DENVER — Madison Bumgarner scattered four hits over seven innings, Hunter Pence hit a two-run homer and the San Francisco Giants ended their longest losing streak in three years with a 5-2 victory over the Colorado Rockies on Sunday.
San Francisco had lost six straight, its longest skid since dropping seven in a row from June 26-July 1, 2010. The World Series champions had dropped seven straight road games.
Bumgarner (8-5) struck out five and walked three, improving to 4-1 with a 2.18 ERA in his last five starts. Sergio Romo pitched a one-hit ninth for his 19th save in 21 chances.
Buster Posey put the Giants ahead with a solo homer in the third.
Colorado's Michael Cuddyer singled in the eighth off Sandy Rosario, extending his hitting streak to 27 games. The streak is the longest in Rockies history and in the majors this season. He has reached base safely in a franchise-record 45 straight games.
Drew Pomeranz (0-1), making his 2013 big league debut after being recalled from Triple A Colorado Springs, allowed four runs, seven hits and four walks in 4 1-3 innings.
San Francisco extended its lead to 4-0 in the fifth on a run-scoring throwing error by first baseman Jordan Pacheco on Posey's grounder and Pence's 13th homer.
Carlos Gonzalez hit his 22nd homer of the season in the sixth.
