"There's no getting around it, we're having a tough time getting runs on the board," Bochy said before Saturday's game.
Posey suffered his injury Wednesday night and the Marlins shut out the Giants, 1-0, on Thursday night. Shaun Marcum held the Giants scoreless for the first five innings before they got to the Brewers right-hander, capped by Crawford's slam in the seventh.
"That's a big hit," Bochy said. "Especially since we were down and had just been shut out the day before. We're all still thinking about Buster. He's in our thoughts and we're going to miss him."
