WASHINGTON -- While he is not close to an extension, first baseman Adam Dunn said the Nationals and his agent, Greg Genske, talked while the team was in Houston playing a four-game series against the Astros last week.

According to Dunn, the talks were cordial, but both sides didn't bring up dollar figures. Dunn reiterated that he wants to stay in Washington, where he has become a popular figure because of his power and patience at the plate. Entering Wednesday's action, Dunn was hitting .280 with 11 home runs, 30 RBIs and 30 walks. He added his 12th homer with a two-run shot in the first inning.

"The Nationals know how I feel about this place. I hope that something can be worked out," Dunn said. "Again, I'm not in any hurry. It's probably No. 10 on my list of things to worry about."

Dunn anoints Strasburg as Nats' staff ace

WASHINGTON -- Nationals first baseman Adam Dunn said it's not a stretch to call right-hander Stephen Strasburg the ace of the Nationals' pitching staff.

Strasburg made his Major League debut on Tuesday, pitching seven innings, allowing two runs on four hits and striking out 14 batters in a 5-2 victory against the Pirates at Nationals Park.

"I don't think it's weird to call [Strasburg the ace of the staff]," Dunn said. "He is obviously our top pitcher right now. I don't think that's taking away from anything anyone has done here this year. Guys like him come around once every 10, 15, 20 years."

Nationals' injury report

WASHINGTON -- Nationals left-hander Scott Olsen had a minor setback recently. After having two bullpen sessions, Olsen went to play catch and acknowledged that he was feeling discomfort in his left shoulder. The team had to shut him down for most of this week, but Olsen said he will play catch during the off day in Detroit on Monday.

Olsen has been on the disabled list since May 22 because of shoulder tightness. Manager Jim Riggleman doesn't know when Olsen will pitch in a Major League game.

In other news, catcher Jesus Flores, who is on the DL because of an ailing right shoulder, continues to make progress. According to general manager Mike Rizzo, Flores is playing simulated games where he is hitting live pitching and throwing to second base. Rizzo declined to say when Flores will play in a Major League game.
