Brandon Crawford led off the 10th inning with a splash homer to give the San Francisco Giants a 5-4 victory over the Colorado Rockies on Sunday.
Pablo Sandoval homered and Angel Pagan drove in two runs for the Giants, who bounced back from a 1-0 loss on Saturday to take two of three in the series.
Wilin Rosario and Justin Morneau homered for the Rockies, who have lost 15 of their last 18 games in San Francisco and have not won a series here since 2010.
Crawford turned on the second pitch thrown by Rex Brothers (1-1) and drove it into McCovey Cove for his first career walkoff homer and first splash homer.
Sergio Romo (1-0) pitched a scoreless 10th for the win.
