They have divergent histories against tonight’s Marlins starter, Chris Volstad. Zimmerman has crushed him, going 13 for 21 with two homers and two doubles. Werth has been abysmal, going 1 for 20 with seven strikeouts and no walks. Maybe Zimmerman can give him some tips.

The other thing the Nationals can be happy about is their starting pitching, particularly the number of walks issued. Nationals starters have allowed four walks through 23 1/3 innings, the fifth-best rate in the majors.

Tonight, Livan Hernandez will become the first Nationals starter to make his second start. As always, talk about the game right here.
