Dunn hopes extension gets settled soon

Nationals first baseman says there's no deadline for deal

WASHINGTON -- Nationals first baseman Adam Dunn reiterated Sunday that there isn't a deadline when it comes to getting a contract extension, but acknowledged he would like to get something done so he doesn't have to hear his name in trade rumors.

As of Sunday, Dunn doesn't know how the negotiations are going. He instructed his agent, Greg Genske, not to tell him anything until progress is made.

Dunn is coming off one of his best seasons, hitting .267 with 38 home runs and 105 RBIs.

"I would like to have some serious talks soon. If not, we have a long offseason [to get something done]," Dunn said. "I don't have a time line. [But] I don't want this thing lingering on until July. But things are going good, as far as negotiations. It's not going to affect me one way or the other. I look at it as a trade deadline thing. I don't want every single day [someone asking how the negotiations are going]. I don't want that to happen."

Playing baseball isn't the only reason Dunn wants to stay with the Nationals. He believes the team is on the rise, and loves living in the nation's capital and viewing the historical scenery around the city.

"This team is going in the right direction, and I'm all for it," Dunn said. "There are a lot of things to be excited about. I feel comfortable here. I think I fit in really well here. My family loves it here. It seems like a great fit. When we do something special here, I want to be part of it.

"I like the historical stuff. You are not going to find anything like that in the world. It's awesome. It's a cool city. I wish I had more time to spend here to visit all that stuff. It's nice."

Detwiler, Flores, Wang, Coste on DL

WASHINGTON -- The Nationals placed left-hander Ross Detwiler (right hip surgery), catcher Jesus Flores (right shoulder surgery) and right-hander Chien-Ming Wang (right shoulder surgery) on the 60-day disabled list, while catcher Chris Coste was placed on the 15-day DL because of a right elbow strain.

Coste hurt the elbow during practice before the Nationals faced the Cardinals in Jupiter, Fla., on Wednesday. Once he is healthy, Coste is expected to play often for Triple-A Syracuse.

As far as Detwiler and Wang are concerned, they are slated to pitch in games by June 1. Detwiler is currently playing catch, while Wang is having bullpen sessions.

General manager Mike Rizzo said Flores has started his throwing program and could be back on the field within four to six weeks, provided there aren't any setbacks.

Rizzo gives explanation on Olsen, Mock

WASHINGTON -- Nationals general manager Mike Rizzo indicated that left-hander Scott Olsen is still building up arm strength, and the team needed to find out if right-hander Garrett Mock has the stuff to pitch in the big leagues.

Olsen had shoulder surgery last summer, and the team wants him to improve his velocity on his fastball and breaking pitches.

"The good thing with Olsen is that he is pain free and his arm is loose and free," Rizzo said. "We feel with time, he will build more arm strength."

Based on the Spring Training stats, Olsen outpitched Mock, but the numbers appear to be an afterthought when it comes to Mock.

"Mock [got off to a quick] start in the spring, but faded a little bit at the end, but we felt that his upside is to the point where we made the choice at this time," Rizzo said.

Nationals sending Chico to Harrisburg

WASHINGTON -- With Scott Olsen starting the season with Triple-A Syracuse, left-hander Matt Chico will be going to Double-A Harrisburg after missing the last 10 days because of the flu. Chico still needs to build up strength before he can start the season.
