Christian Koss' two-run double keyed a five-run 11th inning and the San Francisco Giants beat the Arizona Diamondbacks 5-1 in Phoenix on Wednesday to end a four-game losing streak.

Jerar Encarnacion had a tiebreaking single off John Curtiss (3-2). Grant McCray hit a sacrifice fly and Rafael Devers capped the inning with another run-scoring single as the Giants salvaged the final game of a three-game series.

Starters Brandon Pfaadt and Justin Verlander matched each other through seven innings in a game that was scoreless through 10. Pfaadt threw a career-high nine innings and Verlander went seven, matching his longest outing of the season.

Curtiss, who did not retire any of the four batters he faced, walked Bryce Eldridge to lead off the 11th. Encarnacion dropped a single into center field -- the Giants' second hit of the game -- to score automatic runner Matt Chapman.

Patrick Bailey singled to load the bases, and Koss' two-run double made it 3-0.

The Giants had five hits. Arizona had four, scoring on Corbin Carroll's sacrifice fly off Joel Peguero (3-0) in the 11th.

San Francisco (76-76) remained in a tie with the Cincinnati Reds (76-76), both teams a half-game behind Arizona (77-76) in the chase to catch the Mets (78-74) for the third National League wild card. New York is 1 1/2 games up on the Diamondbacks.

The D-backs had won four in a row and five of six games. They failed in a bid to go three games over .500 for the first time since June 24.

Pfaadt gave up one hit, Drew Gilbert's line single to right with one out in the sixth, while striking out seven and walking one. He threw 97 pitches, 65 of them strikes, while dropping his home ERA to 3.15.

Verlander, who was replaced by Spencer Bivens to open the eighth, gave up three hits and two walks. He struck out three and threw 107 pitches, 67 strikes.

Verlander has allowed one run in 25 innings over his past four starts, but his only decision in that stretch was in a 13-2 victory over Baltimore on Aug. 31.

In the ninth, Gilbert reached first with one out on second baseman Ketel Marte's fielding error, but Heliot Ramos grounded into a double play to end the inning.

The D-backs loaded the bases in their half of the ninth. Carroll hit a one-out triple off Ryan Walker, who then walked Gabriel Moreno and hit Blaze Alexander with a pitch. Walker got out of it with a strikeout and a weak grounder.

Each team had the winning run on third with one out in the 10th but came up empty.
