WASHINGTON -- Because the second game of a doubleheader against the Dodgers was rained out on Thursday, left-hander Ross Detwiler was pushed back in the Nationals' rotation, and will now pitch on Monday against the Mets at Citi Field in New York.

Manager Davey Johnson said he didn't want to push back any of his other starters -- such as Tom Milone and Stephen Strasburg, who were scheduled for Friday and Sunday outings, respectively.

In the meantime. Detwiler will work out of the bullpen for a short period, and pitch on eight days' rest against New York.

Wang would like to return to Nationals

WASHINGTON -- Right-hander Chien-Ming Wang is a free agent after this season, and said through an interpreter that he would like to return to the Nationals next season.

Wang said he feels loyalty toward the team because it took care of him when he had shoulder problems the last two years. He also said money will not be an issue.

"They have taken care of me a lot the past two years. So I want to come back," said Wang, who is making $1 million this season. "I want to help them get more wins. I just want to get back, no matter the salary."

Wang continues to make progress since returning from his shoulder woes. Entering Friday's action against the Astros, Wang has appeared in eight games, and is 2-3 with a 4.43 ERA.

In his last start, Wang received a no-decision and allowed four runs in six innings. If he comes back to Washington for the 2012 season, Wang most likely will be the third starter in the rotation, behind right-handers Stephen Strasburg and Jordan Zimmermann.

Nats set Strasburg's upcoming schedule

WASHINGTON -- After he pitches on Sunday against the Astros, Nationals right-hander Stephen Strasburg will pitch on five days' rest, which means he will face the Marlins a week from Saturday at Nationals Park, according to manager Davey Johnson. His next start after that will be Sept. 23 against the Braves.

Johnson has not ruled out Strasburg pitching the last day of the season against the Marlins on Sept. 28 in Miami.

Johnson also said that the team hasn't dismissed the possibility of Strasburg playing in the instructional league this fall.

Bernadina remains out of Nationals' lineup

WASHINGTON -- Outfielder Roger Bernadina was out of the Nationals' lineup again on Friday night.

Manager Davey Johnson said Bernadina can pinch-run and play defense, but can't grip a bat because he hurt his left hand diving for a ball against the Mets last Saturday.

Johnson said he expects Bernadina to be back in the lineup in the next few days.
