SAN FRANCISCO -- Robbie Ray's winless stretch has reached four games, matching the Arizona left-hander's longest drought of the season.
Diamondbacks manager Chip Hale insists he's not worried, though, and continues to like what he's seeing from Ray even though the results haven't been all that impressive.
Ray gave up three runs Saturday in his third start against San Francisco this season but the Diamondbacks were blanked over the final five innings in a 4-2 loss to the Giants.
"I thought he was a little bit wild in the zone, up in the zone, but he's the one guy we have who can pitch up in the zone," Hale said. "He kept us in the game. Three runs is enough to win most games for us. A step in the right direction."
Ray (4-8) struck out seven, walked three and retired the final five batters he faced after giving up two runs in the fourth including Grant Green's go-ahead two-run home run.
"I was putting guys away with my curveball and my slider and elevating my fastball when I needed to," Ray said. "I felt good. I felt like I managed it well enough to go deeper into the game and give my team a chance to win."
Brandon Belt had an RBI triple, Angel Pagan added two hits and Ruben Tejada doubled in a run for the Giants, who have won seven of nine and are a major league-best 56-33.
George Kontos (2-1), one of six relievers used by manager Bruce Bochy after starter Jake Peavy was knocked out of the game in the fifth, retired four batters for the win.
The Giants' bullpen, which began the day tied with Cincinnati with a major league-worst 17 blown saves, combined for 4 2/3 scoreless innings. Santiago Casilla pitched the ninth for his 21st save.
"Today we needed them," Bochy said. "Jake did a great job of keeping us in the game. The `pen helped win that game for us."
That helped San Francisco to its second straight home win over Arizona after getting swept in a four-game series at AT&T Park in April.
The Diamondbacks trailed 1-0 but took the lead with four consecutive hits to open the fourth before Green's two-run home run in the bottom of the inning put the Giants ahead 3-2.
Arizona put runners on the corners in the fifth and seventh and also got a runner to third in the ninth but failed to score each time.
Paul Goldschmidt had two hits while Yasmany Tomas and Brandon Drury each drove in a run for Arizona.
Diamondbacks third baseman Jake Lamb lost Brandon Crawford's high pop-up in the sun in the fourth inning and was nearly hit in the head by the falling ball. As it was, the ball hit Lamb in the left shoulder and bounced away. The kicker? Lamb was wearing sunglasses but had them on top of his head and not over his eyes.
"If I had sunglasses on I still lose it because it just went right into the sun," Lamb said. "It goes into the sun all the time but usually if you stay with it it comes out. I had it at first, and it stayed in."
Diamondbacks: RHP Zack Greinke was expected to throw after the game for the first time since going on the disabled list with a strained left oblique last week. ... RHP Daniel Hudson was activated off the bereavement list as planned.
Diamondbacks: RHP Archie Bradley (3-4) starts the series finale Sunday. Bradley has pitched better on the road than at home but is winless in two career starts against the Giants.
Giants: LHP Madison Bumgarner (9-4), who was voted in but will not pitch in the All-Star game, goes for San Francisco. Bumgarner's 2.09 ERA is second-lowest in the majors among qualifiers.
