Nick Ahmed then laid down a bunt to try to move the runners up a base, and Washington pitcher Aaron Barrett threw the ball down the first-base line, allowing two runs to score and Ahmed to make it all the way to third.
Pinch-hitter Jarrod Saltalamacchia followed with another bloop hit to score Ahmed, and later in the inning Aaron Hill drew a bases-loaded walk to cap the scoring and give the D-backs a 5-2 lead.
"Just pesky," D-backs manager Chip Hale said of his team.
