SAN FRANCISCO -- The Arizona Diamondbacks wasted numerous scoring opportunities against San Francisco Giants ace Madison Bumgarner on Friday night, turning 12 baserunners in the left-hander's eight innings into just one run.

Turns out, that was all right-hander Chase Anderson needed.

Focusing more on winning than history, Anderson took a no-hitter into the seventh inning and combined with two relievers on a two-hit shutout, lifting the Diamondbacks to a 1-0 victory over the Giants in the opener of a three-game series.

"I like pressure situations. I've always thrived off of that," Anderson insisted. "You focus on each pitch. You go pitch-to-pitch, and that helps me out."

Facing the Giants for the first time in his two-year career, the 27-year-old lost a no-hitter on catcher Buster Posey's infield hit with one out in the seventh.

It was the only hit Anderson allowed in seven innings en route to his first win since May 20. He hasn't lost since April 27, an eight-game stretch during which he's gotten a no-decision six times.

Anderson outpitched Bumgarner, who lost for the first time since May 9.

"I just wanted to give the team a chance to win," Anderson assured. "I knew it was going to be a good game with Bumgarner pitching."

Left fielder Ender Inciarte drove in the only run of the game with a two-out single in the second inning. Anderson entered the game having received the fifth-fewest average run support (2.85 runs per game) in the National League.

"These guys are doing the best they can," Anderson noted. "I'm just focused on doing my job. You look up there and we have just one run. That keeps you more focused."

The win was the Diamondbacks' first in four games on their current eight-game trip. They had lost four in a row overall.

"I think they realize it," Arizona manager Chip Hale said of the club's lack of support for Anderson. "You hear a lot of talk. ... β€˜Let's get him some runs.' Actually, he has pitched better when we don't score."

Anderson (2-1) had allowed only three baserunners -- hitting third baseman Matt Duffy twice and walking Bumgarner -- through 6 1/3 innings before Posey lined a one-hopper off the pitcher's right calf. The ball deflected toward the third-base line, allowing Posey to record his single without a throw.

"I wish it had gone to somebody," Anderson said with a smile. "Maybe if I had turned a little bit more, it would have gone to somebody."

Diamondbacks trainer Ken Crenshaw checked out Anderson and allowed him to continue. He went on to retire the next two batters he faced to complete the seventh inning before turning the ball over to the Arizona bullpen in the eighth.

Right-handers Daniel Hudson and Brad Ziegler pitched a scoreless inning apiece, with Ziegler recording his seventh save with a 1-2-3 ninth.

The closest the Giants came to scoring occurred before they recorded their first hit.

After Anderson hit Duffy for the first time, he issued a one-out walk to Bumgarner to put two aboard.

Left fielder Nori Aoki then hit a liner apparently destined for left field, but Diamondbacks third baseman Aaron Hill leaped to snatch it. He then doubled off Duffy at second to kill the threat.

"That's just reaction," Hill said of the snag. "It was good positioning. It came right at me."

The base-running gaffe was the first of two for Duffy, who led off the eighth against Hudson with a single.

After reaching second on a wild pitch, Duffy got caught straying too far off the base on a hard one-hopper to Arizona second baseman Chris Owings. Duffy got caught in a rundown between second and third, and was tagged out by Hill.

Hudson then retired Aoki on a grounder to first to end the inning, before Ziegler was called upon for the ninth.

"One run ... You think you're going to find a way to
