The San Francisco Giants provided a glimpse of the opportunistic offense they thought they had coming into this lost season. Buster Posey hit three RBI doubles, Brandon Crawford drove in three runs and had three hits, and the Giants beat the San Diego Padres 8-0 on Friday night to ensure they won't finish with a 100-loss season. Joe Panik added a run-scoring double among his four hits to back Chris Stratton (4-4).
