Garcia went 3-for-4 with a walk and a run scored in Tuesday's 8-5 win over Atlanta.
The rookie paced a 17-hit barrage by the Nats, and he drew his first big-league walk for good measure. Garcia's MLB career is off to a flying start, as he's gone 6-for-17 through four games since being added to the roster. The 20-year-old has a chance to lock down the starting spot at second base with Starlin Castro (wrist) likely out for the rest of the regular season.
