SAN DIEGO -- Of the first five hitters that Giants pitcher Ryan Vogelsong faced Friday, four of them stung the ball about as hard as a ball can be squared up.
But after he allowed two line-drive singles and two balls that were hit on the screws for outs, Vogelsong didn't allow much of anything else, settling down to lead the Giants to a 3-1 victory over the Padres at Petco Park.
Vogelsong (14-9) allowed one unearned run on five hits over six innings as the Giants captured the first game of a three-game series, the final home series of the season for the Padres, who after a promising second-half run have lost seven of their last 10 games.
"We had a couple of opportunities early. We stressed him a couple of times but couldn't get that big hit. I thought his stuff was as crisp as we've seen it. His fastball was moving. He threw a lot of fastballs," said Padres manager Bud Black.
Vogelsong had a lot to do with this particular loss and he appeared a far different pitcher than when the Padres saw him last, when he allowed three runs on eight hits in just three-plus innings on Aug. 19.
"He settled in nicely and was aggressive with his fastball," said Padres right fielder Will Venable. "There weren't a whole lot of opportunities after that."
Venable had two of the Padres' seven hits, as San Diego managed to mount a late run in the ninth inning when Mark Kotsay and Yasmani Grandal each contributed pinch-hit singles before another pinch-hitter, Carlos Quentin, grounded out to end the game.
San Francisco reliever Santiago Casilla got the last three outs of the game for his 25th save of the season.
The Padres threatened early, getting two baserunners in each of the first two innings. Then in the sixth inning, Vogelsong's final frame of the game, he allowed a single to Venable and then a single to Yonder Alonso that scored a run. But the inning eventually ended when Cameron Maybin bounced hard into a double play.
Again, it was more solid contact that didn't result in much.
San Diego rookie pitcher Andrew Werner (2-3) allowed three runs on eight hits over 4 2/3 innings. He walked one and had two strikeouts.
Werner, a left-hander who was making his sixth career start, has allowed eight earned runs over his last two starts after allowing a combined seven earned runs in his first four starts.
"I thought his stuff was fine. The changeup came into play but his pitch count got up there," Black said. "The Giants seemed to be bit more selective as the game went on."
Pablo Sandoval, a switch-hitter batting right-handed, had a two-run double in the third inning to give the Giants a 3-0 lead.
For his struggles Friday, Werner has limited left-handed batters to a .175 record this season.
As for the Giants, catcher Buster Posey had a double and triple to raise his average to .334, a figure that continues to lead the National League.
San Francisco second baseman Marco Scutaro had one hit in two at-bats before leaving the game with head and chest congestion. His replacement, Ryan Theriot, added two hits. He's hitting .513 this season in 39 at-bats against the Padres.
As for Vogelsong, he attributed part of his slow start -- if you could call it that -- for being a little bit uncomfortable on the mound.
"It took me the first two innings, really, to adjust to the mound. I think the slope's just a little bit different. I had to make some adjustments," he said.
