Christian Walker continued to torment his division rival with two more home runs, and Gabriel Moreno and Lourdes Gurriel Jr. also went deep as the visiting Arizona Diamondbacks rolled to a 12-4 road victory over the Los Angeles Dodgers on Wednesday.

Walker now has seven home runs in eight games against the Dodgers this season as the Diamondbacks rallied from a three-run deficit in the first inning. Walker had four hits, including a double and three runs scored.

Arizona right-hander Cristian Mena gave up four runs after four batters of his major league debut, but Diamondbacks pitching did not allow another run.

Freddie Freeman and Teoscar Hernandez hit back-to-back home runs in the first inning as the Dodgers fell to 2-3 against Arizona at home this season. Dodgers starter Gavin Stone, who had a 1.62 ERA over his past six starts, gave up four runs on seven hits and three walks in three innings, striking out three.

The Diamondbacks took a 1-0 lead in the first inning, loading the bases with one out but getting only a sacrifice fly from Gurriel.

Freeman hit a three-run home run as Los Angeles’ third batter of the game and Hernandez followed with a solo shot for a 4-1 lead.

As Mena settled down, the Diamondbacks got even with two outs in the third inning. Eugenio Suarez had an RBI double and Moreno hit a two-run home run to tie the score.

Mena gave up four runs on four hits over three innings with three walks and two strikeouts.

Arizona took a 5-4 lead in the fourth inning on Walker’s first home run of the game against Ryan Yarbrough (3-2).

Geraldo Perdomo bunted in a run for the Diamondbacks in the fifth. Gurriel hit a two-run home run in the sixth and Suarez added an RBI double in the eighth for a 9-4 lead. Walker added a three-run homer in the ninth, his 20th this season.

Bryce Jarvis (1-2) did not allow a run over 2 1/3 innings for Arizona.
