A source confirmed that the Nationals are in Buehrle's hometown of St. Charles, Mo., in an all-out effort to convince the veteran to pitch in the nation's capitol next season and beyond.
It is a far different tactic than the one the Nationals' division rival took earlier this month. The Florida Marlins tried to woo Buehrle by showing him South Beach and the club's new stadium set to open in 2012.
The Nationals are expected to be aggressive in trying to lure a veteran pitcher to lead their rotation, which will be bolstered by the full-time return of Stephen Strasburg, who is on the way back from Tommy John surgery.
Buehrle has become one of the most sought after free-agent pitchers on the market thanks to his consistency and durability. He is the only pitcher in baseball to post double-digit victories, pitch at least 200 innings and make 30 starts in each of the last 11 seasons.
Aside from the Marlins and Nationals, Buehrle has also drawn interest from the New York Yankees, Boston Red Sox and Texas Rangers. White Sox general manager Kenny Williams said he hasn't ruled out Buehrle's return to the South Side but it won't be easy with all of the interest from clubs with deep pockets.
