Rockies win, 2-1.
Colorado continued to lean on the efforts of Michael Cuddyer, who extended his hitting streak to 26 games with a single off of Giants pitcher Matt Cain in the bottom of the first.
Posey evened things up by driving in Marco Scutaro with a double. Otherwise it was a pitcher's ball game heading into the ninth.
Arenado hit a walk-off single to give Colorado the win. San Francisco's hitting continues to disappoint as they failed to even create opportunities to score. They've now lost six straight games, seven straight on the road.
The Rockies improve to .500 while the Giants have a losing streak they haven't had since 2010.
