Sandoval played seven innings at third base on Saturday, but for the second game in a row did not get any ground balls.
"That's two games in a row," Bochy said. "It's hard to believe that in two games he didn't get any ground balls."
Bochy said he anticipates the makeup of the infield changing by a game-to-game basis, with Sandoval getting playing time at both third base and first, and Marco Scutaro playing at different infield spots.
"It's nice to have the versatility where you can move guys around," Bochy said. "I think that'll play a major role down the stretch here. If somebody gets a little nicked up or is not seeing the ball well, it's nice to have this depth."
While Scutaro has played shortstop in the past, Bochy said that Brandon Crawford's hold on the position is still safe and that the second-year shortstop will continue to get "the lion's share" of the playing time at the position.
"You have to like the way he's playing defensively and swinging the bat," Bochy said.
