LOS ANGELES (AP) Scott Van Slyke has bounced between the Dodgers and the minors five times this season, even smiling whenever manager Don Mattingly approached him with the news that he would be going back down again.
Van Slyke had his teammates grinning with a pinch-hit two-run homer in the bottom of the 11th inning that gave the Dodgers a 5-3 win over the Arizona Diamondbacks on Tuesday night.
``It's been my goal the whole year just to contribute,'' he said, having been called up from Triple-A Albuquerque on Sept. 1.
Van Slyke found himself in a celebratory dog pile after triggering the Dodgers' seventh walk-off win of the season. As he rounded the bases, he knew what awaited him.
``I'm about to get my jersey torn off,'' he said of the team's ritual.
Van Slyke lined the homer off Josh Collmenter (4-3) into the lower left field seats, scoring Mark Ellis who singled just ahead of Van Slyke.
``I was just looking for something to hit hard,'' Van Slyke said. ``It was a good changeup down.''
It was the Dodgers' fifth consecutive win over the D-backs. Los Angeles reduced its magic number in the NL West race to six, and leads the division by 13 games over Arizona with 18 to play.
``Everybody is excited about it,'' Van Slyke said. ``We're on a roll and we want to continue winning games. I think our attitude will continue to be the same after we clinch.''
Los Angeles hit six homers, including three by Juan Uribe, in winning the series opener on Monday.
Chris Withrow (3-0) got the victory, striking out four in 1 1-3 innings. The bullpen allowed just one hit in five scoreless innings.
Collmenter gave up two runs and three hits.
The Dodgers had the go-ahead run on third with two outs in the 10th.
Adrian Gonzalez singled and was replaced by pinch-runner Dee Gordon, who stole second. Andre Ethier was intentionally walked before Collmenter uncorked a wild pitch, allowing Gordon to take third. Ethier moved up to second when the ball sailed to the backstop. Juan Uribe struck out swinging to end the threat a night after he homered three times.
After Arizona took a 3-2 lead in the top of the fifth, the Dodgers tied the game in the bottom of the inning on Ethier's RBI double that scored Hanley Ramirez, who walked with two outs.
``They've got a good team, from their lineup to their pitching,'' Arizona starter Trevor Cahill said. ``There's a lot of veterans there who have done it before and put up those kind of numbers, and now they've got younger guys like (Yasiel) Puig.''
Didi Gregorius' two-run homer on his first pitch from Edinson Volquez gave the D-backs a 3-2 lead earlier in the inning. Gerardo Parra also scored after drawing a leadoff walk.
The Diamondbacks trailed 2-1 in the fourth on Miguel Montero's RBI single.
Los Angeles led 2-0 in the second on fielder's choice groundouts by Volquez and Yasiel Puig.
Volquez gave up three runs and four hits in six innings of his second start and third appearance as a Dodger since signing on Aug. 30. He struck out five and walked one.
``He's throwing harder now, in the mid-90s instead of the low 90s, and he's keeping guys off balance with that changeup and curveball,'' said Adam Eaton, who went hitless in five at-bats. ``That's the name of the game, and I think he did a good job of that. He was bearing down when there were guys in scoring position.''
Cahill allowed three runs and four hits in six innings, struck out two and walked four.
