SAN FRANCISCO (AP) — The countdown is on. Barry Bonds is closing in on Hank Aaron in a hurry.

Bonds hit his 740th home run Sunday, connecting for the second consecutive game and helping Matt Cain earn his first win of the season in the San Francisco Giants’ 2-1 victory over the Arizona Diamondbacks.

“It’s awesome for him to be swinging it like he’s swinging it,” Cain said.

Cain wasn’t bad himself.

The right-hander pitched a three-hitter for his third career complete game and first since a one-hitter last May 21 at Oakland. He struck out four and walked four in a game that lasted just 1 hour, 56 minutes. It was the fastest nine-inning game in the major leagues since Arizona beat St. Louis 3-0 in 1 hour, 54 minutes on Sept. 9 last season, according to the Elias Sports Bureau.

Bonds moved within 15 homers of Aaron’s record. With two outs in the fourth inning, he sent the first pitch from Yusmeiro Petit (0-1) into the seats in the right-field arcade for his sixth homer of the season.

“He doesn’t have anything bothering him,” Giants second baseman Ray Durham said. “The sky’s the limit.”

The 42-year-old Bonds walked out to left field in the top of the fifth to a loud standing ovation, tipping his cap as he made his way to his spot. Fans bowed over the left-field fence.

Petit, called up from Triple-A Tucson before the game to make his second major league start, became the 438th pitcher to give up a homer to Bonds.

“He changes your club, your lineup, including the opposing pitcher seeing Barry out there,” first-year San Francisco manager Bruce Bochy said. “I can’t say enough about what he’s done for us the last few days. It’s pretty remarkable what he’s doing at his age. … Since coming over here, it amazes me what he does. It tells you how much better he is than any of the rest of us.”

Bonds flied out and struck out looking in his other two at-bats, but his home run and Pedro Feliz’s shot leading off the third led the Giants to their season-best fifth straight victory.

Bonds hit his 739th homer in the second inning of Saturday’s 1-0 victory to help Barry Zito win at home for the first time with the Giants. This marked the first time Bonds homered in back-to-back games since Sept. 22-23 last year at Milwaukee. Bonds had homers in three in a row from Sept. 2-4, the first two at Chicago and the third in Cincinnati.

Cain (1-1) allowed a leadoff single by Eric Byrnes to start the game, but that was it until Byrnes and Alberto Callaspo each singled with none out in the ninth. Orlando Hudson grounded into a double play to bring in the Diamondbacks’ lone run. Cain, who had thrown 101 pitches at that point, then received a visit on the mound from pitching coach Dave Righetti and stayed in the game.

After walking Chad Tracy, Cain retired Tony Clark on a game-ending grounder. Durham made a great stop on the play. If the ball had gone by him, Cain would have been lifted.

“His fastball has life to it,” Byrnes said. “It has a giddy-up at the end. He’s a different type of guy than Zito. He throws fastballs that register in the low 90s, and they appear a lot faster than that.”

Cain bounced back after a no-decision at Colorado on Sunday, when he pitched seven scoreless innings and allowed only two hits.

“There’s nothing more respectful (than) for him to put the confidence in me to complete the ninth,” Cain said about Bochy. “It was great to be able to be back out there.”

Cain, who led all NL rookies with 13 wins last season, pitched well enough to win in his first three starts. He gave up only three hits in his previous two outings — and one run in 14 innings.

Arizona’s season-long skid reached four games with the club’s sixth defeat in seven games. The Diamondbacks went 1-for-20 during the series with runners in scoring position. They hope getting Randy Johnson back to make his season debut Tuesday against San Diego might help get the team out of its funk.

“We knew in our division pitching was the way it was going to be,” manager Bob Melvin said. “We knew pitching would be the dominant force in the division, and so far it has been. We feel good about Randy going Tuesday.”

Aside from the two homers, Petit was pretty good. He struck out five and didn’t walk a batter, allowing four hits in seven innings.

San Francisco’s Rich Aurilia had his career-high tying 14-game hitting streak snapped with an 0-for-3 day.

Omar Vizquel was robbed of a hit on Byrnes’ diving catch in left-center in the sixth. Vizquel received his 11th Gold Glove before the game, two days before the shortstop turns 40.

