WASHINGTON -- Nationals general manager Mike Rizzo said he doesn't know if Bryce Harper will play in the playoffs for Double-A Harrisburg.

Harper is still on the seven-day disabled list because of a right hamstring strain. Rizzo said Harper is not going to play until he is 100 percent.

If he doesn't play in the postseason, Harper is expected to play in the Arizona Fall League.

The first overall pick in the 2010 First-Year Player Draft, Harper had a great first season in professional baseball, hitting .297 with 17 homers and 58 RBIs for Harrisburg and Class A Hagerstown.

After long recovery, Flores finally feeling good

WASHINGTON -- Nationals catcher Jesus Flores is showing signs of being the productive player he was before injuring his shoulder on a foul tip hit off the bat of D-Backs center fielder Chris Young in May 2009. Flores ended up missing almost two years because of the shoulder injury.

On Saturday against the Mets, Flores had his best game of the season, going 3-for-4, driving in a run in an 8-7 victory.

"Flo had a good game. He is really starting to come back around to what he did a couple of years ago before he was hurt," third baseman Ryan Zimmerman said. "It's good to see Flo do that kind of stuff."

Before the shoulder injury, Flores was having his best season in '09, hitting .301 with four home runs and 15 RBIs.

Flores feels like he is the player he once was. The difference now is, he's a backup.

"I feel 100 percent back to where I want to be -- defensively, offensively," Flores said. "Baseball has a lot of ups and downs. I just need to make the adjustments, be patient, be positive. It's going to be better the next day."

Harris possible addition to bench next year

WASHINGTON -- The Nationals have had an unproductive bench this season, going 31-for-165 (.187) with two home runs and 11 RBIs entering Sunday's action against the Mets.

Improving the bench would be one of Washington's top priorities this season.

Might the Nationals consider bringing Mets outfielder Willie Harris back into the fold next year? Harris, a free agent after this season, can play every position except first base, catcher and pitcher.

Harris, who was a popular figure in Washington, is hitting .245 with a home run and 17 RBIs for the Mets. With the Nats, Harris was a productive hitter off the bench. Last year, Harris drove in 32 runs in 224 at-bats.

Harris wasn't available Sunday to discuss his feelings about the Nationals or Mets.
