While the Giants have won 19 of their last 25 games on the road, they have lost 15 of their last 24 games at home.
"It's got to pick up; we know it," Giants manager Bruce Bochy said. "There's no reason why we haven't played quite as well here."
The Giants are 3-4-1 in their last eight series at home, but are still 40-31 (.563) on the season at AT&T Park.
"Early in the season we were very good here," Bochy said. "It's going to be important that we put that behind us and play well here."
