DENVER - Nolan Arenado hit a game-ending single with two outs in the ninth inning Saturday to lift the Colorado Rockies to a 2-1 victory over the San Francisco Giants - losers of six straight for the first time in three years.
Colorado's Michael Cuddyer singled in the first inning to extend his hitting streak to 26 straight games.
Todd Helton was walked by reliever Jeremy Affeldt (1-4) with two outs in the ninth for Colorado's first baserunner since the second inning.
Josh Rutledge, pinch running for Helton, stole second and scored when Arenado singled up the middle on a 2-2 pitch to help the Rockies return to .500 at 41-41.
Rafael Betancourt (2-3) got the win in his first appearance since May 31. Betancourt missed the past month with a groin injury.
The Rockies got another strong start from pitcher Jorge De La Rosa. De La Rosa allowed one run on six hits over six innings. He stood to pick up the victory until giving up an RBI double in the sixth to San Francisco catcher Buster Posey.
