Marquis is coming off one of his best seasons, going 15-13 with a 4.04 ERA with the Rockies. He also represented Colorado in the All-Star Game.
During his 10-year career in the Major Leagues -- which has included stints with the Braves, Cardinals, Cubs and Rockies -- Marquis has won 94 games with a 4.48 ERA.
Marquis said he can be one person who can help Washington's young pitching staff, which includes John Lannan and Garrett Mock. Marquis indicated that he can teach the young kids what he learned from veterans like Tom Glavine, Greg Maddux, Chris Carpenter and Matt Morris.
In fact, Marquis felt he was a mentor to Rockies pitchers Jorge De La Rosa and Ubaldo Jimenez.
"Learning from those veterans, learning how to win and recognizing situations, I felt I brought that to the table in Colorado and I really helped ... De La Rosa and Jimenez, who were trying to get over that hump," said Marquis. "I feel I could bring that [kind of leadership] to a team."
Published reports have surfaced that Marquis, who is a New York native, wants to play for the Mets, but he said he wants to play for a team that makes him feel wanted.
"I want to play for a team that is headed in the right direction and making the moves that is necessary to get themselves back to being a winning organization," Marquis said. "Some of the moves the Nationals have made -- like [signing Stephen Strasburg] signing Pudge [Ivan Rodriguez] and getting [Brian Bruney] -- they are making the necessary steps. I feel I can fit right in and bring a winning attitude to the team. Every where I've been, I've won. I feel it's not a coincidence. I want to help a team get over the hump."
