Lineup remains the same, Zimmermann available in relief

The Nationals' lineup will remain the same for today's must-win Game 4 of the best-of-five National League Division Series. Davey Johnson will not make tweaks to his batting order today, despite Danny Espinosa's struggles and the offense's recent issues driving in runs. "Going right with what we had yesterday," Johnson said. "Going to have a little better outcome." Jordan Zimmermann will be available in relief today if Ross Detwiler falters or is unable to work deep into the game. Today will serve as Zimmermann's throw day, and since he threw just 63 pitches in Game 2, he should have plenty in the tank today if he's needed. Johnson said there isn't exactly a gameplan for a situation in which your starter doesn't pitch well in a must-win game, but he did acknowledge that he might have to manage a little differently, given the circumstances today. "We're in a situation that if Det has a problem, I would go to Zim earlier," Johnson said.
