Dodgers can't stop Christian Walker, D-Backs slugger hits 2 homers in 12-4 rout at Dodger Stadium

Christian Walker hit a tiebreaking home run in the fourth inning and a three-run home run in the ninth — his 16th and 17th career hits at Dodger Stadium — and the Arizona Diamondbacks overcame a rough start to beat Los Angeles 12-4 on Wednesday night.

Gabriel Moreno and Lourdes Gurriel Jr. added two-run homers for Arizona, which trailed 4-1, before Diamondbacks starter Cristian Mena struck out a batter in his major league debut.

Freddie Freeman and Teoscar Hernández hit back-to-back home runs in the first inning for the National League West-leading Dodgers. After four of their first five hitters had hits, they managed just two more the rest of the game. Arizona had 16 hits.

Walker went 4 for 5, narrowly missing the cycle, with four RBIs and three runs. With two outs in the fourth, he sent a 3-2 pitch from Ryan Yarbrough (3-2) to left for a 5-4 lead. Walker hit his 20th home run of the season in the ninth inning, a two-out shot off Michael Petersen.

Bryce Jarvis (1-2) got the win in relief.

Arizona’s offense was led mostly by players in the bottom of the lineup. Eugenio Suarez, Moreno and Geraldo Perdomo had seven hits, including Moreno’s home run in the third inning.

The Dodgers’ only hits after the first inning were a double by Miguel Rojas in the sixth inning and a single by Freeman in the eighth inning.

Mena allowed a single, a walk, back-to-back home runs and a single to the first five Dodgers. The 21-year-old right-hander struck out two and walked three in three innings.

Dodgers rookie Gavin Stone allowed four runs and seven hits in three innings, requiring 49 pitches in the first two innings. He struck out three batters and walked three.
