Update 12:35 ET: According to Ken Rosenthal and John Paul Morosi of FOXSports.com, the Marlins have upped their offer for Nick Johnson, and have now included another minor leaguer to go along with Class-AAA right-hander Ryan Tucker.
According to ESPN's Peter Gammons the Marlins are getting close to acquiring Nationals first baseman Nick Johnson.
We reported yesterday that the Marlins were making a "strong push" for Johnson, and as early as this morning it was reported that Johnson was the Marlins top target.
As Gammons notes the Nationals were content on letting their players test the free agent market, and receive compensation picks, but because Johnson has missed so many games with injuries it's likely he wouldn't qualify for any sort of compensation.
