WASHINGTON -

Gio Gonzalez threw six crisp innings to lead the Washington Nationals to a 5-0 victory over the Miami Marlins on Tuesday night.

Gonzalez allowed three singles and two walks. He allowed one baserunner to get as far as second, and struck out five hitters.

Gonzalez retired his last 10 batters and is 2-0 with a 0.75 ERA.

Adam LaRoche had three hits and drove in a run off Henderson Alvarez (0-2). Anthony Rendon went 2 for 4 with three RBIs as Washington improved to 5-2.

Miami entered an NL-best 5-2, a year after finishing with a league-high 100 losses. Led by Giancarlo Stanton, the Marlins were averaging a majors-best six runs a game, but they couldn't solve Gonzalez or four relievers.
