PHOENIX -- Patrick Corbin remained one of the National League's hottest pitchers, limiting the Giants to five hits in seven-plus innings, and the D-backs erupted for nine runs in the eighth inning, completing a three-game series sweep with an 11-0 triumph Sunday at Chase Field.
The left-hander, known as "Corby" (12-11) for Players Weekend, won his fourth consecutive start, a stretch in which he has posted a 0.30 ERA. D-backs starters are 5-1 with a 1.45 ERA in the team's last seven games, helping Arizona remain 1 1/2 games ahead of Colorado in the NL Wild Card race.
"He stayed on the corners and moved the ball," Giants cleanup hitter Buster Posey said of Corbin. "It didn't seem like it was in the middle of the plate very much."

Giants rookie right-hander Chris Stratton (2-3) also pitched effectively, though his scoreless-innings streak ended at 15 1/3. The D-backs twice nicked "Strat," scoring without benefit of a hit in the third inning before J.D. Martinez ("Flaco") homered in the sixth.

Martinez also homered in the nine-run eighth, hitting the second of back-to-back-to-back homers between Paul Goldschmidt ("Goldy") and Daniel Descalso ("Scals").
Martinez and Descalso scored on Chris Herrmann's ("Herrm the Worm") two-run single to begin the eighth, making it it 4-0 before each stepped to the plate later in the inning and hit a solo shot.
Sunday marked the eighth time in franchise history that the D-backs have scored at least nine runs in an inning. Three of those instances have come this season.

"It was fun to see," Arizona manager Torey Lovullo said. "We haven't had a lot of those moments as of late. Back-to-back-to-back home runs, J.D. Martinez with two home runs, Goldy another home run -- they really broke the game open, and then Daniel Descalso with the solo home run. Just a really nice day offensively; it was a total lineup contribution and we executed when we had to."
With the win, the D-backs locked up their seventh series sweep of the year and the first since they swept the Phillies in Philadelphia on June 16-18.
The Giants, who formerly excelled away from home and against NL West rivals, have lost 13 of their last 16 road games and have a 3-16-2 record in road series. They're also in a 3-12 skid against teams within the division.
The last time the Giants were shut out in a game at Chase Field was Sept. 16, 2008.
MOMENTS THAT MATTERED
Too good: Stratton had excellent movement on his pitches all afternoon. One particular delivery got him in trouble, however. Stratton fanned Rey Fuentes on a sharp-breaking curveball with two outs and Herrmann on third base in the third inning. Stratton's pitch hit the dirt and bounced away from catcher Nick Hundley for a wild pitch that allowed Herrmann to come home with the game's first run.

Two bad: The Giants grounded into three double plays, ending rallies before they started. Posey was a first-inning victim, spoiling a two-on, one-out threat for the Giants. Kelby Tomlinson lined a fourth-inning leadoff single that went to waste when Hunter Pence grounded into a 6-4-3. And Arizona reliever Andrew Chafin induced a double-play grounder from pinch-hitter Brandon Crawford.

PERALTA EJECTED
David Peralta was ejected in the bottom of the fifth after he struck out on a foul tip, and then slammed his bat on the ground and began arguing with home-plate umpire Ron Kulpa. It was the first time in his career that Peralta has been ejected from a game.
"[Kulpa] said that there was an equipment fine, so he initially did not get thrown out, and then I guess the umpire said that David swore at him," Lovullo said. "I haven't had a chance to check in with David. I don't know what happened, I just know that David doesn't necessarily swear a lot, so I'll be curious to hear what he has to say."

REPLAY REVIEW
In the top of the first, Posey was called safe at first to break up what would have been an inning-ending D-backs 4-6-3 double play. Arizona challenged the call on the field, and after a video review, it was overturned.
In the bottom of the sixth, Goldschmidt attempted to steal second after leading off the inning with a walk. He was called out on a tag from Giants second basemen Joe Panik. Arizona challenged the call on the field, and after a video review, the call stood.

WHAT'S NEXT
Giants: San Francisco ventures to San Diego for a three-game series starting Monday. Jeff Samardzija, 7-3 with a 4.02 ERA lifetime against San Diego, but 0-1 with a 7.27 ERA against the Padres this season, will start the 7:10 p.m. PT encounter for the Giants.
D-backs: The D-backs will begin a three-game series with the Dodgers on Tuesday at Chase Field. Zack Godley, who delivered a quality start and held the Dodgers to three runs over 6 2/3 innings on Aug. 8, will get the start for the D-backs. First pitch is scheduled for 6:40 p.m. MST.
