PHOENIX — Randal Grichuk hit a three-run homer in Arizona's eight-run second inning, Brandon Pfaadt struck out 10 and the Diamondbacks routed the Los Angeles Dodgers 14-3 on Sunday.
The Dodgers won the series' first two games by jumping on Arizona early.
The Diamondbacks returned the favor in bashing fashion on Sunday, sending 11 batters to the plate against Justin Wrobleski (1-2) in the second inning.
''The first two games didn't go our way, but we didn't give up in either of those games and we're not going to give up — that showed up today,'' Grichuk said. ''Guys are firing on all cylinders, and it's fun to come out and get it done.''
Eugenio Suárez homered and had two RBIs, and Geraldo Perdomo hit a two-run double in Arizona's big inning. Pfaadt (9-7) was solid after being staked to the big early lead, helping Arizona move back within five games of the Dodgers in the NL West.
The Diamondbacks had 17 hits to end the Dodgers' four-game winning streak. Los Angeles closed out the game with infielder Kiké Hernández pitching the eighth inning.
''We got put into a tough spot today, then you're just trying to find a way to salvage pitching,'' Dodgers manager Dave Roberts said. ''I think the positive is we're back to full strength for tomorrow with a chance to win the series.''
Wrobleski was added to the roster as a September callup to give the rotation an extra day of rest following Clayton Kershaw's trip to the injured list with a bone spur in his big left toe.
