LOS ANGELES (AP) — Paul Goldschmidt homered in the first inning for the second straight game, Miguel Montero added a three-run shot and rookie Wade Miley pitched eight dominant innings for the Arizona Diamondbacks in an 8-2 victory over the Los Angeles Dodgers on Tuesday night.

Miley (12-6) allowed three hits, struck out seven and walked one. The only run against the left-hander was a first-inning homer by Mark Ellis, who came in 6-for-11 against him.

Chris Capuano (10-7) allowed five runs, six hits and three walks in six innings with six strikeouts. The left-hander is 1-4 with a 4.66 ERA in his last five starts — a stretch that began with a 7-1 loss at Arizona on July 8.

The Dodgers’ loss, coupled with San Francisco’s 4-1 win over the Mets, dropped Los Angeles behind the NL West-leading Giants while the Diamondbacks remained 3 1-2 games off the pace.
