SAN FRANCISCO (AP) -- For the first time since starting play in 1993, the Colorado Rockies have been shut out in consecutive games.

"It's going to happen to everybody during a season, it just so happens it's happening to us right now," Colorado manager Buddy Bell said Saturday after the San Francisco Giants beat the Rockies 6-0.

Colorado, which led the majors with a .300 batting average coming in, had scored 72 runs in its previous six games before the series.

"Give credit to their pitching," Bell said. "I don't want to mislead anybody. We're not hitting right now, but give credit to them."

Colorado is 0-for-13 with runners in scoring position in the last two games.

"I don't call it a funk," Jeffrey Hammonds said. "I call it good pitching, good defense. We're playing a hot club. We're playing the game. They're just beating us."

Estes (2-1) retired the side in order just twice, but worked out of jams to win his second straight start. He struck out five and walked three in his fifth career shutout and sixth complete game.

"Seems like all we need is to put up a run or two, that's all it takes right now," Estes said. "That's the way it's been going for us the last week or so. It's a nice little roll we are going on right now. Whatever it is, let's just keep doing it."

"When you shut down a high-powered offense -- a team that came in here red hot -- that's impressive," Giants manager Dusty Baker said. "Pitching prevailed."

San Francisco went ahead with an unearned run in the fourth against Rolando Arrojo (1-3). Kent scored from second with two outs when second baseman Mike Lansing overthrew first base on Armando Rios' slow infield chopper up the middle.

Bill Mueller's sacrifice fly made it 2-0 in the fifth, and San Francisco added three runs in the sixth. Kent tripled and scored on an RBI double by Rios. Doug Mirabelli added a two-run single for a 5-0 lead, and Mueller doubled a run in the eighth off Mike DeJean.

Arrojo, pitching for the first time since April 20 following a stint on the disabled list caused by a strained left hamstring, allowed five runs -- four earned -- seven hits and four walks in five-plus innings.

Colorado advanced runners to scoring position four times against Estes. The Rockies loaded the bases with one out in the third, but Todd Helton grounded into an inning-ending double play.

After starting the season 0-6 at home, the Giants have evened their record at Pacific Bell Park at 7-7.

"April wasn't very good for us," Baker said. "So far, May has been great to us. That's why you can't get too high or low, because it can turn around quickly either way."
