Robbie Ray tossed 6 2/3 shutout innings and rookie Daniel Susac went 3-for-4 with two RBIs to help the San Francisco Giants record a 6-0 victory over the visiting Philadelphia Phillies on Tuesday night.

Matt Chapman had three hits and one RBI and Luis Arraez drove in two runs as the Giants snapped a four-game losing streak. Willy Adames added two hits for San Francisco.

Susac's single in the fifth gave him a 5-for-5 start to his major league career, the best career start in the majors since Ted Cox of the Boston Red Sox started 6-for-6 in 1977. Susac popped out in the sixth to end his streak but added a two-run triple in the eighth for his second straight three-hit game, not including a game in which he appeared only on defense.

Ray (2-1) struck out seven and gave up three hits and three walks. Ryan Walker recorded four outs and Keaton Winn worked a perfect ninth for the Giants.

Cristopher Sanchez (1-1) gave up four runs (two earned) and 11 hits in five-plus innings for Philadelphia. He struck out six and walked none as the Phillies lost for just the second time in the past seven games.

San Francisco struck in the first when Adames led off with a double, moved to third on a single by Chapman and scored on Arraez's groundout.

Susac led off the fifth with a single to surpass the Giants' record of a 4-for-4 career start by Hall of Famer Willie McCovey in 1959. Jared Oliva followed with a likely double-play grounder to Phillies shortstop Trea Turner, who fumbled the ball to put runners on first and second.

Two outs later, Chapman ripped a double over the head of left fielder Otto Kemp to give the Giants a 2-0 lead. Arraez followed with a single for a three-run lead.

San Francisco tacked on another run in the sixth. Rafael Devers singled and Casey Schmitt hit a ground-rule double to center, ending Sanchez's night. Pinch hitter Jung Hoo Lee lofted a sacrifice fly off Zach Pop to score Devers.

Ray walked Edmundo Sosa to start the seventh and issued a two-out free pass to Dylan Moore. Walker entered and retired Justin Crawford on a comebacker to end the inning.

Susac continued his heroics in the eighth with a two-run triple down the right-field line to improve to 6-for-7.
