SAN DIEGO -- With Barry Bonds back in the cleanup spot and Matt Morris pitching well, the San Francisco Giants looked like a much different team.

Bonds hit an RBI single and scored a run, and Bengie Molina drove in two runs to lead the Giants to a 6-5 win over the San Diego Padres on Tuesday night. It was the second win this season for the Giants, who snapped a four-game losing streak.

The Giants led 6-0 in the middle of the fifth inning, which for them qualifies as an remarkable offensive uprising. The season-high six runs matched the Giants' total output in their four consecutive losses.

"A much better job," said manager Bruce Bochy, who tweaked the lineup by dropping Bonds from third into the cleanup spot. "We did some good things tonight, executed better. We got a couple of breaks and we know it. They looked a lot looser tonight. This was a good ballgame for us."

A night earlier, the Giants lost 1-0 despite Matt Cain and Jonathan Sanchez combining to hold the Padres to two hits.

"Cainer's game yesterday, there was some sting left in the game until the end," Morris said. "Today we kind of took the sting out of it a little earlier and had some margin for error."

Morris has both of San Francisco's wins after beating the Padres for the second time in six days.

San Diego's Clay Hensley, who lost both of those games to Morris, allowed all six runs, four of them earned. San Diego's bullpen pitched 4 2/3 scoreless innings to extend its season-opening streak to 25 1-3 innings without allowing a run.

Adrian Gonzalez hit his second home run of the game with two outs in the ninth to pull the Padres within 6-5, but Armando Benitez recovered, earning his second save in as many chances by inducing Khalil Greene to fly out to end the game.

Bochy, who has two wins in five games against his former team, said he'd been thinking about the lineup switch for a few days to try to jump-start the offense. Bonds began the season in the No. 3 spot in part because Bochy liked the idea of the slugger having a first-inning plate appearance.

Bonds was 1-for-2 with two walks, one intentional. Rich Aurilia batted third and went 2-for-5 with an RBI single and a run scored.

"We were sputtering and it was time to do something different," Bochy said. "It's a team that's going to score runs."

In scoring their first two runs, though, the Giants benefited more from Padres lapses than Bonds' return to the No. 4 spot.

San Francisco scored two unearned in the second inning thanks to second baseman Marcus Giles' error on Bonds' leadoff grounder. Giles, who was playing several feet farther to his left than normal and well back on the outfield grass as part of the "Bonds shift," bobbled the ball and his throw to first was late.

Center fielder Mike Cameron then lost Ray Durham's ball in the lights and it fell in for a double. Molina singled in Bonds and Durham took third. Hensley somehow lost track of Durham because after he fielded Randy Winn's comebacker, he looked at second before throwing to first, allowing Durham to score for a 2-0 lead.

"I should have gone home there," Hensley said. "That's one of the things I can take from this game."

Molina had an RBI grounder in the fourth. Morris hit a leadoff single and scored in the fifth, when the Giants took a 6-0 lead. With Morris on third and former Padres outfielder Dave Roberts on second with one out, Aurilia and Bonds hit consecutive RBI singles to chase Hensley. Mike Thompson came on and allowed Durham's sacrifice fly.

Morris allowed two runs and seven hits in 5 1/3 innings, struck out three and walked four. Hensley (0-2) struck out four and walked two in 4 1/3 innings.

Hensley said a blister that developed on his right middle finger in his season debut wasn't a factor. "It's not as bad as it was in San Francisco," he said.

Gonzalez had four RBI in the game. He homered off Kevin Correia in the seventh and had an RBI single off Morris in the fifth.

Notes

• Bonds had been 1-for-10 lifetime against Hensley before his fifth-inning single.
• Padres 3B Kevin Kouzmanoff is expected to sit out a few games with a sore left elbow after he was hit by a pitch from Matt Cain on Monday night. Manager Bud Black expects him to be ready by Friday, when the Padres open a three-game series at the Los Angeles Dodgers. Kouzmanoff could be called on to pinch-hit Wednesday night against the Giants, if necessary.
