Trevor Story had no idea he was sparking a record-setting effort when he led off the fifth inning with a home run. Story and Nolan Arenado each homered and drove in three runs, and the Colorado Rockies set a franchise record with their 13-run inning in a 17-7 victory over the San Francisco Giants on Thursday night. Gerardo Parra had two hits and three RBIs in the fifth, when Colorado sent 17 batters to the plate.
