WASHINGTON -- Nationals team president Stan Kasten denied reports on Wednesday that he is unhappy and wants to leave the organization.

Reports from the Washington Times and other media outlets indicated that the Lerner group was not listening to Kasten's advice on improving the franchise, but Kasten said he plans to stick with the Nationals and see them become championship contenders.

"I have no plans to leave at all," Kasten said. "I came here committed to making this a championship franchise. I continue to be optimistic that we are going to get it all done here.

"We have had bumps and bruises. We've had some hurdles and some challenges. But we have accomplished a great deal in the two years. My plan is to stay here."

Kasten also said he gets along with the Lerner group. Kasten acknowledged debate on certain issues, but would not discuss those with the media.

"I think there have been wild exaggerations, but overall, we continue to be on the right track," Kasten said. "I absolutely get along with the Lerners. We discuss everything vigorously, debate it and work through things. My relationship with every member of the family has been outstanding."

Kasten joined the Nationals in 2006 as team president and a founding partner.
