The team has just one home run in its last 22 games at home, with the last Giants batter to hit a home run being Gregor Blanco on May 14 against the Rockies.
"That's a tough one," manager Bruce Bochy said. "You don't want guys trying to get home runs. We have more power, I think, than we've shown. I think Pablo [Sandoval's return] will help."
In 32 games at AT&T Park as of Tuesday, the Giants have a Major League-low six home runs at home this season, eight fewer than the next lowest club, and 46 fewer than the Major League-leading New York Yankees.
"If you start looking at that number and then all of a sudden we want guys getting home runs, that will just compound the problem," Bochy said.
Even with their power outage at home, the Giants are still 10-6 during the homer drought.
"Through all that, we've played really well, I thought," Bochy said. "We've found ways to score runs, that's the important thing. The home runs are nice, but when they're not coming, hopefully you're getting key hits."
