Nolan Arenado and Troy Tulowitzki sat in the dugout Saturday morning sharing their misery of AT&T Park.

It feels like Halloween with the rowdy sellout crowd draped in black and orange. And it might as well be, given the Stephen King novel that plays out when the Rockies stumble into the place.

Remember the time Chris Iannetta wound up playing third base and Garrett Atkins second after Jeff Baker hurt his finger in warm-ups and Tulowitzki was sidelined 20 minutes later with a leg injury? Or what about last May 25, when Angel Pagan rambled around the bases for an exhausting inside-the-park walk-off home run, the first in baseball since 2004?

Friday featured Madison Bumgarner's grand slam, only the second by a Giants pitcher since the team moved to San Francisco in 1958.

So when Brett Anderson exited in the fourth inning with a bruised left finger, the Rockies were bracing for absurdity and cruelty to collide once again at their expense.

But the bullpen refused to buckle, the maligned catcher pounced like a puma, the offense played small ball and the Rockies secured a 1-0 shutout, their first in San Francisco since 1998.

"Everbody got panicked when we lost 'Andy,' then guys quickly got settled," reliever Adam Ottavino said. "Usually a one-run game here is going the other way. We kept them quiet, and it gives us a lot of confidence."

Anderson was uncertain whether he would make his next start Thursday at San Diego. Feeling and mobility returned to the finger, but it was heavily wrapped.

"I hit a sinker off the end of the bat, and it was like a firework went off in my batting glove," Anderson said.

For those who keep track of such things: Jhoulys Chacin is hurt, Anderson is hurt, Tyler Chatwood was hurt and it hurts to watch Jorge De La Rosa.

That's why this win carried added significance. The Rockies turned a blueprint for failure into a building block. It started and ended with a mighty 'pen.

Rookie Tommy Kahnle delivered two scoreless innings, navigating trouble after allowing the first two runners to reach in the fourth.

"He's fearless," outfielder Michael Cuddyer said.

Each of five relievers passed the baton, protecting a lead that was gained through a formula foreign to Rockies fans on the road: walk, single on a hit-and-run, double steal, Tulowitzki sacrifice fly.

"We found a way," Tulowitzki said.

The eighth was the tipping point. Rex Brothers walked Hunter Pence, loading the bases with two outs. In stepped Pablo Sandoval, baseball's best bad-ball hitter. Brothers fired three straight fastballs, jumping ahead 0-2. He then uncorked an 87 mph slider that catcher Wilin Rosario deftly backhanded as he fell to his chest, saving a run. Brothers followed with a more accurate pitch in the dirt, retiring Sandoval.
