Gonzalez isn't starting Wednesday against Atlanta due to a stiff back, Susan Slusser of the San Francisco Chronicle reports.

EDGE Analysis

Gonzalez started the last four games, and manager Gabe Kapler said that the 27-year-old would have been in Wednesday's lineup if he was healthy. It's not yet clear whether Gonzalez will be available off the bench Wednesday, but he'll be able to rest Thursday since the Giants have a scheduled day off.
