The San Francisco offense has gone nuts in the last three games despite plenty of injuries, and it shouldn't have a tough time keeping it going in a series against three Cincinnati pitchers that have been incapable of limiting much of anyone. The Reds' Keyvius Sampson will take the first shot at changing that Monday night at AT&T Park, where the Giants have started a nine-game homestand with three straight wins. San Francisco (75-68) won 10-3 Sunday to complete a sweep of San Diego with 27 runs scored and a .340 average.
