LOS ANGELES—Christian Walker hit a go-ahead home run in the fourth inning and a three-run blast in the ninth—his 16th and 17th career shots at Dodger Stadium—and the Arizona Diamondbacks overcame a rough start to throttle Los Angeles 12–4 on Wednesday night.
Gabriel Moreno and Lourdes Gurriel Jr. added two-run homers for Arizona, which found itself down 4–1 before Diamondbacks starter Cristian Mena retired a batter in his major-league debut.
