Matt Chapman contributed a two-RBI single to a game-breaking, three-run eighth inning as the San Francisco Giants made it two in a row over the visiting Chicago Cubs with a 5-1 victory on Tuesday.

Six San Francisco pitchers combined on a four-hitter.

In a bullpen game with five starters on the injured list, the Giants got shutout relief from Sean Hjelle, Taylor Rogers, Ryan Walker, Tyler Rogers (1-2) and Camilo Doval after opener Randy Rodriguez allowed Chicago's only run in the third inning.

By then, the Giants had taken a 2-0 lead.

Jorge Soler led off the second against Cubs starter Kyle Hendricks (1-5) with a single. After Chapman walked, Michael Conforto opened the scoring with a single to right, which also sent Chapman to third. One out later, David Villar's sacrifice fly made it 2-0.

The Cubs responded with their only scoring in the third when Nico Hoerner drew a two-out walk, stole second and scampered home on a single by Michael Busch.

Rodriguez was pulled at that point, charged with one run on one hit in 2 2/3 innings. He walked two and struck out five.

Hjelle served up a single to the first batter he faced, Cody Bellinger, but then stranded the potential tying run at third by striking out Seiya Suzuki.

The Cubs got only one other baserunner into scoring position the rest of the way, that coming after Hoerner singled with two outs in the fifth. Taylor Rogers came on and walked Busch but then struck out Bellinger to end the threat.

Seeking a second win over the Giants in a week, Hendricks was pulled after seven innings, having allowed two runs and five hits. He walked one and struck out four.

The Giants then jumped on Cubs reliever Colten Brewer for their three-run eighth. Soler made it 3-1 with a sacrifice fly before Chapman came through with the biggest hit of the night.

Brett Wisely and Luis Matos had two hits each for the Giants, who have opened a homestand with two straight wins after dropping five in a row to complete a road trip last week.

All four Cubs hits in the game were singles.
