Jordan Zimmermann takes the mound, the results of which, at this point, have become almost a given for the Nationals. He is aiming for his 13th win of the season, which would tie him with Max Scherzer of the Detroit Tigers for the major league lead. Jason Marquis makes his first start in Washington since he was traded in 2011. The lineups are here. As always, talk about the game here.
