Washington acquired Harris from Atlanta on Monday in exchange for Ehire Adrianza.
Adrianza, a journeyman utility player on an expiring deal, wasn't a long-term fit for the rebuilding Nationals, who opted to cash him out for a prospect in Harris. As a 26-year-old who has yet to reach the Triple-A level, Harris wouldn't seem to have much developmental upside, but he'll at least strengthen the Nationals' outfield depth in the upper levels of their farm system. Harris was hitting .233/.333/.317 with two home runs and four stolen bases in 220 plate appearances for Double-A Mississippi this season.
Harris will join the Braves' major-league spring training camp.
Harris has only played 41 games at the Double-A level, so he's likely a season away from pushing for a big-league spot. In 131 games at the Low-A, High-A and Double-A levels last season, the outfielder slashed .323/.389/.498.
