SAN FRANCISCO -- The Giants have stuck with Tyler Beede through the ups and downs of his rookie season, a sign of their belief in his ability to potentially develop into a long-term piece in their rotation.

The 26-year-old right-hander rewarded that faith again Friday night, tossing 6 1/3 scoreless innings to earn his first home win in the Giants’ 1-0 victory over the Marlins at Oracle Park.

Beede continued to build off his strong outing at Dodger Stadium last week, allowing only three hits while walking one and striking out five. Two fellow rookies helped secure the Giants’ fifth 1-0 win of the season, as Tyler Rogers and Shaun Anderson combined to throw the final 2 2/3 innings to complete the shutout.

“This is a time for these guys to shine and show that they belong up here,” manager Bruce Bochy said. “You’re hoping that they can pitch here or play here, so it was a really nice job by the three kids today. That’s a close game, a one-run ballgame that didn’t faze them at all.”

Bochy now has 1,997 career wins, leaving him only three shy of becoming the 11th Major League manager to reach 2,000.

Beede outdueled Marlins right-hander Sandy Alcantara, who blanked the Giants through the first five innings of the game before Stephen Vogt doubled and scored on a single by Buster Posey to break the stalemate in the sixth.

The performance marked another step forward for Beede, who endured a rough stretch for much of the second half and saw his ERA spike to 5.82 following a disappointing start against the Cubs on Aug. 20. He finally broke out of the deep rut by firing five shutout innings against the Dodgers on Saturday, drawing encouragement from his ability to handcuff one of the most formidable teams in the National League. Before that, Beede had gone 0-6 with a 7.05 ERA over his previous eight outings.

“A lot of confidence translated from that Dodgers outing,” Beede said. “But really it’s just a byproduct of work from weeks before that and just piecing it together.”

Showcasing his sharp command, Beede allowed only two Marlins to reach base over the first six innings Friday, yielding a leadoff single to Starlin Castro in the second and a two-out single to Harold Ramirez in the fourth. He was removed from the game after issuing a one-out walk to Ramirez in the seventh and departed after throwing 87 pitches.

“He went out there and did it again tonight,” Bochy said. “Good stuff. Good fastball, it had good life to it. He had a good breaking ball going, changeup. Really nice job carrying that game in L.A. into this one. He got us deep in the game and could have stayed out there a little longer. I just had Rogers ready. It couldn’t have really worked out better.”

Rogers relieved Beede and recorded the final two outs of the seventh before coming back to strike out two in a clean eighth. After spending seven seasons in the Minors, the 28-year-old Rogers has made the most of his long-awaited opportunity with the Giants, posting a 1.74 ERA over 10 1/3 innings over his first 10 big league appearances.

“Those guys have been super impressive all year,” Beede said of Rogers and Anderson, who converted his second save in place of injured closer Will Smith. “Rog, what you see from him now is what he’s done his whole career in the Minor Leagues. I’m super happy for him to be able to come up here and continue to be Tyler Rogers. The Giants are lucky to have a guy like that who they can throw out there in big-time situations.”