Boos rang throughout AT&T Park in Thursday night’s ninth inning after San Diego’s Josh Bard blooped an Armando Benitez pitch into left field for a two-run single. The fans’ displeasure conveyed impending doom. But Benitez, the object of the scorn, remained calm.

“I didn’t worry about it,” he said later with a reassuring smile.

Benitez indeed remained in control of the situation. He coaxed a popup from the next hitter, Mike Cameron, to preserve the Giants’ 5-3 decision over the Padres that gave Bruce Bochy his first managerial victory with San Francisco.

After losing their first two games, the Giants regarded this triumph as more than just a milestone for Bochy.

“I know it’s a long season,” second baseman Ray Durham said. “But you don’t want to be climbing out of an 0-3 hole with L.A. coming in and then going on the road.”

“I’ll be honest. The last thing we wanted to do was to open up this thing getting swept,” Bochy said after the Giants avoided their fifth 0-3 start since moving to San Francisco in 1958.

A lot happened for the Giants before Benitez took the mound: Matt Morris’ six solid innings, Barry Bonds’ first-inning RBI double off the base of the right-center-field wall, sparkling defense and a four-run uprising in the fifth inning that stemmed from patience and luck.

All of it would have been undone if Benitez had squandered his save opportunity — as he did 12 times during the previous two seasons, which fueled the fans’ disdain.

The Giants almost didn’t need Benitez. They took a 5-1 lead into the ninth, which Steve Kline began by retiring the first two Padres hitters. Then Marcus Giles doubled and Brian Giles rolled an infield single up the middle. Although Bochy could have stuck with Kline, a left-hander, to face left-handed-batting Adrian Gonzalez, Benitez was summoned to fulfill his role.

“He’s a closer,” Bochy said. “When it gets to that situation, he’s in the ballgame.”

Benitez promptly loaded the bases by walking Gonzalez on four pitches, although he had a plausible explanation for doing so.

“We did it on purpose,” he said. “Sometimes it’s better if you stay away from somebody who can hurt you. … It’s not like I was afraid of him. I was careful with him.”

Bard’s fly was softly hit but nowhere near a Giants defender, enabling the Giles brothers to score. Up came Cameron, representing the potential go-ahead run. Cameron was 1-for-12 lifetime off Benitez, who remained unimpressed with his own success.

“I didn’t want to play around with Cameron,” Benitez said. “One mistake and he can crush it.”

Cameron lifted a 2-2 pitch to Durham, ending the drama.

After accumulating only nine at-bats with runners in scoring position in their first two games — the 4.5 per-game average was the National League’s lowest — the Giants finally sustained some offense in the fifth, when they broke a 1-1 tie.

San Francisco benefited from San Diego starter Clay Hensley’s wildness and a little luck. With two outs, Hensley prolonged the fifth by walking Roberts, Omar Vizquel and Bonds to load the bases.

After taking a close 3-1 pitch for a strike, Durham singled to right field, scoring Roberts and Vizquel.

“If I hit that ball, I’d beat it into the ground or roll over and hit it to second base or shortstop,” Durham said, referring to Hensley’s 3-1 delivery. “Once he went to 3-2, I knew he didn’t want to walk me and that he’d get something up. I think it was a cutter or a slider he threw and I got pretty good wood on it.”

Rich Aurilia lifted a popup to shallow left field, where Padres third baseman Kevin Kouzmanoff and Khalil Greene, the shortstop, converged on the ball. Kouzmanoff backed into Greene and knocked him over, enabling the ball to fall untouched for an RBI single. Ryan Klesko, who went 3-for-4, followed with a clean single up the middle to drive in the inning’s final run.

Defense contributed to the Giants’ balanced effort. Roberts made a lunging grab of Greene’s fly to shallow center field in the second inning. Durham complemented his clutch hit with a fielding gem, gloving Gonzalez’s sixth-inning grounder by diving to his right and throwing from his knees for the out at first.

Morris, who improved to 7-3 lifetime against San Diego, surrendered only one hit through four innings. Then he became a tightrope walker, stranding two Padres in each of his final two innings.

“I thought that they were pretty aggressive, but I got it in my head that they were going to be aggressive,” Morris said of the Padres hitters.

Getting their first victory out of the way freed the Giants to pursue other objectives.

“Now we can relax and play our archrivals,” Kline said.
