SAN FRANCISCO (AP) -- Hunter Pence hit a three-run homer in the first inning that held up, Buster Posey added a late RBI single and the San Francisco Giants snapped the Colorado Rockies' five-game winning streak with a 4-2 victory Monday night.
Madison Bumgarner (2-0) won his sixth in a row against the Rockies and owns a seven-start unbeaten run in the rivalry. The left-hander began his career 0-3 against Colorado in five starts.
He struck out five and walked five in 5 2-3 innings Monday, allowing two runs and five hits.
One of those was Carlos Gonzalez's long homer to right in the third. The ball bounced off the pathway and splashed into McCovey Cove.
