DENVER – Aaron Cook neutralized Barry Bonds and knocked in a run with a sacrifice bunt in Colorado’s 5-3 win over the San Francisco Giants.

Troy Tulowitzki hit a two-run double off Noah Lowry (4-3) in the third and scored from second base when shortstop Omar Vizquel threw wildly past third base after fielding Matt Holliday’s bouncer.

The Rockies made it 4-0 in the fourth when Cook sacrificed a runner home with a bunt. First baseman Ryan Klesko fielded it and threw to first for the second out of the inning instead of home for a play at the plate.

Cook (2-1) allowed three earned runs on six hits and four walks without a strikeout in six innings. He cruised until the sixth when San Francisco got all its runs on two-out, RBI singles by Ray Durham, Benji Molina and Fred Lewis.

Lowry gave up four runs, two earned, on six hits and four walks in seven innings.

Bonds leads his team in several offensive categories and now that he’s within 10 of Hank Aaron’s record 755 home runs, he can expect to see a lot more bases on balls than pitches to hit, although on this night he got to take plenty of cuts and was walked only once.

Colorado manager Clint Hurdle said before the game that he’s going to walk the San Francisco slugger every chance he gets during the teams’ four-game series at Coors Field.

“If there’s a base open we’re going to put him on,” Hurdle said. “I’m not going to let him beat our ballclub. It got 25 guys to answer to … I’ve got ownership to answer to. One of the groups I don’t have to answer to is to fans who want to watch Barry hit. I don’t have to answer to those people.”

He strayed from that strategy, however.

In the fourth inning Bonds came up with the bases empty and one out with the Giants trailing by three runs. Cook went at him and he doubled on a 3-1 pitch off the right-field wall, narrowly missing his 746th homer.

With one out and first base open again in the sixth, Cook pitched to Bonds and got him on a groundout to first base before Durham, Molina and Lewis hit run-scoring singles.

In the seventh, Bonds came up for the fourth time with first base open and this time he was intentionally walked, putting runners at first and second with two outs. Manny Corpas got Durham to fly out to shallow left to end the threat.

Corpas also threw a scoreless eighth inning before Brian Fuentes pitched the ninth for his ninth save in 10 tries, getting Durham to line into a double play to shortstop Tulowitzki with two runners on.

The Rockies added an insurance run in the eighth when Holliday tripled and scored on Garrett Atkins’ sacrifice fly.

Giants manager Bruce Bochy understands why Bonds isn’t going to see many strikes now that he’s red-hot and closing in on history: “When you’re swinging the bat the way Barry is, it doesn’t surprise any of us if they’re going to walk him with a base open,” Bochy said.

Bochy, who managed the Padres for a dozen seasons before joining the Giants during the winter, still regrets pitching so much to Bonds, who has hit 86 home runs against San Diego, more than any other team.

“A part of this game is being competitive and I didn’t want to send a message to my guy that hey, you can’t make a quality pitch to get this guy out,” Bochy said. “There were times that it did work for us but a lot of times it didn’t.”

Notes: Vizquel tied Ozzie Smith’s major league record for shortstops with his 1,590th double play in the seventh. … Giants CF Dave Roberts will undergo surgery on his left elbow that could sideline him for a month. … The Rockies joined the growing list of teams to ban beer in the clubhouses following the alcohol-related traffic death of St. Louis Cardinals P Josh Hancock.
