Pinch-hitter Rafael Ynoa snapped a sixth-inning tie with an RBI double, Eddie Butler was backed by stellar defense over six shaky innings and the Colorado Rockies beat the San Francisco Giants 6-4 on Friday night. Charlie Blackmon added a solo homer and DJ LeMahieu drove in two runs as Colorado beat the defending World Series champions for a fourth straight time this season. The Rockies swept a three-game series last week in which they limited the Giants to three runs. San Francisco matched that total by the third inning.
