LOS ANGELES -- 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). 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.
The Dodgers and D-Backs made separate deals in the waning hours preceding Tuesday's nonroster trading deadline. Los Angeles sent reliever Josh Lindblom to Philadelphia for Shane Victorino, who will be the Dodgers' regular left fielder and leadoff hitter. Arizona acquired outfielder Scott Podsednik and reliever Matt Albers from Boston for reliever Craig Breslow. Victorino won a World Series ring with the Phillies in 2008, and Podsednik got one with the 2005 Chicago White Sox.
Goldschmidt, whose three-run homer Monday night against Aaron Harang ignited a 7-2 Diamondbacks victory, drove Capuano's 1-2 pitch into the lower seats in the left field corner for his 15th of the season after a two-out walk to Jason Kubel. It was Goldschmidt's sixth hit in his first eight career at-bats against the left-hander.
Capuano returned to the dugout after the inning and slammed his glove against the wall before taking a seat -- but he was back on his feet moments later congratulating Ellis on his one-out solo homer.
The Diamondbacks' first three hits all were by Goldschmidt. Justin Upton, the subject of numerous trade rumors on Tuesday, followed Goldschmidt's two-out single in the sixth with a single and Montero made it 5-1 with a towering drive into the bullpen in right on a 2-0 count -- one pitch after Capuano got a visit from pitching coach Rick Honeycutt.
Arizona tacked on three runs in the ninth when Chris Young scored on Upton's fielder's choice grounder and Chris Johnson hit a two-run single with the bases loaded. Johnson had a grand slam in Monday night in his Diamondbacks debut after coming over in a trade from Houston, and is 4-for-8 with his new club.
Notes: Dodgers C Matt Treanor went 0-for-2 with a walk while his wife, Misty May Treanor, was half a world away preparing for her next beach volleyball match at the London Olympics on Wednesday. She is vying for her third Olympic gold medal. ... The D-Backs are 14-1 this season when Goldschmidt homers. Before this series, only one of his 21 previous big league home runs came in the first inning. ... Capuano is 3-10 with five no-decisions when he has given up a homer in the opening inning. ... When Victorino makes his Dodgers debut on Wednesday afternoon against D-Backs' Triple-A call-up Patrick Corbine will become the eighth player manager Don Mattingly will have used in the leadoff spot this season, and the ninth to start in left. ... Miley, inserted into the rotation on April 23 after RHP Daniel Hudson went on the DL with an impingement in his shoulder, hasn't walked more than two batters in any of his last 19 starts -- one behind Cincinnati's Bronson Arroyo for the longest active streak in the majors.
