SAN FRANCISCO — Matt Chapman's two-run single highlighted a three-run eighth inning and six San Francisco pitchers combined for a four-hitter as the Giants beat the Chicago Cubs 5-1 on Tuesday night.
Michael Conforto added an RBI single, and David Villar and Jorge Soler had sacrifice flies to help the Giants win their second straight following a five-game skid.
''It's huge,'' San Francisco catcher Patrick Bailey said. ''I mean we obviously didn't like how the road trip went but just kind of got to show up the next day and try to win a ballgame, and hopefully we can keep things going.''
Conforto's run-scoring single gave San Francisco a lead in the second inning. Villar's sacrifice fly made it 2-0.
Michael Busch had an RBI single in the third for the Cubs, who lost for the fourth time in five games.
''It was a quiet night," Cubs manager Craig Counsell said. ''I think we had three at-bats with runners in scoring position. We didn't have an extra-base hit. You're not going to have a big night offensively with numbers like that.''
San Francisco rookie reliever Randy Rodríguez made his first career start, allowing one run and one hit with five strikeouts and two walks in 2 2/3 innings.
''He was electric,'' Bailey said. ''Lights out. His stuff's been like that all year. I think he really executed well today.''
