The Nationals and Phillies have been rained out and will make up today’s game during a split doubleheader in Philadelphia on Sept. 20. The teams have a shared off day Monday, but both sides preferred to wait to play until September, when expanded rosters will ensure the pitching staffs will not be worn down.

For now, the Nationals plan to stick with their current rotation and simply move them back, Manager Davey Johnson said, which means Chien-Ming Wang will pitch Tuesday on six days of rest. Wang had one extra day of rest before his last start because of a rain postponement, and he redeemed two uneven starts by taking a no-hitter into the sixth inning in a win against the Cubs.

“He had his best outing for us with an extra day,” Johnson said. “After how he worked to make it back here, the extra couple days rest is going to be good for him.”

Wang will not be on a strict pitch count and “he could throw 100 pitches,” Johnson said. But Johnson will also make the judgment based on how the game goes and how Wang is feeling.

With the rainout and Monday’s scheduled off day, the Nationals will have consecutive days without baseball. Johnson was not concerned about gathering rust.

“This time of year, it’s useful,” Johnson said. “Everybody could use a couple days off. This way, we get a little bus ride back to D.C., get there early, have dinner with the family.”
