Landen Roupp outpitched Yoshinobu Yamamoto, San Francisco got RBI singles from Rafael Devers and Jung Hoo Lee in a three-run first inning and the Giants held off the visiting Los Angeles Dodgers 3-1 in the opener of a three-game series Tuesday night.

Roupp (4-1) allowed just one run on one hit in five innings, then watched five relievers combine for four innings of shutout ball, helping the Giants open a six-game homestand with a win after a 4-5 trip.

Roupp struck out seven and walked five in his first career win over the Dodgers.

Seeking his first-ever victory over the Giants, Yamamoto (2-2) went seven innings, allowing six hits and three runs, all of which scored in the first. He walked two and fanned seven.

Willy Adames got the cold night rolling for San Francisco with an infield single, after which Luis Arraez singled and Matt Chapman walked to load the bases.

Each of the next three batters delivered single runs, with Devers’ single chasing home Adames, Casey Schmitt’s sacrifice fly scoring Arraez and Lee’s single plating Chapman.

Roupp allowed a two-out single by Hyeseong Kim in the second but no other hits until a wild spate in the fourth. He walked four of the first five batters he faced that inning, including Kim with the bases loaded to force home Teoscar Hernandez.

The right-hander got out of the one-out jam by inducing a double play grounder off the bat of Alex Call.

The Dodgers got the potential tying run on the bases with two outs in the seventh before Erik Miller struck out Kyle Tucker to retain the 3-1 lead.

Ryan Walker worked a 1-2-3 ninth inning for his second save.

Ryan Borucki, Matt Gage and Keaton Winn also contributed to the three-hitter in the first meeting of the season between the longtime California rivals.

Lee was the only player in the game with multiple hits, a pair of singles. The Giants out-hit the visitors 6-3, with the Dodgers’ Hernandez stroking the game’s only extra-base hit, a double.
