SAN FRANCISCO -- Bengie Molina felt a tangible difference in the stadium with his former teammate in the stands.
"I just had a very productive out," Molina said. "That's all."
Not exactly the sort of powerful offense Bonds provided during his 15 seasons with San Francisco. Baseball's home run king was a surprise guest Monday night, his first appearance at AT&T Park this season.
"Wherever he goes, he's a big presence," Molina said. "He probably changed the game forever. He's a big part of our team and he makes it easy to communicate with him."
Bonds received a warm welcome and waved to fans when he was introduced to the crowd on Star Trek Movie Night, with costumed Trekkies in abundance among the 31,091 in attendance. He sat between team CEO William Neukom and president Larry Baer next to the Giants' dugout.
"There was good electricity from him," Giants closer Brian Wilson said. "He came into the locker room before the game and it was exciting for me."
Wilson said he was influenced by the crowd when he went out to pitch the ninth.
"They were into it and I took their positivity with me," he said. "I tried to be one with the crowd and give them what they wanted to see -- not only a win over the Dodgers, but over the first-place Dodgers."
Zito took a shutout into the seventh inning but was left with a no-decision. Merkin Valdez (1-0) got the win and Wilson struck out the side in the ninth for his fourth save.
"I'm still upset at myself for walking [Mark] Loretta and not bearing down on Blake," Zito said. "Sure I was starting to tire, but I have to bear down. It's strictly mental."
Dodgers starter Randy Wolf pitched six solid innings. He settled down after the first, retiring 16 of his final 18 batters. He allowed six hits and no walks.
"I'll keep going out there and throw the best I can. That's all I can do," Wolf said. "We're a good team. We'll recover."
Fred Lewis and Renteria opened the bottom of the eighth with singles, putting runners at the corners. After Winn struck out, Aurilia hit a tapper toward first that was fielded by reliever Ronald Belisario (0-2), who tried to tag Aurilia as he was running up the line.
But the ball popped out of Belisario's grasp as he attempted the tag, allowing Lewis to score and Aurilia to reach safely on a failed fielder's choice.
After a wild pitch by Belisario allowed two runners to advance, Renteria scored the go-ahead run on Molina's slow grounder to third.
Zito had his 13-inning scoreless streak snapped in the seventh and remains winless in his last 10 April starts. He pitched 6 1/3 innings, allowing three runs and five hits.
"He's pitched well against us," Dodgers manager Joe Torre said. "He worked fast, threw a lot of strikes and knew what he wanted to do."
Dodgers 1B James Loney didn't start because of his .050 average (1-for-20, six strikeouts) against Zito. ...
