The Washington Nationals traded 1B Nick Johnson to the Florida Marlins for minor league left-handed starter Aaron Thompson, according to multiple sources.
Sources also confirmed that the Nats sent left-handed reliever Joe Beimel to the Colorado Rockies for two minor league players, as yet undisclosed.
Johnson, a free agent after this season, hit .294/.408/402 with six home runs and 63 RBIs this season for the Nats, in his sixth season with the organization.
He was the last player to wear the tri-colors of the Montreal Expos in the organization.
Thompson, 22, is 5-9 with a 4.11 ERA with Double-A Jacksonville. He was a first-round pick for the Marlins in 2005, out of high school in Texas. He was the 13th-ranked Florida prospect, according to Baseball America.
According to one scouting service, Thompson has a 87-90 MPH fastball and plus slider to go along with pinpoint command.
Beimel spends less than one season with the Nats. He was 1-5 with a 3.40 ERA and one save in 45 appearances.
