SAN FRANCISCO -- Robbie Ray made a big splash with his bat Tuesday night.

And after teammate Jake Lamb provided a big hit, Ray did the rest with his arm.

The left-hander shut out the San Francisco Giants for 6 2/3 innings and sparked a three-run uprising with a leadoff single, helping the Arizona Diamondbacks continue their winning ways with a 4-3 victory.

Lamb cleared the bases with a third-inning triple off Giants starter Jeff Samardzija, giving Ray an early cushion that resulted in the Diamondbacks' seventh win in nine games this season, equaling the best start in franchise history.

"I felt good at the plate," Ray said of his rally-igniter that followed two loud foul balls, one that splashed into the San Francisco Bay on the foul side of the right field foul pole. "It was great to contribute to the win (with the bat)."

Diamondbacks relievers J.J. Hoover, Jorge De La Rosa and Fernando Rodney allowed all the Giants' scoring over the final two innings, with Rodney picking up his third save despite allowing two runs in the ninth.

The Arizona closer struck out pinch hitter Brandon Crawford with the potential tying run at second base to end the game.

The Giants stranded 13 baserunners, the Diamondbacks 10.

"We just couldn't get the big hit," Giants manager Bruce Bochy said after his team's sixth loss in nine games. "We left too many men on base. We've got to start to find a way to get these runs in."

After he escaped a bases-loaded Giants threat in the second inning, Ray smacked a single up the middle off Samardzija to open the Arizona third.

A single by A.J. Pollock and one-out walk to Paul Goldschmidt loaded the bases for Lamb, whose long fly barely eluded the glove of Giants center fielder Gorkys Hernandez, who appeared to slow up as he approached the outfield fence.

The ball caromed off the bottom of the wall, easily allowing all three baserunners to cross the plate and providing Ray an early lead.

The triple extended Lamb's hitting streak to eight games.

"What Goldy did was hand it off to the next guy," Diamondbacks manager Torey Lovullo said of his slugger, who patiently worked Samardzija for the walk that loaded the bases. "Jake Lamb has worked long and hard to get into that situation, and he took advantage."

Still leading 3-0, Ray (1-0) was pulled with one on and two outs in the San Francisco seventh. He pitched around four singles and five walks, striking out eight.

The Diamondbacks added an insurance run off Giants reliever Neil Ramirez in the eighth on an RBI single by Chris Iannetta, scoring Yasmany Tomas, who had doubled.

Samardzija (0-2) held the Diamondbacks to three runs despite allowing five hits and four walks in 6 2/3 innings. He struck out seven.

Samardzija also hit Goldschmidt on his back pocket with a first-inning fastball, and he wouldn't deny afterward it was in retaliation for Diamondbacks pitcher Taijuan Walker nailing Giants star Buster Posey in the head in Monday's game.

Posey was placed on the seven-day concussion disabled list Tuesday.

"You decide," Samardzija responded when asked if his pitch to Goldschmidt was retaliation. "We've got to attack him in. He took me (to right field for a home run) at their place. I obviously didn't feel like any pitches out over the plate was a good idea. I went in, and that was it."

The Giants finally got on the scoreboard in the eighth against the third Arizona pitcher, De La Rosa. Doubles by Hundley and Joe Panik produced the run.

Lamb and Tomas had two hits apiece for the Diamondbacks, who were outhit 10-9.

Eduardo Nunez had four singles and Hundley two doubles and a single for the Giants, who lost for the fourth time in six early-season meetings with the Diamondbacks.

Hunter Pence reached base five straight times for the Giants with two singles and three walks.

The Diamondbacks' three-run third came immediately following a second inning in which the Giants nearly scored four.

After San Francisco loaded the bases on a Nunez infield single and a pair of one-out walks, Samardzija struck out for the second out before Hernandez hit a high, deep fly to left.

Tomas hauled it in at the fence, preserving the 0-0 tie.

"That was the big turnaround," Ray said. "I knew I got him a little out front on it, but the wind was blowing out to left. I knew there was a chance it would go out, but I knew he didn't hit it that well."

NOTES: To take C Buster Posey's spot on the active roster, the Giants promoted veteran C Tim Federowicz from Triple-A Sacramento. The ex-Chicago Cub struck out as a pinch hitter in the seventh inning. ... In order to create room for Federowicz on the 40-man roster, the Giants designated RHP Clayton Blackburn for assignment. ... LHP Robbie Ray's strong performance continued a nice run for Diamondbacks starters. The Arizona rotation entered the game ranked third in the National League in innings pitched (43 2/3) and fourth in ERA (3.50) and opponents' batting average (.238).
