Meanwhile, when the Nationals travel to Baltimore for the final two games of the four-game, home-and-home series, they'll face the opposite situation as the Orioles with the ability to start an extra hitter.
Manager Matt Williams said there are a number of possibilities for those two games at Camden Yards on Wednesday and Thursday regarding his lineup as well as players getting rest. Williams said Ryan Zimmerman, Jayson Werth or Adam LaRoche could all get days off in Baltimore. In the case that LaRoche sits, Williams said Zimmerman would move to first base, where he's started once this season.
"We have to look at the next couple of days and how we come out of it," Williams said. "We'll just have to see how it goes in the next couple [games]."
