SAN FRANCISCO -- San Francisco Giants manager Bruce Bochy insisted after Friday's loss to the Arizona Diamondbacks that his team needed to win the rest of its games to have a chance to win the National League West.

But the Diamondbacks showed up again at AT&T Park on Saturday, and that was that.

Arizona continued its mastery of the Giants at AT&T, riding seven-hit pitching and a 17-hit attack to a 6-0 victory.

"I wish I could explain it. I'm buffaloed," Bochy admitted. "There's no rhyme or reason. They've done a number on us. I'm a little stunned, to be honest."

Center fielder A.J. Pollock, right fielder Ender Inciarte and left fielder David Peralta each had three hits as the Diamondbacks improved to 8-1 in San Francisco this season with a sixth consecutive victory on Giants turf.

Pollock scored twice, while Inciarte drove in a pair of runs.

Third baseman Jake Lamb and shortstop Chris Owings each had two hits for the Diamondbacks, whose eighth road win against the Giants matched a franchise record.

The Diamondbacks (71-77) will get a chance to better it in the series finale Sunday.

Following up on a two-hit shutout by right-hander Rubby De La Rosa and four relievers in the series opener Friday night, lefty Patrick Corbin blanked the Giants on five hits over seven innings.

Right-handers David Hernandez and Josh Collmenter finished up the Diamondbacks' 11th shutout of the season, as the Arizona pitching staff ran its string of consecutive scoreless innings at AT&T to 30.

"Those things you really don't talk about," Diamondbacks manager Chip Hale said of the streak. "That's quite an achievement for our pitchers. We've got to continue it (Sunday).

That task will fall upon right-hander Jeremy Hellickson.

"That's the way you compete," Diamondbacks catcher Jarrod Saltalamacchia said of the pressure on Hellickson. "That's the way you get better. That's how good teams start clicking."

Corbin (6-4) lowered his career ERA at San Francisco to 1.00 in three starts. He struck out five and did not walk a batter in seven innings, which equaled his longest outing of the season.

"Everything was working," Corbin explained. "Today they hit the ball right to guys, and they made the plays. I got into a rhythm there."

Corbin credited spacious AT&T Park as contributing to his and the Arizona staff's success.

"It's a good pitchers' park. Everybody knows that," he said. "It seems like one guy here pitches well, and then the next guy does, too. Hopefully that continues (Sunday)."

Corbin also contributed to the Arizona offense with a run-scoring single in the fifth inning to increase the lead to 4-0.

The loss dropped the Giants (77-71), defending World Series champions, nine games behind the first-place Los Angeles Dodgers in the National League West.

The Dodgers hosted the Pittsburgh Pirates in a night game Saturday.

"We can talk about what we don't have, but what's the purpose?" Bochy said of his injury-riddled team. "I thought we threw a pretty good lineup out there. Getting shut out back-to-back is something I would not have thought would happen."

Pinch-hitter Ehire Adrianza had the only extra-base hit among the Giants' seven hits, a fifth-inning double.

The assault on Giants pitching began with the first batter of the game, when Pollock smacked a single off San Francisco starter Mike Leake.

Pollock came around on singles by first baseman Paul Goldschmidt and Peralta, recording his 100th run of the season.

The Diamondbacks made it 3-0 in the second on RBI hits by Owings and Inciarte, and ended Leake's day after adding two more hits - but no runs - in the third.

Leake (10-9) left having allowed three runs on eight hits in three innings. He walked one and did not strike out a batter.

The Diamondbacks added single runs against the San Francisco bullpen in the fifth on an RBI single by Corbin, the sixth on Inciarte's second run-scoring hit, and the eighth on an RBI double by Saltalamacchia.

All nine Arizona starters had at least one hit.
