LOS ANGELES -- Center fielder Wil Myers' RBI single drove in the go-ahead run in the ninth inning, and the San Diego Padres earned a 7-3 victory over the Los Angeles Dodgers on Tuesday night before a crowd of 40,356 at Dodger Stadium.

Shortstop Clint Barnes led off the ninth with a base hit and advanced to third on a sacrifice by pinch-hitter Cory Spangenberg, who was safe at first after the throw by catcher Yasmani Grandal, a former Padre, hit him.

Catcher Derek Norris added a two-run double and third baseman Will Middlebrooks singled home Norris to cap the four-run ninth.

Reliever Joaquin Benoit (1-0) gave up a run in the eighth, while newly-acquired closer Craig Kimbrel struck out the side in the ninth.

Los Angeles reliever Chris Hatcher (0-1) failed to retire a batter in the ninth and allowed four runs (two earned) on three hits.

First baseman Yonder Alonso's two-out RBI single in the eighth gave the Padres a 3-2 lead.

However, Dodgers first baseman Adrian Gonzalez's hit a towering blast off Benoit in the bottom of the inning to tie the score again at 3. It was Gonzalez's second home run in as many games.

Dodgers starter Zack Greinke worked a solid six innings, limiting the Padres to a run on two hits. Greinke, who never lost to San Diego in eight career starts, struck out four and walked one on 94 pitches (61 strikes).

Padres right-hander Tyson Ross had an uneven performance, giving up two runs on six hits with three walks and four strikeouts. Ross blanked the Dodgers until the sixth inning.

That's when the Dodgers rallied from a one-run deficit with three consecutive hits off Ross. Right fielder Yasiel Puig led off the inning with a double to left and scored on Gonzalez's run-scoring double to tie the score at 1 with one out.

Second baseman Howie Kendrick followed by driving in Gonzalez for a 2-1 advantage.

Shortstop Jimmy Rollins committed his second error of the game, misplaying a bloop into shallow center by pinch-hitter Yangervis Solarte in the seventh that scored Alonso and knotted the score at 2.

In the top of the first, Carl Crawford's attempt to make a diving catch on liner to left resulted in a two-out, RBI triple by Padres left fielder Justin Upton. The hit scored center fielder Matt Kemp, who reached on a single.

NOTES: The game was delayed 30 minutes at the start due to rain. The light showers also forced the Padres to cut short batting practice and their pregame fielding work. ...
