The Nationals spent the winter adding to their pitching staff, trading for Gio Gonzalez and signing Edwin Jackson to fill out a rotation that features homegrown studs Stephen Strasburg and Jordan Zimmermann. There's a lot of talent there, but it's not exactly a stable of horses. Gonzalez pitched into the seventh inning in just 19 of 32 starts last year; Jackson did so in 16 of 31. Strasburg and Zimmermann are easing back in after elbow injuries and aren't likely to work deep into games. The Nats have a crowded bullpen, though, so manager Davey Johnson should make a virtue out of necessity and keep all five of his starters (John Lannan is the last) on a short leash. With Drew Storen as closer, Tyler Clippard a multi-inning setup man, Tom Gorzelanny a converted lefty starter who might be the next Sean Marshall and hard-throwing righty Henry Rodriguez, the Nationals have a bullpen deep enough to back up a six-innings-and-out rotation. Until the team is completely comfortable with Strasburg and Zimmermann taking on a 220-inning load, they can get value from them at 160--180 innings while winning games with what has been a strength over the last two years.
