Gonzalez (back) reported to Triple-A Sacramento on Wednesday to begin a rehab assignment, Susan Slusser of the San Francisco Chronicle reports.
EDGE Analysis
Gonzalez is expected to play about five innings during his first rehab appearance and should continue building up to full games over the next few days. The 26-year-old has been on the shelf with a low-back strain since June 23, so he shouldn't require significant time in the minors to get back up to speed.
