Washington Nationals vs Milwaukee Brewers: Series Preview w/ Brew Crew Ball.

Over the next four days the Washington Nationals will throw Edwin Jackson, Ross Detwiler, Jordan Zimmermann and Gio Gonzalez at the Milwaukee Brewers, who counter with Yovani Gallardo, Mike Fiers, Randy Wolf and Zack Greinke. The Nationals are riding a five-game winning-streak and they just got back-to-back strong outings from Gio and Stephen Strasburg in the three-game sweep of the New York Mets on the road in Citi Field. The Nats are in Milwaukee's Miller Park tonight. We talked to the SB Nation's Brewers site Brew Crew Ball about the upcoming series:

Brew Crew Ball: Coming into Wednesday the Nationals had four starters (Jordan Zimmermann, Gio Gonzalez, Stephen Strasburg and Ross Detwiler) with ERAs at or under 3.13. Is pitching the reason this team has been successful?

Federal Baseball: Absolutely. Pitching and defense, because the offense has only really come together recently as the Nats got Ryan Zimmerman back and back to full-strength, got Michael Morse off the DL and got Danny Espinosa on the way to getting turned around from the left side. Ian Desmond has carried the offense to some extent, especially after they moved him to the six-hole. Desmond settled in batting sixth and has a .320/.361/.522 line since Davey Johnson moved him there for good. But the starting pitchers have the NL's lowest ERA (3.11), lowest FIP (3.32), second-lowest xFIP (3.57), highest fWAR (+11.9), second-highest K/9 (8.15) and third-lowest HR/9 (0.76). They've been dominant. Strasburg and Gio obviously and Jordan Zimmermann quietly, and E-Jax and Ross Detwiler at 4-5 have been strong too.
