Josh Rojas also had three RBI for Arizona, which moved ahead of Los Angeles for the NL West lead soon after the game when the Dodgers blew a late lead at Cincinnati. The Diamondbacks have won seven of nine to improve to 36-25.
“We just chipped away,” Arizona manager Torey Lovullo said after his team trailed 4-1 after one inning. “That was my mindset. It was still early. We had a chance to play catch-up if we did what we did best with controlling the zone and trying to get guys on base.”
Washington entered the day with the worst bullpen ERA in the National League at 4.73, and Arizona took full advantage when starter Jake Irvin was pulled after hitting Corbin Carroll to open the fifth inning.
Reliever Erasmo Ramírez (2-3) plunked Christian Walker with his first pitch, committed a balk to move over both runners and walked Emmanuel Rivera to load the bases. Arizona sandwiched a pair of sacrifice flies around Gabriel Moreno’s RBI single to make it 6-4.
Ramírez has allowed runs in five of his last six outings, and his ERA has jumped from 4.03 to 6.33 in that span.
Rojas added a two-run single in the sixth, and Smith swatted a two-run shot to left-center in the seventh as the Diamondbacks expanded their lead against Chad Kuhl.
Arizona drew eight walks, including five in five innings against the Nationals' bullpen.
“The walks are going to kill us every time,” Washington manager Dave Martinez said. “We have to start pounding the strike zone again.”
José Ruiz (2-1) pitched 1 2/3 scoreless innings for the victory.
Garrett’s grand slam in the first off Arizona starter Tommy Henry gave Washington a 4-1 lead. The Diamondbacks got two back in the fourth when Moreno and Smith had RBI singles off Irvin, who allowed four runs in four-plus innings.
“I knew we just had to hang around long enough for the offense to score some runs,” said Henry, who allowed five runs in 4 1/3 innings. “You put up a 10-spot, you're going to win a lot of games when you do that.”
Diamondbacks: OF Lourdes Gurriel Jr. was out of the lineup for the second game in a row with right groin tightness.
