"I felt good, but I walked too many guys and created a little trouble for myself," Young said. "I had decent command with the fastball. I didn't use the slider early, but it got better as I went along. I'm trying to make good pitches and that's the bottom line."
Young walked four and struck out three in his third start in San Francisco, where he has never won and had given up 10 runs in his last 10 2/3 innings.
Edwin Moreno (0-2) took the loss after allowing a single to Andres Torres, who then stole second, and giving up an RBI double to pinch-hitter Bengie Molina.
"Edwin threw a good pitch and Bengie hit a high fly ball that we couldn't track down," Padres manager Bud Black said. "It was up in the air a long time and we just couldn't get there. It looked like the wind carried it a little."
Young retired 10 of the first 12 hitters he faced and was able to pitch himself out of a couple of jams.
"It was a tough road trip," Young said. "We went to New York and Philadelphia, had the late night to get here and played three good teams. Five hundred is not bad and we'll take it, but we're not satisfied. We could have easily won a couple more of those games."
The Giants had their leadoff hitter on base in the fourth, fifth and sixth innings. Only one of them got as far as third.
Luke Gregerson retired three of the six batters he faced by strikeout to keep it scoreless after nine innings.
For all their scoring opportunities Tuesday night, the Padres suffered a dearth of chances against Barry Zito. In the seven innings he was on the mound, the Padres managed just one runner in scoring position with less than two outs. They were 0-for-3 with runners in scoring position overall against him.
"He was mixing it in pretty good. He threw the fastball more today than any other time I've seen him, and he was locating it, too," Padres outfielder Scott Hairston said. "He kept his pitches down and when he does it, he's tough to hit. He hit 90 mph once. He was throwing it hard. Both starters threw great."
Hairston doubled to open the eighth and was sacrificed to third by David Eckstein. He was marooned after Brian Giles and Adrian Gonzalez each looked at a called third strike from reliever Jeremy Affeldt.
"In the last three games we had opportunities to add on or score," Black said. "We just couldn't get the big knock. In the first nine games or so, we were getting it. We just have to talk about the importance of timely hitting."
Moreno started the 10th by getting Juan Uribe to ground out. Torres stroked a ground-ball single into right field and stole second on the first pitch to pinch-hitter Eugenio Velez, who eventually struck out. After walking Fred Lewis, the Giants sent Molina to hit for Emmanuel Burriss and Black brought the outfield in, an attempt to neutralize Torres' speed.
"The ball just kept going. It was carrying quite a bit. It was a hard one to catch when you're playing in, trying to cut off the runner and protect against a single," Hairston said. "If we're playing regular depth, that ball is caught, but in that situation you can't play regular depth."
Hairston had two of the Padres' eight hits and San Diego outhit the Giants by a combined 22-13 margin. All the Padres have to show for it is their first losing series.
