The Royals traded outfielder Gregor Blanco to the Washington Nationals today in exchange for a player to be named later. The 28-year old Blanco was acquired from Atlanta last July in a trade-deadline deal for outfielder Rick Ankiel. Blanco spent the remainder of the 2010 season with the Royals, posting a .274 batting average in 49 games, but was beat out for a big-league outfield job in spring training by Jarrod Dyson and Mitch Maier.
