Brandon Crawford played the role of the hero in the sequel on Saturday afternoon, belting a three-run home run that rallied the San Francisco Giants to a second straight low-scoring win over the visiting Colorado Rockies, 4-3 in a battle of National League West clubs.

Right-hander Logan Webb combined with four relievers on a nine-hitter as the Giants won their third straight overall and second in a row over the Rockies.

Ryan McMahon smacked his fifth home run of the season for the Rockies, who lost for the sixth time in their last eight games after an Opening Day win over the Los Angeles Dodgers.

After McMahon's homer, a two-run shot, had given Colorado a 3-1 lead in the fifth, Alex Dickerson and pinch-hitter Wilmer Flores led off the last of the sixth with consecutive walks off Rockies reliever Ben Bowden (0-2).

One out later, Crawford scaled the brick wall in right field for his second homer of the season, a three-run blast that produced the final scoring in the contest.

Crawford had been the offensive star of Friday's 3-1 win as well, ending a scoreless tie in the seventh inning with a two-run double.

Giants relievers Caleb Baragar (2-0), Reyes Moronta, Tyler Rogers and Jake McGee combined to shut out Colorado on one hit and one walk over the final four innings, with McGee earning his second straight save and fourth of the season.

Webb worked the first five innings, allowing eight hits and three runs. He walked two and struck out six.

Neither he nor Colorado starter Chi Chi Gonzalez got a decision. Gonzalez also was pulled after five innings, charged with one run on four hits. He walked three and struck out one.

The Giants' Dickerson and Rockies' Raimel Tapia exchanged early RBI singles to account for the 1-1 tie that was broken by McMahon's homer in the fifth.

Tommy La Stella had a double and a single for the Giants, who have allowed three or fewer runs in five straight games.

McMahon, Tapia and Trevor Story collected two hits apiece for the Rockies, who out-hit the Giants 9-5.

The Rockies had scored five or more runs in six of their first seven games before totaling just four in their first two games in San Francisco.
