“I told him that I’ve been a horse in Atlanta,” Wood said. “I said, ‘if you just have that faith in me, more times than not hopefully I’ll be able to reward you.’ Fortunately enough I was able to do it tonight.”Wood allowed three singles and walked four, but the Padres did not get a runner past second base. Wood is 3-3 with a 3.43 earned-run average in seven starts since the Dodgers acquired him in the three-team, 13-player trade from the Atlanta Braves.When Mattingly removed Wood in the seventh inning of the Dodgers’ game in Cincinnati on Aug. 14, Wood didn’t react well. He threw his glove angrily down a tunnel leading from the dugout and didn’t address the matter after the game.“I think we’ve seen that when he’s with Atlanta,” Mattingly said of Wood. “There’s been a couple games where we had him in trouble and he just hangs in there. There were a few games where we didn’t think he was coming back out and he did. That competitiveness is always there.”The brisk, low-scoring game was a stunning turnabout one day after the two teams combined for eight home runs. The Dodgers had scored seven runs on Thursday and eight on Friday. Saturday, they only needed two: on back-to-back doubles by Andre Ethier and Carl Crawford in the fourth inning, and an RBI single by Joc Pederson to drive in Ethier in the eighth.Ethier finished 3 for 4 in his first action since missing two straight games with a bruised right knee. The right fielder also made a sliding catch to rob Austin Hedges in the second inning.Chris Hatcher pitched a 1-2-3 eighth inning and has a 1.74 ERA in 10 appearances since he was activated from the 60-day disabled list. Kenley Jansen pitched a perfect ninth inning for his 29th save of the season.The two teams close out the four-game series Sunday. The San Francisco Giants beat the Colorado Rockies earlier in the day so the Dodgers maintained their season-high 7 1/2-game lead in the National League West.Dodgers catcher Yasmani Grandal went 0 for 3, extending his streak of at-bats without a hit to 33. He is likely to get a day off Sunday, a day game in San Diego.“He has the ability and we believe in him,” Dodgers manager Don Mattingly said of Grandal. “It’s there, it’s just a matter of him finding it again. We’re looking more than that (offense) out of that position you’re looking for all parts of it — blocking, defense, the whole thing.” Newsroom GuidelinesNews TipsContact UsReport an Error SAN DIEGO >> Alex Wood began the season with the Atlanta Braves and did not begin it well. After his first seven starts, the 24-year-old left-hander had a 4.28 earned-run average and only one win to show for his efforts.Then, in the middle of May, Wood seemed to find his groove. He began pitching deeper into games, throwing at least seven innings in six of his next 12 starts. He lowered his ERA to 3.54. Then he was traded to the Dodgers.For his first month in a Dodger uniform, Wood had not been allowed to complete seven innings. That changed when Wood dominated the San Diego Padres without allowing a run in the Dodgers’ 2-0 victory at Petco Park.Wood didn’t have to ask Don Mattingly to stay in the game at any point Saturday, even when he was due to bat leading off the seventh inning with the Dodgers nursing a 1-run lead. He had already done so in a private meeting recently.
